[Mobile] Staying connected in Korea – Prepaid SIM card

Staying connected to the internet world is important for us even when we are on vacation.
So today i’m going to introduce a few methods where you can get a prepaid sim card for calling/internet surfing.
It may not be a full list of what are available in Korea but as of my best knowledge. :)


How to get a prepaid SIM CARD?

Method 1 - EG SIM CARD Event with KTO

1) Download ‘Visit Korea 2.0″ Smart Phone App.
2) Visit URL: http://air.koreaphone.net/join/join.asp
3) You will be brought over to this page to order your SIM CARD.
Before you start to fill up the form, you may wish to check the opening hours of the collection point.


4) A 2,000 won fee for calling is included in the SIM CARD for free. ( till Jun 2013 )
Voice rate: http://air.koreaphone.net/chargeRate.asp
If you need to top up the voice fees, you can login to http://www.egsimcard.co.kr or download EG app to buy credits.
(This to be done when you are in Korea when you got the phone number.)

5) With the SIM CARD, you can now start to ‘BUY’ a data plan to surf net!
There are 3 data plans for you to choose : 100 MB (5,500 won) , 500MB (11,000won), 1G (16,000won)
For my 26 days in Korea, I paid 1GB plan to tweet, Facebook, Instagram, check emails on iphone :)
With every top up, your Data plan would automatically be extended for another 30 days.
(This to be done when you are in Korea when you got the phone number.)

Method 2 – EG SIM CARD official website.

1) Visit http://www.egsimcard.co.kr
2) You can purchase the sim card with voice plan at the same time when you yet to arrived in Korea.
3) I was reading from EG official Facebook page: IF you buy their SIM CARD at www.egsimcard.co.kr , they can deliver it to your hotel for free! ( 1-2 biz days)

I would highly recommend to contact them via Facebook if you have any doubt in their services.
Their responses are fast and always eager to help you with any issues.
Have tried sending my request to them at 11:30PM SGT and they reply in the middle of the night! :)
Well having said so much about the EG SIM CARD. Let me share my experience with you …

Depends where is your desired pick up location, mine is at Incheon Airport.
Upon arriving, heading towards EXIT 7 and look out for K BOOKs shop.

Yeah! Found the collection counter!

Showed him my confirmation number and passport :)

My very own EG Prepaid card… Currently only available in Micro and General SIM CARD size.
Nano SIM card (iphone 5 ) users, you need to cut the SIM card into Nano size yourself. :/
This is what I read from the EG Facebook page. Hopefully nano sim card will be  available soon. :)

Besides the Mirco SIM CARD, there is a A4 instruction paper telling you how to insert SIM CARD, How to Call overseas, How to TOP-up and calling rates.
Click here to take a look …

littlemisshoo’s tips:
You can request the staff to insert  and test the SIM CARD for you. Just to ensure everything works fine.
If your phone doesn’t detect the network on your 1st try, please turn off and switch back to try detect again.
It uses  OLLEH network .

Now it’s time to buy some credits to connect back to the internet world!!

There are 2 ways for us to top. i.e: Website or Smart phone app.


Since I will be in Korea for 26 days, so I thought of topping up $50,000 won to Voice and 1G Data.
Let’s top up the Voice first.

Yup successfully completed :) With the initial free 2,000 won, I have a total of 52,000 won :)

TOP up Data plan – Transfer $$ from Voice to Data. Select the desire plan.

After transferring 16,500 won to Data plan. i’m now left with 35,500 won for my voice + free incoming calls haha.

If you are worried you might over spent and not sure when to top up. Fear not!
EG Mobile have these 2 services to keep you aware.

Check Balance, Check Usage History

There will also be SMS send to you when your Data usage are getting low. Here’s what I’ve received.


In case you would like to top up via website here’s the url:  www.egsimcard.co.kr.
Sign up as member and enter your phone number.
Not only you can top up, you will gets to see the SIM card expiry date too :)

This is a total money saver for me as it’s my 1st time spending less then $50,000 won with balance of 10,500won voice!!
1GB of data was completely used up on my last day and I top up another 1 GB for my sis to use for another week! Yup all within 40,000!
Highly recommend for tourist in Korea.


Another Telco company S Roaming recently joins the prepaid sim card market.
There are 2 prepaid SIM card ( Voice ) and (Voice + Data Plan).
You may click here to read more. ^^

I’m more interested in their voice + data plan so let’s do a comparison between EG Mobile and S Roaming..

S Roaming Voice Rate for prepaid

EG Mobile Voice Rate for prepaid

Not so much different… NOW let’s look at the data plans..

S Roaming Data Rate for prepaid

EG Mobile Data Rate for prepaid

WOW.. that a huge different…With EG Mobile plan, I can have 2GB of data to use where S Roaming only offer 1 GB with almost same amount of money.


EG Mobile – It’s easily done via smart phone apps, website and other services counters.
S Roaming – To call S Roaming call center for top up. Yyann another Korea Travel Blogger has mention it on her post here :)


History Checking

EG Mobile – It’s available on apps.

S Roaming – To call S Roaming Call center for latest usage.

You may wish to use S Roaming if your SIM CARD (iphone 5 – Nano ) type is not available in EG Mobile :)



Olleh KT has also quietly launch it’s  prepaid SIM card that not long ago. Check out on their new English website :)

How does it works? Click here to read on the rental process.


It seems that KT Olleh don’t have a data plan like S Roaming and EG and you will need to pay as your surf.
So this is a very expensive option for people who likes to tweet/facebook/check emails.. :/
If you have any questions: https://twitter.com/olleh_expats
The staff would takes about 1-2 days to reply.

Another  prepaid sim card by KT Olleh where it is design for students or workers who will be in Korea for a longer period of time.

Top up: Available at KT Global Center. For list of location click here.

**Personal experience: I’ve tried to top up at several GS25 stores, the staff told me they don’t have this service.

To check you balance: Call 1500 or by dialing #0

Here are some of the hidden rules:

1) You have to wait for 3 days after reaching Korea to apply the prepaid SIM card.
2) You can only activate your SIM CARD on weekdays.
3) Activate them at only  KT Global Center not available at those retail shop.
4) A deposit ( cash/credit card) has to be made before you can ‘rent’ their SIM CARD.
5) At the end of your trip, you will need to return your SIM card to get back your cash. Some paper work needs to be sign.

Alright …let the photos do the talking..

Oh yes errr…these photos are taken back in Sept/Oct 2012. ^^
KT Global Center @ Gangnam

After arriving in Korea for 3 days, it’s time for me to apply for prepaid SIM card.
Really, reali, ‘jin jia’ need to get one so that I can tweet, FB and Instagram.
But I was being told to come on weekdays as the system is not available on weekends.
Seriously!! In this century i’m not sure why KT is not ready to take in walk in customer for a prepaid SIM card registration. T_T
Nevertheless, I shall come back again on a weekday.

This time I visited the Global Center at Hongik University Exit 9. ( 10 days later )

English Speaking Staff :)

Just as I thought I would be able to get the SIM card, the KT system is throwing me an error.

And now I wasn’t able to get the SIM for the 2nd time.. Grrrrr KT staff ask me to come back some other days and try again.

Yes i’m fuming mad deep inside but to walk away and come back another day. A big boohoo!

Upon my 3rd attempt ( 2 weeks later), somehow the staff managed to find my records in the system and issue me a SIM card.
Too bad no photos to show as the staff put in the card and activate for me.
At the same time, I was planning to top up some money into the card.

Knowing I wont make many calls, so I opt for 20,000 won top up.

Surfing the net would cost me a lot by using this pre-paid card, the counter staff suggest i sign up for a monthly plan 8,800 won to enjoy 300 MB data usage.

I actually assume i would need to pay in advance for the data plan 8,800 won but no i don’t need to.
They will send me a bill to my guest house asking me to pay or settle the outstanding amount when i return the SIM card.
With the data plan i can tap on Olleh network to surf internet, but later to realize the network are strongest  when i’m near subway station or buildings where they have strong Olleh signals.

So from time to time i will have to turn on my 3G data and top up SIM card a few times.
The top up options at convenience shop like GS25, CU is not available. Either the staff are not well trained to do that or the service is only available at certain stores. Hence, i ended up returning back to Global Center a few times.

Oh yes they do SMS me when my credits are running low so i know when to top up.

At the end of my trip, i went back to Hongik Univ Global Center to settle some paper work and paying outstanding bills.
The process is fast but only to learn i have to go to another KT billing centre to pay for my monthly 8,800won bils.
I really don’t know how KT billing section works, making me fed up in getting bills done.
The good thing is i still have some time before catching the air port bus and the billing centre 2 street away.

Lucky i was there early and I was quickly served by the KT customer service staff.
The service staff here don’t have an English speaker like the ones in Global Center but lucky she understand my ‘broken’ Korean :)
Payment was done pretty fast, sign papers , gave my credit card to settle the bills and I’m out of there in 10mins.

Hope this is useful for you when you are deciding which type of prepaid card to use. ^_^


Wifi on Demand

I knew about this when i was traveling in Korea Aug 2012.
KT Olleh offer 2 types of demand wifi services (1 hr @1,100 won or 1 day @3,300 won)
Click here to read more.
So here i am decide to give it a try because there’s no prepaid SIM CARD.
To have wifi on demand is amazing cool!

So from the information that i’ve gathered, i could buy the wifi pin from any of the convenience stores GS25/7 Eleven/ CU.
But i was wrong, only GS25 are selling the pin after checking with a few brands at different stores.

Bought a day of wifi credit @3,300 won.

With the pin number, i quickly launch my wifi English page and getting ready to registered.
Select “Register Prepaid Card”

Enter your particular

You maybe unsuccessful on your 1st try and keep getting error like the one below.
Just keep trying and you will get it connected eventually.
On my 1st attempt to connect, it took me 2 days. But again I didn’t try it again and again just try it at different time of the day. ;p

Once you are connected to the wifi, you will see your network has successfully conntect to Olleh Wifi


That’s all for now everyone… Hope you will find this useful when planning your trip to Korea!
This is base on my experience with the service providers and hopefully you have a pleasant one.

    Ros, actually you can just buy the data plan will do no need the calling plan.
    Just buy Skype credit and with wifi/data plan you can make overseas to any mobile phone user.

    You can also rent Sroam egg…portable 3G router. Then 3-5 user can connect to it wirelessly to the internet, no need to change SIM card on existing phone, it about $7000 Won per day.

      Hey Patrick

      Thanks for sharing with us ^^.
      Yup if you don’t need any local number, you can rent the ‘EGG’ from Telco provider.
      I have not tried on this before not sure how good are the signal.

      Anyone wanna share your experience on ‘EGG’ here? :)

        I’ve rented the Wi-Fi egg for 2wks n it’s fabulous! From Jeju to Seoul, signals forever strong even in outskirts area! Only disadvantage u need to charge wz powerbank when out as it depletes very quickly. Can b shared up to 5 mobiles. Reservations is a must online,pickup at arrival hall.

    Hello! Thanks for the information!

    So from all the choices, EG sounds quite convenient. Which will you recommend? Cause for me, I will be in Korea for around 43 days.


    • May 29, 2013 at 10:32 pm

      Dear Serene

      I would recommend EG SIM Card :)
      As it is easy for you to top up/check balance/affordable data plan :)

    I went in April 2013 with my friend. We decided to rent an iphone5 from olleh with a local number, unlimited data plan for 8000KRW a day. It was done in Incheon airport. My friend then turned on the personal hotspot on the iphone5 and both of us were able to online the whole time on our own smartphones which we were more used to than the iphone5.

    We used the local number on the phone to participate in Music Bank pre recording as well as 4 Minute’s fan sign. Thanks to the advantage of having a local number, we were lucky to be selected to participate in both events!

    At the end of our 9-day trip, the bill was 72,000KRW and we splited into two. Well worth it!

    • June 3, 2013 at 10:44 pm

      Dear Debbie

      Thank you for sharing with us ^_^
      For those who travel with friends, this is an another great way to save $$$$ woohoo

      July 29, 2013 at 11:25 pm

      I hope to be able to follow what Debbie did, except I don’t think I will need unlimited data. I’m only there for 10 days. Hopefully they have a cheaper option. Does anybody know where in Incheon airport they found this service?


      • July 29, 2013 at 11:38 pm

        Hi Andrew,

        You can find phone rental booth after you come out from custom :) It’s easy to spot it.
        There are a few companies offering them so do compare the prices before settle down for one.
        Good luck!

    Hello littlemisshoo,

    the phone has to be unlocked before it can use the EG SIM card am I right?
    How do we know if our phone is unlocked?

    • June 8, 2013 at 10:01 pm

      Hi Huanny,

      If you are not sure if the phone is unlocked or a not, you can bring your phone down to your local provider to help you check.
      A unlocked phone means when you replace it with another Telco provider (A) SIM card, your phone will pick up (A) network.

      In some countries, some of their Telco provider ‘lock’ the phone when consumer buy it from them (cheap).

      Hope this helps!^^

    Hi! Just want to ask what do you mean by ‘ With every top up, your Data plan would automatically be extended for another 30 days.’ for EG simcard? Is it a top up to the simcard or just topping up my data by deducting for the amt I have in my prepaid? Does this simcard have access to olleh wifi hotspots too?

    • June 14, 2013 at 11:31 pm

      Hi Miju ^^

      Top up means by adding money to the voice account.
      The only to add money to data account is by transferring money from voice account.
      You can activate the hotspot too :) You can visit their facebook page for double verification.

      Hope this helps!

    Hello! Do you know if the 2nd option (S Roaming) offers nano sims for iPhone 5?i checked their website and can’t find where they’ve stated it… Very desperate to find a nano sim as I will be staying therefor the whole summer!

    • June 14, 2013 at 11:37 pm

      Dear Karen,

      I’m not 100% sure but I would suggest you to call the S Roaming booth in Incheon to check.

      Have a good summer in Korea!^^

    Hi! This is by far the best, most detailed information regarding phone/SIM card rental I’ve found online – THANK YOU! Do you know if there is a minimum amount you have to put on the EG SIM card to start with? We are thinking of renting an egg but also getting the EG SIM so that we have a phone number and coverage outside of wi-fi (we will be in some rural spots). Thanks!

    • June 17, 2013 at 2:13 pm

      Thank you Amy!
      When i got my EG card, there is a free 2000won amt in it.
      I think min is 10,000won. frm the app, there is a list of amt for you to choose

    Thanks for the information!! I’m about to start semester in South Korea, actually it would be 4 months. I can use EG sim card right? there is not limit on time to use it, isn’t it?

    About your book! I really want it, will I find it in Korea?

    Thanks thanks thanks, really love your blog :)

    • July 23, 2013 at 2:33 pm

      Dear Kathey,

      As long as you keep top up cash before the expired date you can continue to use them. Each time you top up the expiry date will be extended. You can also login to the EGG website to check your SIM CARD expiry date :)

      My book has sold out in Kyobo Seoul. Would you want to order directly from me? ^^

      Hope the information helps!

    Thanks much for the comprehensive sharing.

    I would just like to find out on two other details.

    1) Are iphones bought in Singapore compatible with their SIM?
    2) Are network coverage similar over the entire country?


    • August 10, 2013 at 12:25 am

      Dear CS

      Sorry for the late reply.

      1) Are iphones bought in Singapore compatible with their SIM?
      Yes it is compatible. I am using iphone 4s.

      2) Are network coverage similar over the entire country?
      Olleh network covers the whole country.

      Hope this helps! ^^

    I’ve got a question to ask, about the KT olleh wifi (this is probably a stupid question, but I really am not sure how this works), the services they offer, 1 hour, does it expires one hour AFTER you activated it or counts the minutes that was used? Say, if I activated it at 9am, but only used it for 10 mins, Will it still expires at 10am? Or I have 50 mins more to use? As, I don’t plan to use it much, only to access google maps when I’m lost or looking for a place, so will probably just used a couple of minutes here and there.

    Thanks and this really is very informative, especially for people like me! :)

    • August 10, 2013 at 12:21 am

      Hi Kat ^^

      It expires after 1 hour you activate it. and Yes it is base on time and not on bytes.
      Hope this helps!

    I read almost all of your review and it is by far the best comparison of Korean cell plans for foreign people…that’s a misfortune that I didn’t read it before comin’ here :(
    Actually I’m stayin’ the whole next week in Seoul. What’s in your opinion the best solution? I own an unlocked phone by the way…

    Thx in advance ^^,


    P.s. Did u write a book bout Korea?

    • August 13, 2013 at 7:28 am

      Dear Jacopo

      Since you will be there for 1 week and if you would like to be internet connected. i would suggest you getting EG SIMG CARD. :)

      ANd… yes i wrote a Korea Travel Book :)

      Enjoy your holiday!!

    Thank you for your great review. I have a plan to stay in Korea for a month in this October. I just wonder about their coverage area and speed of data usage.

    Thank you

    • August 18, 2013 at 12:28 am

      Dear Khanin

      From my humble experience, i’m using KT Olleh network and the coverage works well. Not sure how to measure the speed of data usage. But I have no issue watching youtube, checking emails, FB updates etc.
      The internet connection works best around subway station :)

      Hope this helps!

  17. Min
    August 17, 2013 at 10:03 pm

    Can you apply for an Olleh KT pre-paid SIM card as a tourist? As in not the rental type? So that we can keep the SIM card as a souvenir?

    • August 18, 2013 at 12:22 am

      Hi Min

      Yes you can apply Olleh KT-prepaid card as a tourist :)

  18. Vinh Ly
    August 21, 2013 at 7:44 pm

    Do you recommend the EG Mobile or the KT option?

    • August 21, 2013 at 9:13 pm

      Dear Vinh

      I would recommend EG because it is also on the Olleh KT network and has a user friendly top up function ( Mobile app).

      Hope this helps!

    Is it a must to pre-order the SIM Card? or it will be ready available to be purchased at Incheon Airport?

    Thanks for your review!
    I will be staying in korea for 3 months, and I mainly just want to be able to whatsapp and surf the net on the go. don’t really need to make phone calls.
    Do you think it would be better for me to go for the EG mobile data plan or the Olleh data or to just get the wifi egg instead?? ><
    Also, you've mentioned that you used the 1GB data for approx one month, how often do you use the data on a daily basis?
    Thank you so much!

    • August 26, 2013 at 10:29 pm

      Hi Tiffany

      I used 1GB for 1 month mainly on update photos to FB, instagram, twitter , what’s app and checking emails.


  21. Ashaf
    August 28, 2013 at 12:16 am

    Thank you for such a brilliant information!
    I was wondering about how to buy a credit for top up on EG? I can only buy it with using credit card or is there any places who sells EG pin or something so I can pay them with cash? Sorry if it’s already mentioned before, but can I use the data directly on EG right after I receive and install the simcard into my phone after my arrival at Incheon? Or will I have to wait for 3 days? thank you in advance

    • October 3, 2013 at 3:55 pm

      HI Ashaf,

      You can download the app EG SIM CARd to your smart phone and top up.
      After buying the SIM CARD from internet, you can request EG SIM CARD team to send the card to your hotel/guesthouse.

      For any questions, you can direct to them at


      Hopes this helps!

    Hi, this is best review of mobile voice/data access with mobile phone/pad in Korea. I have though a couple of questions (hopefully the answer are not already in your review):
    1. I plan 4 weeks leisure trip and plan to preorder EGSimCard in advance with local delivery – is it possible to ask delivery to K-Books (need probably to order at least 3 days inadvance of arrival date) or other places at Incheon?
    2. The stated price says KWN 20000 (30000 depends on selection) – does that include any data/voice service, or is it then necessary to top-up with whatever data plan one wants (500MB or 1 GB)?
    3. If one does not top-up before the credit is expired does one have to “buy” a new Sim Card? or is it possible to top-up even after credit is gone to zero?

    Thanks in advance
    Claude Thomassin

    • October 3, 2013 at 3:52 pm

      Dear Claude

      Sorry for the late reply. But this is to my best knowledge …

      1) EG SIM card can be delivered to your guesthouse or hotel.

      2) The amount is for the voice. You have to transfer some $$ ( from the 20,000 KW) into data plan

      3) When your SIM card fall below zero or expired, you can top up to active it again.

      For any questions, you can visit EG facebook for any questions :)


      Thank you!

    Thanks for sharing on your detail pre-paid sim card options in Korea! I got a Verizon iPhone 4S (uses CDMA) which I’m hoping to unlock before I travel to Korea next week for 2-3 months and this is definitely a win-win help for me!

    I’ll definitely need call/voice + data so I’m looking at the different options you laid out and debating which one has the best deal of them all that I can squeeze my minutes out of.

    You recommended EG the most with the app and etc, but do you think it also have the best rate among the competition?

    Lastly, I also need another pre-paid option for my parents who’s traveling but they don’t have a phone to carry like I do. Do you know any place where you can buy a temporary phone? I heard Incheon’s services are a complete rip-off and want to avoid that option for me or my parents.


    • October 3, 2013 at 3:00 pm

      Dear Scott

      Currently EG offer the best rate and data plan for traveler like us.
      For rental a phone, the best place would be in Airport because in town they are limited places (like KT Global Store).
      To get cheap rental fee for phone (Not Smart phone) , you can search for discount coupon or online registration offer these offer are usually pre-book before you enter Korea.

    Was just wondering if I would be able to purchase the EG sim cards when I reach Incheon airport directly, or do I absolutely have to pre-order it..

    Just to check whether this EG SIM CARD can be used for Samsung note?
    thanks. :)

      Hi Stellina

      Yes EG can be used on Samsung Note.
      ( My sister uses on her Note 2 )

      Hope this helps.

    Thanks a lot for the info!

    Just wondering, did you have to give them an ”ARC” (alien registration code?) or a citizen ID number? Because according to other websites, it seems they are asking for it and the delay for getting an ARC would be like 2 weeks..!

    • October 21, 2013 at 3:34 pm

      Dear LorieQ

      You don’t have to give them ARC or Citizen ID. Passport number is the one they are looking for :) – That is for EG SIM standard.

    May I ask what is data limit when I first purchase the EG SIM Card.

    Is it necessary to topup the SIM Card after activating it? I will be in Korea only for 9 days.

    Thank You!

    Hi^^ thank you for you detailed explination! I would like to ask,is it nessesary to rent/apply/buy these or would it be just fine without? (I know the question sounds quite weird:P) im using a iPhone 5,never been to Korea before(although im very excited to!),and am heading there in nov for a week:)

    • October 21, 2013 at 3:11 pm

      Dear Joy

      I’m happy you are going to Korea soon!
      If you are there for a week, I think should be ok not to rent.
      Again it will boils down to your usage : like checking emails,facebook, instagram etc
      There are a lot of free wifi places in Korea too
      If you need wifi, you can walk into any café in Korea which thy provide free for their customer :)

      Enjoy your holidays in Korea!

    The shop changed location. The current shop to get the simcard is located at the airport train terminal. Kbooks doesn’t sell EGsim anymore.

    • October 26, 2013 at 6:18 pm

      Hi Samuel,

      Yes you are right :)
      And i just read from ther facebook annoucement: starting from 28 Oct 2013, EG Sim Card is available to pick up from K Books store again.

      Thank you for sharing your experience with us ^^

    Just to add more details on your blog post, Korea telcos actually register the phone that you use with the SIM card you purchase from them. In a sense, your phone will be SIM-locked. If you travel to Korea often, I would suggest you stick to one telco company and keep the SIM card for your next visit. Attempting to put in new SIM card on the same phone without verbally asking the telco, where your original SIM card come from, to stop the service is just a pointless thing to do. And if you request to stop the service, all remaining value in the prepaid card is rendered non-redeemable.

    The KT Olleh Global Shop (or whatever is called) in Hongdae actually have an excellent costumer service (2 counters dedicated for English-speaking costumers). You can pay the prepaid data plus package up front together with your SIM card purchase. To be able to use this data plus package, you have to have a minimum value of 5000won. AFAIK, you can only ‘top up’ this prepaid data plus package by going to the KT Olleh Global Shop personally and show them your passport.

    And lastly, it is illegal to transfer your SIM card to someone else.

    PS: This is based on my experience travelling to Korea in April & July 2013.

    This is very detailed thank you so much!

    But to confirm,

    I want to /buy/ a local korean number (to get in kpop events etc) and also data usage. (I have an iPhone 5C.)

    When I say I want to buy, I mean I won’t want to return the simcard at all!

    I am staying for 21 nights.

    Which do you recommmend? :)

    And what steps do I have to take to get the sim by the time I arrive at Korea?

    • November 11, 2013 at 3:59 am

      Hi Esther

      You can get EG SIM card. You don’t have to return the SIM card. :)

    When i visit “http://air.koreaphone.net/join/join.asp” to sign up for the EG card, a pop up states “Service was terminated on June 30″. Does that mean the EG card no longer exist?

    December 23, 2013 at 5:12 pm

    Hi littlemisshoo,
    I wanna ask regarding the olleh wifi on demand. If I buy for 1 day @ 3300 krw. Can I switch on and off the usage, like for instance, I wanna use the internet for 3 hours then I log out, and continue the usage for tomorrow (So I still have 21 hours internet). Does it work like that?

    • December 23, 2013 at 9:25 pm

      Hi Dalo

      The daily Wifi starts from the time you activated. Even if you off and switch on later it, the time will continue to count.

      Have a great trip in Korea!

  37. Shermaine
    December 24, 2013 at 1:34 am


    Do you know if the EG SIM card can be reused/reactivated once it has expired (i.e. I did not top up for more than 1 month and I want to use it again for my next trip to Korea a few months later)? Or do I need to purchase a new SIM card?

    Thanks and Merry Christmas!

  38. Shermaine
    December 24, 2013 at 6:55 pm


    Can you still reuse/reactivate the EG SIM card after it expires (i.e. I don’t top up for more than a month or the value is zero, and I want to use it again when I visit Korea a few months later)? Do I need to purchase a new card or can I reuse the existing card?

    Thanks and Merry Christmas!! ^^

    • December 25, 2013 at 5:22 am

      Hi Shermaine

      It expired 30 days after the last top up and at the moment you need to purchase another SIM CARD.
      You can ask EG CARD team in their FB page. They are pretty fast in replying enquires.

      Hope this helps!

    Hi Littlemisshoo,

    Thanks for your great review.

    I’ve purchased a EG Simcard and have purchased the 1Gb data package. I understand once you have activated an EG Simcard , I get free access to Olleh Wifi hotspot.

    When I’m in range of an Olleh Wifi hotspot, I would like to switch to it to save the 1Gb data on the SIM.

    However, I don’t know what information and how to log into the Olleh Wifi hotspot, would you know?

    Thank for your help!!


    • December 25, 2013 at 5:25 am

      Hi Michael

      It will auto log you into the Olleh Wifi hotspot and you dont have to enter ID and password :)

      Hope this help!

    December 27, 2013 at 8:33 pm

    Thank you for the tutorial. Do we need to have our wi-fi on to have access to the data? Because my phone wi-fi is spoilt so I cannot connect to any wi-fi. I am scared that I can’t use data after buying the sim card. If I buy sim card online and selected the 1Gb data service option (there is already 20,000 krw of sim card value), will we able to use the data immediately?

    • December 29, 2013 at 11:18 am

      hi Nabilah

      Yes we should be able to use the data plan immediately after putting in the SIM CARD

    Hi there. i just bought an EG sim card via the eg webpage. What documents do i need to bring as proof of purchase when i get to the collection point? (other than my passport)

  42. Eri
    January 30, 2014 at 1:07 am

    Hi dear! I’m Eri from Malaysia. I’m currently using Samsung Galaxy S3 ( GT – 19300) . I’m pretty sure it’s unlocked coz I can use any provider’s number on it.
    I’ll be staying in Korea for about 5 years and I plan to buy the EG card.
    The problem is I can’t use WCDMA or GSM/WCDMA ( Auto Mode) on my phone currently ( in Malaysia).
    I’ve heard that my phone is not compatible with CDMA :c Does that mean I can’t use the EGsimcard?
    I’m sorta confused coz it has HSDPA 21 Mbps / HSUPA 5.76Mbps Quad Band (850/900/1900/2100 MHz).
    and I saw on EG’s blogspot this:-

    1.1 Compatible phone
    – Most 3G wireless providers in Korea use the UMTS/HSDPA frequency of 2100 MHz.


    Oh and was there any age restrictions for purhasing the card? coz I heard of below 20 years old are prohibited bla bla bla

    Thanks in advance.

    Hi may i know how did u pay when u top up? if u choose credit card payment , they will prompt for ur credit card details? are there other methods of payment?


    • March 10, 2014 at 7:17 pm

      Hi Wei lin

      yes they will prompt you for credit card details.
      Other form on SIM CARD top up are available is selected GS25 stores.

    March 10, 2014 at 11:40 pm

    Hello! I’ll be going to Korea next month for 2 weeks and I’m so happy to find your post about this prepaid sim card :)
    I only have one question though, when the first time you bough the EG SIM Card, may I know how much did you pay? Because based on your explanation you just have 2,000 won voice amount at first, so you have to top up to start to use your 1GB data plan.
    But based on EG website, it stated that I have to pay 25,500 won (5,500 for micro sim card and 20,000 for sim card value). So If I want to use my 1GB data plan, I only have to transfer 16,500 won to Data? Or should I still have to pop up some $$ into my new EG sim card?
    So sorry for bothering you, wish you have a little time to reply my message :)
    Thank you!

    • March 11, 2014 at 4:21 am

      Hi Putri

      The intial 2000 won + free sim card cost (5,500) was a promotion when EG SIM started this.
      Now you have to pay for it.

      You can use the 20,000 SIM card value and transferred them to data plan.
      don’t transfer all cos you will need to have min amt in the SIM card.
      That is needed when you are making calls out.

      Hope this help..

      Please refer to their facebook as they offer a lot of detail explanation ^^

    My wife and I live here and we bought her a SK prepaid SIM card for 10,000 for her australian samsung. I set up her apn settings so it now looks like data should be working (the little “H” comes up now) but it won’t connect to the Internet. Is there special data top up she needs or does she need to transfer credit from talking credit to data credit? I wasn’t there when she bought it so of course I don’t have any answers. ;-)

    Hi! I’ll be staying in Korea for a year. I’m interested in the EG sim card but I really want to have internet. From the different choices you mentioned, which one do you think is better? Is it necessary to have a korean bank account in order to get the sim card?

    • April 5, 2014 at 12:41 am

      Hi Danie

      You don’t need to have a Korea Bank account to get a SIM card.
      I have internet access using EG SIM card and the KT SIM CARD

      EG SIM card is my preferred choice as it is easy to top up and check balance :)

    April 16, 2014 at 12:03 am

    Hi, I don’t understand. For the EG SIM Card, after I have collected the SIM card from K Books and insert into my phone, do I get internet access right away ?

    If not, how do I purchase the top up data plan when I don’t have internet access?

    • April 17, 2014 at 5:08 am

      Hi Joanna

      if you have place order from online and get it collect from K Books, you must have pre loaded amount in your card.
      If you bought your card from GS25 store, you can choose pre load amount.

      You will need at least wifi to get internet for top up.

      Hope this helps

    Hi Littlemisshoo,

    I am travelling to Korea soon and need your advice on whether i can enable personal hotspot when using EG sim card? Im using iphone 4s & i called the apple store, the helpdesk informed that for prepaid card, some network carriers have personal hotspot while some dont. He advised that EG sim card does not support personal hotspot, only olleh and SK telecom. Can i confirm this with you?

    Appreciate your help. Thanks in advance

    I’ll be in Seoul for a week in May and am looking for a prepaid SIM with a data plan. From the earlier conversation between you and Travelgal, I understand that the EG SIM does not support personal hotspots :(

    As I would (very much!) need to hook up both my iPhone 5s and iPad, are there any alternatives you could recommend?

    Thanks in advance!

    • May 2, 2014 at 3:46 pm

    Did you buy or rent the olleh simcard? Can we buy the simcard instead of rent it?
    And can we pay with cash? :)

    • May 2, 2014 at 3:45 pm

      Hi Cecilia

      I bought the simcard :).
      if you wish to pay by cash, you will have to buy from GS25 store in the airport.

    Hi i am aware that the sim card expire after 30 days. But I top up again before the expiry date will it be extended? (I will be staying in korea for more than 1 month hence need to confirm abt this information).
    Plus, the data plan I selected will also expired after 30 days. How about the value available in voice? Will it expire after 30 days too?

    • June 12, 2014 at 4:04 am

      Hi SN

      It will be extend for another 30days once you top up before the expire date.
      From my understanding, yes the $$ will be expired too.

    Hi!! if we order the Eg sim card (nano) before going over, do we still have to cut the sim card ourselves? Will the staff help us to activate when we reach?

    Thank you so much!

    • June 12, 2014 at 4:03 am

      Hi Vanessa

      Yes you can request the staff to activate for you once you get your SIM card.
      My sister didn’t do the test and later found out the SIM card is faulty.
      To exchange for a new SIM card she had to visit their office in Seoul Station.

      It’s better to buy the SIM card online before you depart for Korea.
      You can also buy the SIM card at convenience store located around to K-Book store. Subject to availability.

    Just want to confirm that when we select the data plan when we order online it automatically comes with it? Eg. selecting 1GB means i get 1gb on the EG sim when i go to pick up?
