In South Korea, it is obvious that major two SIM products from kt (Korea Telecom) have monopoly on the entire SIM market now. 4G LTE Prepaid SIM is available all around the airport and you can see everywhere including CVS. Moreover, Unlimited Data SIM is the most popular SIM plan.

The minimum price for recharge is KRW 10,000 per 500MB. I think it is not that cheap, but it is totally worth for its world top class premium quality. For this reason, I would like to strongly recommend 2GB SIM instead of 1GB, if you need more than 1GB. This way, you can save KRW 5,000 with the same value of 2GB.

Recharge Online with easy payment

Available at all time and easy to recharge. No need to face language barrier in front of your eyes. Simply enough with paypal or your credit card.

Just visit https://www.krsim.net/product/additional-top-up/20/ and order. That’s it. This is a part of Korea SIM Card web page(https://www.krsim.net).

But if you want to recharge during weekend or at night, it is hard to recommend because the recharge will be activated as of the next working day. However, it enables to recharge real time during operating hours in weekdays.

Recharge in CVS in real time

Or you can also recharge at any convenience stores in South Korea such as 7-Eleven, GS25 and CU nationwide 24/7. It is truly real time recharge.

7-Eleven and GS25 have easier way whick you can simply show your phone number of the SIM and pay the desired amounts to recharge. All the credit cards are available for payment. You might experience language barrier but in that case, you can show the note below to the reception staff.

Otherwise, CU has PIN code-based top up system. (customer top-up on their own) Once the staff is done processing, you will get a receipt with PIN codes printed (11 digits). Then call 080-013-0114 (for free of charge) and follow the message on the line. English instruction will be provided.

When recharge is finished, you will receive notification message in real time.

How to Check Credit Balance

Call ARS 080-012-0114 (for free of charge). Then you will receive SMS that contains the information of the remaining credit balance.

Or, you can call 080-770-0114 and ask the staff there. They will let you know the credit balance.
