If your upcoming visit to Korea requires a prepaid SIM card for calls, texts, and internet, you can easily purchase one that’s enabled for all these services. We always buy the KT Olleh prepaid SIM, which offers plans for 5, 10, and 30 days. (If you think you’ll get by with just a data SIM card like most tourists in Korea, you can choose the KT Olleh data SIM card option here.)

Here’s how you can buy the KT Olleh prepaid and data SIM card in Korea:

  1. View their product listing here and find the ones that are tagged ‘Calls and Texts Included’

  2. Select between the 5, 10, or 30 day option.

  3. Complete your purchase of the Korea SIM card.

  4. Keep a copy of the online voucher.

  5. Easily claim your prepaid Korea SIM card in any of the redemption booths listed below.

  6. Activate and top up.

When your pre-loaded credits are consumed during your stay (or if you booked one that was not pre-loaded), you can load up your prepaid SIM card in Korea with an amount of ₩11,000-₩55,000 (around ₱515-2,575 or $10-50). This can be done in any convenience store, such as 7-Eleven, CU, or Mini Stop. A top-up of ₩11,000 is roughly equivalent to 41 minutes of domestic calls (within Korea), 100 domestic text messages, or 33 International text messages. You can check out the actual rates for each text or call here.

If you need to extend the validity of your prepaid Korea SIM card, you can do so here. Do note that the amount paid for extension will be non-refundable
