Korea Starter SIM: 60-Day 60GB Data + Switch to 12-Month Postpaid Deal

We are pleased to introduce a special SIM/eSIM promotion, designed specifically for foreigners arriving in Korea. This offer, provided in partnership with KT, a Korean telecom provider (KT), ensures every newcomer—especially those coming to Korea as an ESL Teacher, EPIK Teacher, or anyone holding E-series work visas and planning to stay and work in Korea long-term (over 12 months)—enjoys seamless mobile data connectivity and internet access from day one.

This plan is ideal for teachers, international employees, job seekers, and anyone who needs reliable connectivity for an extended stay in Korea.

The standard, year-round bridge. This is our ongoing, non-promotional 60-day data eSIM → KT postpaid bridge — the everyday alternative to the limited-edition Welcome SIM. Choose this one if you are not eligible for that anniversary offer, or once the Welcome SIM promotion ends after 2026.

Honest answers

Questions about this plan

Does this include a real Korean phone number?
Not on arrival. You land on 60GB of data for up to 60 days. Your real Korean 010 number — the one that receives the SMS codes Korean apps need, like KakaoTalk, banking and 본인인증 (identity verification) — is issued when you convert to a KT postpaid plan with your physical Residence Card (ARC). This plan is for long-stay and long-term-visa holders; short-stay visitors should choose a data-only eSIM. Not sure your visa qualifies? Ask KIMO before you buy.
Do I need an Alien Registration Card (ARC) to get the number?
Yes. The data period runs on your passport, but your real Korean number is only issued when you switch to KT postpaid, and that needs your physical Alien Registration Card (ARC) plus a Korean bank account or card. The ARC takes about 2–3 weeks after you arrive, and the registration-fact certificate is not accepted yet — only the physical card.
Which phones work with a Korea eSIM?
Most recent unlocked phones support eSIM — iPhone XS and newer, Google Pixel 3 and newer, and Samsung Galaxy S20 and newer. Your phone must be carrier-unlocked. Phones bought in mainland China or Hong Kong may not support eSIM.
Can I get a refund?
Yes — you can request a refund any time before you install or activate. If a QR code cannot be delivered or activated due to a service fault, email [email protected] for a resolution.
