Kimchi University Group SIM Korea: International Student and Cohort Mobile
For university international offices, exchange program coordinators, and language program admins in Korea, group mobile setup turns the first week of arrival from a SIM-shop scavenger hunt into a single workflow. Whether you are bringing in 20 international students for a semester or 200 for a year, Kimchi Mobile B2B handles the SIM and eSIM side.
Why universities choose a group SIM workflow
- International student arrivals: degree-seeking, exchange, summer program, and language program students need data and a Korean number from day one.
- Cohort orientation: consistent connectivity across the cohort makes orientation logistics easier (campus tours, group chats, banking sign-ups).
- Visiting faculty and researchers: short stays and sabbatical visits need a clean SIM solution that matches the duration.
- Multi-year residence path: students staying past one semester move into the ARC pathway and postpaid plans for the rest of their program.
The student arrival workflow
- The international office shares cohort details (size, arrival dates, program duration) with Kimchi Mobile.
- eSIM QR codes are emailed to each student or to the office for distribution.
- Students install the eSIM before flying using home Wi-Fi.
- On arrival in Korea, students activate the line and have data ready for orientation, KakaoTalk, banking, and food delivery apps.
- For programs lasting past one semester, students transition to a postpaid plan after their ARC is issued.

- Korea Starter SIM, same shape, common for general residents
For language and short-stay programs
Language schools (Korean language institutes) and short summer programs often run 1 to 3 months. For these durations, prepaid eSIM bundles aligned to the program length are simpler than postpaid because they do not need an ARC, a Korean bank account, or a 12-month contract.
For degree programs and exchange semesters
Year-long and multi-semester programs benefit from the 60-day prepaid plus 12-month postpaid transition. The Korean 010 number assigned at the prepaid stage can carry over to the postpaid plan, so the student does not have to update KakaoTalk, banking, or campus directory listings mid-year.
Frequently asked questions for international offices
Yes. The international office can pay for the initial prepaid window centrally, and each student handles the postpaid renewal independently if the program continues. Billing is set during the quote.
Most modern unlocked phones from 2018 or later support eSIM. Apple lists iPhone XS, iPhone XS Max, iPhone XR, and later as eSIM-capable. Android phones vary by manufacturer. For phones without eSIM support, physical SIM cards can be coordinated.
A Korean bank account is needed for postpaid plan autopay, not for prepaid plans. Most students open a Korean bank account during orientation after their ARC arrives, which aligns with the postpaid transition timing.
Yes. Short-stay faculty often use the data-only eSIM plans that match their visit length, while year-long visiting faculty often follow the same prepaid-to-postpaid path as students.
eSIM QR codes can be emailed directly to each student, sent to a single office mailbox for forwarding, or printed on welcome packet sheets. Kimchi Mobile coordinates the distribution method during the quote process.
Prepaid plans simply expire after their duration, so leaving early is a clean exit. For postpaid plans, the cancellation rules follow the carrier and contract terms, and the account manager helps coordinate.
