Which one is you?
1I only have a passport (no ARC yet)You can get a prepaid SIM the same day. Bring your passport. You top up monthly. When your ARC arrives, the number can be moved to your name and, if you like, switched to a monthly plan.
2I have an ARC and 6+ months left on my stayYou can sign up for a monthly (postpaid) plan like Koreans do. Bring passport + ARC. The contract runs within your permitted stay. Bring your own unlocked phone or buy one outright.
3Less than 60 days left on my stayCarriers do not allow a monthly plan in this case. You can use a prepaid SIM now, and switch to a monthly plan after your stay is extended.
What to bring
- Passport (everyone)
- Alien Registration Card (ARC) — for a monthly plan or to move a prepaid number to your name
- A Korean bank account or credit card for monthly billing (monthly plan only)
- Your phone, if you already have one — it must be unlocked

Common questions
- Q. Can I get a SIM with only a passport?
A. Yes — a prepaid SIM, the same day, at a partner store. An ARC is needed only for a monthly plan or to move the prepaid number to your name. - Q. Can I use my own phone?
A. Yes, if it is unlocked. Bring it to the store and the SIM is activated in it. - Q. How do I top up a prepaid SIM?
A. Monthly, by card or bank transfer using the carrier’s top-up methods explained at activation. Keep topping up on time, or the number is cancelled after the grace period. - Q. My ARC arrived. What now?
A. Visit the store: the prepaid number can be moved to your name, or switched to a monthly plan if you have 6+ months left. - Q. Is there any fee for applying?
A. No. You pay only the plan fee at the store.
