The short version
Most people get stuck at identity verification. With an Alien Registration Card it is much smoother, and without one yet, a prepaid SIM that works on a passport is usually the faster first step.

Step by step
- 1
Decide first: do you need a number now, or a long-term plan
If you just need a number for text verification, a prepaid SIM is fast. If you will use it for a while, look at a long-term plan. Different goals need different things.

Look for a prepaid or budget carrier that works on a passport
- Where:
- Airport, convenience store, budget carrier shops
There are options that activate on a passport even without an Alien Registration Card. Conditions vary by shop, so ask around until you find one that works.

Move to a long-term plan once your Alien Registration Card arrives
With the card, identity verification is easier and your options widen. If you want to keep your existing number, ask whether a number transfer is possible.

Connect this number to the services that require identity verification
Banking, delivery and quick pay often verify you with a Korean number. Once you have one, those doors open together.

Easy to miss
- A passport activation can go through, then some apps block you again at their own identity check.
- Shops describe foreigner activation rules differently, so giving up after one shop can cost you.
You can skip this if
- If you are here for a few days of travel, a data-only SIM or roaming may be enough.
When it is time for a person
- If carriers and shops keep telling you different things and you stay stuck, it may be time for a person who can help with settling in more broadly.
