The short answer
A data SIM, a Korean phone line and identity verification are different services. Ask the carrier and bank which identity documents they currently accept for your status.
Who this is for
Students setting up everyday services
Follow these steps
- Separate immediate data access from long-term phone identity needs.
- Confirm accepted identity documents with the provider.
- Keep the same legal name format across immigration, phone and bank records.
If something goes wrong
- Identity verification failed — compare the legal name and birth date across immigration, phone and bank records.
- The legal name does not match — use the passport spelling and order everywhere.
- Account opening was declined — ask the bank which documents it accepts for your status.
