Phones, transit, and daily errands

Not official advice. Carrier plans and bank KYC rules change. Ask the counter for the current foreigner checklist.

Mobile

• Prepaid SIMs and eSIMs are common for short stays.
• Long-term plans may need ARC and a local account.

Transit

• Load a transit card at convenience stores or station machines.
• Buses and metro announce major stops in Korean (and often English on key lines).

Banks & cash

• Many places take cards; small shops may prefer cash or local pay apps.
• Opening an account usually needs residence status and documents—ask the bank’s foreigner desk.

Official / practical links

• Korea Tourism Organization
• Local city hall / district office pages for residence notices

Tip

Screenshot your card balance and keep a small cash cushion for markets and late-night taxis.
