🇰🇷 South Korea
South Korea eSIM for digital nomads
Staying in South Korea for a month or a season changes the maths. You need enough data to work, you may not have a local address to register a SIM against, and you probably do not want a contract tied to a country you will leave in eight weeks.
A pay-as-you-go balance at $2.70 per GB covers the working days and stops costing anything on the days you are on cafe wifi.
Working coverage, not just tourist coverage
Heavy map, messaging and video use. Expect 8 to 14 GB over two weeks.
Partner networks are SK Telecom, KT, so a coworking day in Seoul and a weekend outside the city both sit on infrastructure built for residents rather than a thin visitor roaming agreement.
No address, no registration, no problem
Buying a local prepaid SIM in South Korea means presenting ID and having your details recorded against the number. An eSIM issued outside the country skips that process entirely.
Long-stay visitors get caught by this more than tourists do, because the postpaid plans with sensible pricing usually require residency, a local bank account or a tax number. A prepaid eSIM sidesteps the entire requirement.

Practical tips
- Treat the eSIM as your backup to apartment wifi, which fails more often than the mobile network
- Auto refill at a low threshold avoids being cut off during a client call
- Use a hotspot for the laptop on travel days between Seoul, Busan, Jeju
- Keep the recovery token in your password manager, not only on the phone you travel with
