🇰🇷 South Korea
Busan eSIM
Land in Busan, scan a QR, and you're online on a local network in seconds. No daily roaming fee, no surprise bill. $1.40 per GB.
Data in Busan
In Busan the eSIM rides KT and SK Telecom with 5G typically available - the same towers local subscribers use, selected automatically by signal strength. City centers, transit, and airports are the strongest coverage any network offers, so this is the easy case. Some of the fastest mobile data on Earth, underground metro included. No practical coverage gaps.
Pricing is South Korea's flat rate of $1.40/GB, metered per MB from a prepaid USD balance. A city break runs light: maps, ride-hailing, translation, and messaging together use well under 500 MB a day for most travelers, so $10 (≈ 7.1 GB) commonly outlasts the trip - and whatever's left keeps working in the next city, or next year.
Arrival checklist
- 1. Install the eSIM on Wi-Fi before you fly (QR or one-tap iPhone install).
- 2. Turn Data Roaming ON for the Anon eSIM line; leave it off on your home SIM.
- 3. Set Anon eSIM as the mobile data line; keep calls/SMS on your primary.
- 4. Land in Busan, drop airplane mode, and you're connected within a minute.
No ID, no account, no email - $5 minimum plus a one-time $5 setup fee for a new eSIM. Top-ups later are fee-free.
