eSIM vs pocket Wi-Fi in Japan and Korea: which is better for travel?
2026-11-03 · goAFK
Short answer
- An eSIM lives in your phone: nothing to pick up, charge or return, and it works from the moment you land.
- Pocket Wi-Fi suits a group sharing one connection or a phone without eSIM support, at the cost of carrying and charging a device.
- Japan 10 GB for 30 days costs $28.04 as an eSIM; South Korea 10 GB for 30 days costs $17.34.
