Staying connected: eSIM, SIM, or pocket WiFi?

Step by step

1. 01

   eSIM (recommended)

   On a supported phone, set it up with a QR code before you leave and it works the moment you land. Easiest for solo travelers.

2. 02

   Pocket WiFi

   For groups or multiple devices. Pick up/return at the airport or have it mailed. You carry the device and its battery.

3. 03

   Physical SIM

   Sold at airport counters, but often pricier than an eSIM, and you swap your SIM.

4. 04

   Free WiFi

   Available at konbini, stations, and cafes, but unreliable — don't rely on it as your main connection.
