FAQ

▸Is pocket WiFi or eSIM cheaper for Japan?

For one or two people, an eSIM is almost always cheaper. For a group of three or more sharing one connection, a single pocket WiFi router can work out cheaper per person.

▸Can a pocket WiFi connect multiple phones?

Yes — that's its main advantage. One router typically connects 5–10 devices, ideal for families and groups travelling together.

▸What's the catch with pocket WiFi?

It's another device to carry and charge, you must return it, and if it runs out of battery everyone loses connection. An eSIM lives in your phone with nothing to return.
