FAQ

Does a Japan eSIM require passport registration?

Data-only travel eSIMs don't; only local SIMs with a phone number require residency status or passport registration.

Is the network stable on the Shinkansen?

Coverage along the Tokaido/Tohoku lines is good; brief dropouts in tunnels — avoid video calls through mountain sections.

Is there signal in the subway?

Tokyo and Osaka subways have full 4G/5G on platforms and in cars.
