Good to know in Japan
Install the eSIM before leaving airport Wi-Fi and keep data roaming enabled for the travel line. Japan's dense rail network includes tunnels and underground sections, so a brief hand-off or signal drop does not necessarily mean the plan failed.

When should I install an eSIM for Japan?
