Japan - Connectivity

Some say it's easier to get a "pocket WiFi" than an eSIM. One can arrange for the pocket WiFi before landing and pick it up on arrival.

eSIM / Data

• eSIM is the cleanest solution (according to ChatGPT)
• You rarely need voice service. You can use VOIP (voice calling in Signal, WhatsApp, etc) in place of voice service.
• Video about eSIMs in Japan
• Checking if mobile device supports eSIM
