Japan eSIM — FAQ
How do I get an eSIM for Japan?
Pick a Japan data plan below, pay with Apple Pay, Google Pay or card, and we deliver your eSIM instantly. Scan the QR code and you're connected in minutes — no physical SIM, no store visit.
Will my phone work with a Japan eSIM?
Most phones from the last few years support eSIM, including iPhone XS and newer, Google Pixel 3+, and recent Samsung Galaxy S/Z models. Your phone must be carrier-unlocked.
Does the Japan eSIM include 5G?
Yes — our Japan plans connect to 5G where the local network supports it, and fall back to 4G/LTE automatically.
Can I keep my own phone number?
Yes. The eSIM runs as a separate data line, so you keep your main number for calls and texts while using Japan data on the eSIM.
When does my plan start?
Your validity begins when the eSIM first connects to a network in Japan, so you can install it before you travel and it won't start counting down until you arrive.
