Japan eSIM — FAQ
Do I need an eSIM for Japan?
If you want mobile data in Japan without paying expensive roaming fees, a travel eSIM is the easiest option. You install it before you leave and it connects automatically when you arrive.
Will my phone work with a Japan eSIM?
Yes, as long as your phone is eSIM-capable and carrier-unlocked. Most phones from 2018 onward qualify (iPhone XR/XS and newer, recent Samsung Galaxy and Google Pixel). Dial *#06# — if you see an EID, you're good to go.
When does my Japan eSIM start?
Your validity period begins the first time the eSIM connects to a network in Japan, not when you buy it. Install it before you travel and it activates on arrival.
Can I keep my phone number in Japan?
Yes. The eSIM runs alongside your normal SIM and is data-only, so you keep your home number for calls and texts while using Turkey Esim's eSIM for data in Japan.
