Frequently asked questions
How much does the Japan eSIM cost?
The Japan 3GB/Day plan costs $3.74 for 3 GB/day over 1 days, paid once with no hidden fees.
How do I activate my Japan eSIM?
Scan the QR code in your phone settings (Cellular/Mobile → Add eSIM) or tap Install in the GotoeSIM app. Install on Wi-Fi before your trip; it activates when you arrive in Japan.
Will this eSIM work on my phone?
It works on any eSIM-compatible, carrier-unlocked phone — iPhone XS and newer, Google Pixel 3 and newer, and recent Samsung Galaxy models.

Comments & questions
Haruto W. · 1 month ago
Does it work on an Android phone from 2021?
Hi Haruto! It should — most Android phones from 2021 are eSIM-compatible, though it does need to be carrier-unlocked. If you tell me the exact model I can double-check, or reach us at gotoesim.com/support. – Yuki
Mei T. · 2 months ago
Can I buy it now and activate it later?
Absolutely, Mei — installation and activation are separate. Buy now and scan the QR code whenever you like; the Japan plan only starts counting once you first connect in Japan. Need a hand? gotoesim.com/support. – Grace

Is 5G supported or just 4G?
5G is available where covered, Elena — you'll always get the best speed on offer. — Priya, GotoeSIM Support
