Frequently asked questions
How much does the Japan eSIM cost?
The Japan 10GB/Day plan costs $8.00 for 10 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.
