Frequently asked questions
How much does the Japan eSIM cost?
The Japan 5GB/Day plan costs $6.60 for 5 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 eSIM TopUp 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.
Can I keep my regular number?
Yes. The eSIM runs alongside your normal SIM, so you keep your number for calls and texts while using data in Japan.
