Install took me two tries but was fine after that. Setup instructions in the app were clear and simple.

Worked fine but took a little while to connect at first. Ran hotspot to my laptop with no issues.

Frequently asked questions

How much does the Japan eSIM cost?

The Japan 10GB 30Days (IIJ) plan costs $7.05 for 10 GB over 30 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?
