Solid overall, just wish there was a bit more data for the price. Signal held up well on trains and in rural areas.

How much does the Japan eSIM cost?
The Japan 3GB 30Days (nonhkip) plan costs $4.72 for 3 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 GotoeSIM app. Install on Wi-Fi before your trip; it activates when you arrive in Japan.
