Reviews: Japan 4G/5G eSIM 1-30 days High-speed data Daily package/Data package Optional days (calendar day) QR code
Guest User2025-10-19
I purchased this eSIM for my recent trip to Japan, and it worked flawlessly from the moment I activated it. The setup was super simple, and the connection was fast and stable everywhere I went – Tokyo, Kyoto, and Osaka. I never had to worry about finding Wi-Fi or dealing with physical SIM cards. The data speed was impressive, and I could easily use Google Maps, translation apps, and stay connected with friends. Highly recommend this eSIM for anyone traveling to Japan!

Good and eaay to the signal is mostly, 95% of the time, stable. The food thing is that then it requires no roaming at all since it is a local e-sim.

Coming to Japan alone is comfortable. No need to worry about communication. The signal is good, no cuts. Plus, you can watch many series. Calling the hotel, the signal is good. It's very good. Normally, I use roaming, so the internet runs out very quickly.

Reviews: Asia 9 Destinations 5G eSIM | Japan, Thailand, Vietnam, Indonesia, Korea & More | 1–30 Days | Instant QR
Guest User2025-09-02
This is my second purchase. The signal is strong even in Shangri-La, and I've been able to use it without any problems. I'm going to Kunming-Korea next, so if it works as well as last time, it will be perfect. It's very convenient to be able to use it in other countries without changing the settings. I'll definitely use it again.
