Easy to install. Convenient to use. Good signal. Works well even in many places. There is a link to check how much you have used. Recommended. No need to put in a SIM card, it's a hassle.

The internet is okay, but the signal is weak in some areas in Kyoto. We bought 2GB per day, but it wasn't enough. Every day, it runs out at 5 PM. After it runs out, it's incredibly slow, making it almost impossible to do anything. If you're using it a lot to browse maps, use Instagram or TikTok, I recommend 5GB per day. It's better to have some extra than not enough, because it can be really difficult to search without internet.

I went to Vietnam → Cambodia on a woman's solo trip and stayed in Cambodia for 9 nights (Phnom Penh 2 nights, Krache 1 night, Siem Reap 6 nights) ♪ Thanks to this eSIM, it was a fulfilling trip ^ ^ Use again Shu!

Reviews: [Japan] Mobile WiFi Rental-Pick-up/Return at Airport

Guest User2025-12-26

It worked flawlessly: the charge lasted all day, and I had a connection everywhere. The only downside was that it took a long time to charge. I'm very pleased!
