Very good experience but I wish I knew before that some other providers offers a wider network coverage, ex.: in between big cities.

UBIGI esim is easy
UBIGI esim is easy, affordable and useful during travel abroads. However, there are times that the connection is slow and poor. But still i find UBIGI very useful and will still recommend it.

Excellent Performance and Reliabilty for a 2 week trip
I just got back from two weeks in Japan (Tokyo, Hakone, Kyoto and Osaka). I used the 15 day unlimited plan for my trip and it worked perfectly! I first downloaded the Ubigi app on my Samsung phone, which was easier to use than the website, and had the Esim ready to go before leaving. Then, as soon as we landed in Tokyo, I activated it- I got perfect service right away! I still used wifi where I could (mostly at our hotels) to avoid using large amounts of data, but I always had access to Google maps, Google translate, Youtube, Photos, & web browsing throughout my entire trip. The speeds on my phone were better than my partner's T mobile plan, so we ended up using my phone for almost everything. Overall, I had an exceptional experience with this E sim and would recommend it for its performance & reliability. I would also recommend using the Ubigi app for an easier installation process.
