I was using Ubigi for the first time. This eSIM was really easy to install and to use during my stay in Japan. This was such a breeze compared to another eSIM option I have used in the past. I will certainly use Ubigi again during my upcoming travel to Europe.

Connection is slow half of the times
Connection is slow half of the times, this is somehow different than last time I used Ubigi. The only difference is I got the unlimited package this time vs. 10GB last time. My wife uses 10GB without any issues either. If you are throttling the speed of the unlimited package, what's the point of paying more to get less?

Most reliable esim
I used Ubigi eSIM for the first time while I was traveling in Japan (Tokyo and Osaka) recently. It was very easy to install and amazingly it worked so well throughout my journey without any connection issue at all. I am thinking of using it again soon in my next travel destination.

Highly recommended if travelling beyond the usual city destinations
Easy to connect, and good connection across Tokyo, Atami, Yamanakako and Nagoya. While it's not the cheapest option available, it's certainly NTT Docomo (some market as that but are not).

Good connection and value
Choosing Ubigi helped me in what I needed and for a good value. I didn't had issues with connection and the tutorial was helpful. Thank you very much.

Easy to use and install
Easy to install and navigate through the app.
Good value.
It was helpful to receive instructions on how to set up my phone so I could move from my Primary Sim to Ubigi.
