Signal and connection is consistent. That is number 1.

Easy to install and check your data usage.
Good price for what I needed. Easy to install and check your usage amounts with out having to log in all the time. Easy to identify e-sim on the phone without having to rename it.

The first choice e-Sim for Japan!
Simple to buy and use, with a very competitive price. For Japan (our chosen region) there is no other choice.

Worked great
Went to Costa Rica for 12 days and purchased a 30 day 10 gb package. We used it everyday for Waze maps, whats app and a few messages and pictures to home. Only used 1.5 gb the entire trip. It worked 95% of the time except for when we were on a country road in the middle of nowhere but it didn't take long to connect again. Will be using again. Too bad the referral code is only good for 8 months as I don't travel that often.

Easy, Useful and Connective
It was easy to access the app and the website. It was ok to buy the esim needed. However, it was a little confusing to understand types of payment accepted and also there was too much information in one page altogether. It was a very good experience and I was able to use the esim almost all over Japan which was amazing. I recommend tremendously!

Great data service in Japan
Great data service in Japan. It worked fast; it was reliable & affordable. Worked way better than the Verizon travel pass BS. I’m gonna use Ubigi data e-sim all the time when I’m overseas now!
