Good Priced and Reliable Service
Ubigi was reasonably priced and easy to set up. As soon as we landed in Japan we had available data. Their network never let me down and internet speed was great!!!

We used the Esim in Japan
We used the Esim in Japan, throughout Tokyo and Nagano covering Yamanouchi(city closest to the snow monkeys) and Matsumoto. Throughout the trip, I had consistent coverage majority of the time having 5g coverage. Having that coverage definitely inspires some confidence when traveling and a service with no hiccups is always great when you're abroad. Thanks Ubigi, we'll be using this service again!

Great Experience with Ubigi
The experience is great. The connection was stable, the eSIM setup worked flawlessly right from my phone. Overall, Ubigi offered a hassle-free solution for staying connected abroad. Highly recommended for travelers.

The Africa regional eSIM was ideal for me
The Africa regional eSIM was ideal for my three-country visit.
While I HATE talking to AI support bots, I confess this one was extremely helpful in diagnosing one problem on my phone configuration when I landed in South Africa.
It was also trivially easy to top up using Apple Pay.
