Frictionless Mobile Data Experience in Tokyo, Japan
Signing up for an eSIM card for my wife and I during our Japan Vacation was a delight. Easy, fast, and most importantly of all, our data connection was fast (No Speed Tests were conducted but per our perception it was comparable tp our local speeds in the US.)

Recommended ... Ubigi is easy to use!
Recommended to my friends as Ubigi is easy to use!
Ubigi instructions are helpful. I had not used it for almost a year and it was seamless to re-up the service and use it again!!

A very affordable and reliable eSIM provider
Setting up the account went well without any issues, good app, works well. Ubigi eSIM is a very good alternative, to buying a data add-on from my phone company while traveling in the US ( is about 10 times less expensive). Internet connection worked well even in a remote location where previously I didn't have network signal.

I initially had problems connecting
I initially had problems connecting. It was probably more of an issue of not following the setup steps prior to my departure. Upon successfully connecting, worked like a charm

I needed an eSim service for a trip to Russia
I needed an eSim service for a trip to Russia and companies I previously used did not offer the service due to limitations imposed by local authorities on activation of Telco services. Ubigi offered the service adhering to the regulations and worked well giving me the chance to stay connected.

So far, so good.
Way to early for me to give a review, but so far, so good. No complaints other than my own bumbling in the set-,up.
