Easy to setup
Easy to setup. Service was always there when I needed it. Saved a bunch of money from what my carrier would’ve charged had I used their international plan.

I travel to Europe
I travel to Europe at least annually and used a competitor many times before. Noticed Ubigi to be much more competitive price wise - and installation was a breeze, much easier than with the competition, I could not believe the ease! Really great experience ~ thank you for making this so straight forward! The app is very user friendly also.
