Ubigi app was easy to use and a fraction of the cost for international cell phone service!
We used the Ubigi app for our trip to Korea and Japan (we live in the U.S.) and it was a fraction of the cost to use our phones abroad (in comparison with how much we would have paid through our regular phone carrier with international calls add on service). We will be using Ubigi for all our travels abroad going forward! Highly recommend it!

Overall solid, a few rough spots
Data kept cutting out in certain spots, even with clear access, outside with no clouds. Only solution was to completely reset phone to reconnect automatically

Great when it works, app can be a bit slow when checking data.
Fantastic rates and value during a trip to Japan. Generally well connected throughout Osaka, Kyoto and Tokyo. My only issue is that the Ubigi app itself is quite slow and a bit clunky, also having to log in every time I want to see my data allowance. Sometimes I think I've run out of data in the middle of my trip, when in fact it's just really slow.
It would be nice if they sent a notification or SMS that I was on my last GB of data or something, or not require logging in every time.
