Traveling from UK to Japan with Ubigi

As soon as I landed in Japan Ubigi was up and running and I didn’t have to worry about using my phone abroad. Thank you so much for the peace of mind this gave me.

Easy to use

It’s really easy to use and not expensive. The only problem is I sometime experienced short connectivity issues in big cities in Japon. Maybe that could be improved

Good signal and easy

Ubigi works!

We bought Ubigi for the first time for our Japan trip; I have to be honest, i was impressed it worked all the time! We were very happy with the service, never had issues on the subway, Shinkansen or even on the mountain of Kyoto of the monkey park! It would get signal everywhere!! The only time it slowed down was in the basement floor 2 while I was in the bathroom, but no issues anywhere else!

Ubigi surpassed my expectations

Ubigi surpassed my expectations. I used it in Japan and South Korea and the signal was great. I had high speed internet the whole time. It was my first time using it, and what I enjoyed the most about Ubigi is that I didn't need to install a new eSIM when I got to a different country. I kept the same eSIM, and I just change the plan on the Ubigi App. I feel this is such a great feature that is not advertised enough.

good connection but bad compatibility test

good connection. however it said my iphone is sim-locked after arrival although i did the compatibility test successfully from my home country. turns out i had to take out the sim card from my home country.

Very easy to use
