Will definitely recommend to anyone travelling through Europe
I have used other esims before which all had reliability and speed issues. In fact Ubigi was therefor surprisingly easy to install and the connection speed was perfect for our needs.

It was so simple and easy to use
It was so simple and easy to use. We watched a very short video on how to turn it on before we left and we’re able to do so from the tarmac at the airport in Japan and it worked everywhere. We went on our trip from Tokyo to Hakone, then Kyoto and Osaka.
