I used the app during my recent trip to Europe and am not exactly trilled. The idea is great, but it doesn’t quite work as it is supposed to. It did connect to the new country’s network many times, but then it wouldn’t on many other times. I’ve restarted my phone countless times. Their data is quite expensive and in my case went on getting sucked up by something until I had to purchase more. I couldn’t figure out where that data was going (I’m an experienced user, have spent many months in South America tracking every bit of data, using different provider). In way too many cases the phone connection wouldn’t work both ways and that was the reason to go with this service in the first place. If I wanted mobile data only there’s much better options out there. And on the top of it, they kept charging me for the forwarding number long after I came back home. As others have pointed out they do seem to be sneaky about their charges. Ah, and going back to the home network was a hassle too. Thought at some point will have to go and buy a new SIM card...
I don’t think I’ll be using that service again. Not recommended.

It doesn’t work. It has way too many steps to follow and it just doesn’t work. The so called 24/7 WhatsApp support is unresponsive.

In principle, their product is a great deal and a cool concept. In action, it took HOURS after landing in NewYork for the SIM to be recognized. After 1 day, 17$ dollars disappeared from my account because no package kicked in. Service was basically not working for the following days because « location not recognized ». I ended up buying a T-Mobile travelers SIM, which I should have done in the first place.
