I was lucky to get participated in the closed testing procedure of CwSim and I am happy incredibly to say that I don’t need to think about the expenses for the mobile Internet in roaming anymore. Generally, it’s comfortable to use the app to manage operations, you’re connected to an operator in few seconds and you’re always online!

It’s a very simple device to use that provides the mobile Internet access to everybody in European Union for just 2 rubles for MB!

Excellent device that really helps me a lot in my trips. Now I don’t have any head concerns about where to take the mobile Internet from, and that’s awesome.
