Dutch only. They try to rip you off if you exceed the data plan Reply to Developer Response - By “Dutch only”, I meant that the app (as well as the website and email communication) are only in the Dutch language. There is no English option. - The plafond starts at ~10€, which means that there are, in fact, extra costs if I exceed the minimum plan of ~2€. The service is riddled with tricks and traps to squeeze extra money from clients such as the plafond toggle being off by default or even being necessary.
