App is only available in German, which is fine, but as a sim card management app, it blocks screenshots for no reason so I can't even translate anything on the app. User interface seems ok though if you can learn a language to technical accuracy first.

WinSim is one mistake I would like to avoid a repeat at all cost. Since moving to Germany and getting winSim at home and handy, I have experienced it all...From poor network service provision, to poor customer service provision especially if you are a non german speaker, to hidden charges and fluctuation in charges and you can expect that the charges will always go higher than that on their eye catching advertisement. I can go on and on. It is a shame I have to put up with them for two years.
