Totall mess, thats all i can say. Edit, now they added limitation on ussage in roaming, making complete experience even worse. And apparently app is counting only 300 MB as allowed outside Germany. And by restrictions, i mean i cant use complete internet volumen outside Germany, even if i have roaming plus active Not to mention absence of English (AT LEAST) language in app Slow, unlogical, unpractical All in all, im just so sad im tied with a contract, and too bussy to go to see my lawyer.

Hi Miroslav Momirovic, thanks for your review. What exactly do you mean by usage restrictions?

Not all functions are available in an User Friendly speaker of a multicultural native language. e.g I would find this app less irritating if all functions were available in English. Unbelievable that even after several years, that this App is still not available e.g. in the English Language

This is the most stupid app. How hard it must be to give English as an optional language in this age of AI? 24% of population has immigrant background. You can't even use Lens to translate anything since this stupid app won't let you take a screenshot. Leaving this comment before porting to a half decent service provider. And the service sucks outside main city anyways.

Hi furqan yousafzai, thank you for your review. We can understand your wish for an English version. We don't have a solution for you in the short term, but in the long term we will also offer an English version of the app.
