Complete rubbish. Just like the service. Never works. No translate option. Password must have 30 characters and 20 different symbols. Set a new password copy and pasted and it still didn't work. Trash.

After spending a lot of time going through every menu and setting, I failed to find how to recharge my prepaid card and I had to do it from the website. I wrote a review, which has been answered saying that I am supposed to be able to perform the operation from the app. So I went back and indeed the option is NOW there. So something was wrong with the app when I tried the first time, because I am 100% sure in the start page there was only Mein tarif and no aufladen option on top.
