Terrible. One can go on a loop when trying to do something, both via the app or website. Totally counterintuitive. The y say one can easily end the prepaid option by "simply" clicking a button, which is absolutely nowhere.

Hello Ari Guji, thank you for your review. At the bottom of our website, you'll find the "Vertrag kündigen" button. There you will be directed to an online form that you fill out and then submit. In the app, you will find the option to cancel the contract under Menu and then Tariff & Options.

the app does a few of the things I'd expect from it. It shows my data usage and enables me to add or change data plans. Unfortunately it often feels clumsy and laggy since it is constantly reloading pages/data that is unlikely to have changed between uses. Also: Why can't I listen to voicemails inside the app? I'd like them to be downloaded automatically as audio files. Make this happen and you'll get 5 stars.

Super dumb app it's been designed in a way you need to spend long time to find how to recharge and there is no option to view the contents in English .

Dear pradeep k, thank you for your review. We are sorry that you had difficulties with recharging via the app, but now it works? Unfortunately, our app is currently only available in German. We have no information about other plans.
