Cong star is very cool and accommodating and the customer service is excellent.

Even as someone with only a toddler's understanding of German, I find this app easy enough to use. I recently made some changes to my family's phone plan in the app, it went smoothly without issue.

Everything is fine. It doesn't have English in the settings :/ Icons on the navigation bottom bar is too thin, it could look much better. Anyway, thx for the nice service 🙂

I am a very big fan of costars offers, the app and the support chat. The app is easy to understand and navigate and in the support chat they always replied to me very fast, very polite and very helpful!

The app is hideous, it has so many "security" measures, I have to write my contact number by hand somewhere to just be able to do anything, because they weren't smart enough to make your app, when you are logged in, and you want to end a contract, it doesn't recognize the contact you want to end automatically! The Internet service is also bad, it was a problem to get someone to come fix it. This is one of the reasons I'm leaving Germany, is impossible to have a service tha has anything normal

You can only log in of you have access to the phone number in the contract. The website does not provide a regular login anymore or requires 2FA to the same name which renders the whole contract management useless.

I've been with Cong star for well over a decade, and I've always believed in the saying, "If it's not broken, don't fix it". What was wrong with the website? Nothing was wrong for the user. Now, another ridiculous app. Yet another app to deal with on multiple platforms. More work, more data for less result. As a reply to your reply below: feels AI generated... what future are you referring to? I'm paying now.
