Ratings and reviews

Fixing what isn't broken. The app is only available in German (you could use your browser's translate feature on the site). I thought I'd at least benefit from the data amount-tracking widget placed on my home screen, but it doesn't automatically update and requires you to enter the app and pull down to refresh..

Here is my experience with Congstar: I signed a contract with a dealer and was doubly deceived regarding the GB amount and the cancellation options. After installing the app, I received a fraudulent SMS asking me to enter my bank details. Since the message was in yellow, I thought it was related to Congstar, but it was a scam. Customer support didn't want to help and seems to support deceitful dealers. Stick with a reputable company, as Congstar is only after quick money.

Good value and customer service. perfect for a summer garden as you can put it on hold. The 200GB limit has started to become a problem tho since we have to keep buying more data so it's stressful to buy it before the data runs out. this month we have 350 which is a surprise - not sure if that's a one off. Recommended for convenience and great customer service on chat.
