The worst mobile coverage of Germany. They are giving the best options, the most GB of internet which you can not use. I made this mistake and I still have like 15 more months. After it is over I will burn the sim card and the contract in front of an O2 store. I live in Bodensee area and can you believe that the Swiss operators are giving WAY BETTER signal from 6-7 km away.



The internet speed: In city center it might compete with a 56k router, maybe!!!



When you travel between the cities other operators are giving at least signal but O2 is giving nothing. If your car is broken you can not call anyone.



Sooo my advice is, instead of using O2 you better communicate with smoke like Indians. Believe me it will be way faster and efficient.
