This is a developed country with excellent infrastructure, so why is there a word for a dead zone in German (Funkloch)? Choosing the best mobile network operator is essential for students, expats, remote workers, and tourists.
I have done all the homework for you and made a review of the best mobile network in Germany. You will find out which network is the most reliable, whose coverage map you should use, and for whom the cheapest connection is available. In addition, I prepared answers to frequently asked questions about the coverage, operators, and network connection in Germany.
What Is the Best Mobile Network in Germany?
The short answer is Deutsche Telekom, which has been scoring the best result in the connect network test for the fifteenth consecutive year . Telekom has received the highest rating and the most points among consumers – outstanding. O2 and Vodafone ranked second with 937 points, scoring slightly below Telekom’s 975. The most popular mobile network operators in Germany are telekom.de, Vodafone.de, and O2.de .
Of course, the winner of the competition is not always the best choice for you. First of all, Telekom is expensive compared to other operators; secondly, the differences between the winners are quite small. Two other large network operators, Vodafone and O2, also received a very good rating. 1&1 Has appeared on the scene as a new player in the market that offers good value for money.
