What is the best fare?
Tariffs that can be canceled on a monthly basis offer greater flexibility compared to fixed-term contracts. On the other hand, fixed-term contracts are often more attractive when they are offered. One of the best contracts was in November 2021 and May 2022 from Freenet (formerly Mobilcom-Debitel).

If you can, you should switch to a contract that can be terminated monthly and then hit Black Week 2022.
Which network is good?
Depending on where you live in Germany, the network can be very different. In Munich, for example, O2 is excellent in the inner city area, but not usable in the subway and on the edge of the stand. Vodafone offers high coverage throughout Germany; as well as the Telekom network. If you really want to be sure whether the network is good at the desired location, you can always find a network coverage map from the respective provider. You should also ask friends and family for advice on whether they have good reception in the desired network.
What is the difference between monthly billing and every four weeks?
Some tariffs are not billed by calendar month, but every four weeks. Here the bill is issued every 28 days, which is a bit more expensive in practice.
