Overview of German Mobile Network Providers

Germany’s mobile network is powered by three main providers: Telekom, Vodafone and Telefonica (O2). These are the only companies that operate their own mobile networks. Other providers, such as Congstar, Tchibo, or 1&1, use the infrastructure of one or more of these major networks under different conditions. For example, Congstar uses Telekom’s network, while freenetmobile may offer plans on any of the three.

Telekom

Telekom offers the strongest coverage across Germany, especially in less populated areas. It’s a great choice if you live outside a major city. However, this high quality often comes with higher prices compared to other providers.

Vodafone

Vodafone provides reliable coverage and fast internet speeds, with a solid balance between performance and price. It's a popular option for both city dwellers and those in smaller towns.

Telefonica (O2)

O2 is the most budget-friendly of the three and works especially well in larger cities and urban areas. However, coverage and speeds may drop in the countryside or less populated regions.

How to Activate Your German SIM Card

No matter which SIM option you choose, activation always requires a short identification process. This is a legal requirement in Germany.

To verify your identity, you’ll need your passport and a German address. If you're buying a prepaid SIM card in a physical store, you can also use the address of your hotel or hostel for registration. The process is quick and can be completed in one of two ways:

Online via video identification from the comfort of your home

In person at a German post office using the Post-Ident service

Tips & Reminders

Since most mobile contract information is written in German, it’s easy to miss some important details. Here are a few things to keep in mind as you choose your plan:

  • Long-term contracts (like 24-month plans) no longer lock you in for another year if you forget to cancel. After the initial contract period ends, it switches to a monthly plan that you can cancel with 1 month’s notice.

  • Higher prices after 12 months are quite common, especially if the contract started with a special promotional price.

  • Some providers charge activation or setup fees when you sign up. These costs might not be obvious at first, so double-check before confirming your plan.

  • Mobile providers often run promotional campaigns with discounts or extra data. Keep an eye out for this.
