Best Mobile Network in Germany [2021 English Guide]

Having a German mobile phone number and plan is pretty much necessary to participate in everyday life. We take a look at the best mobile network in Germany. Additionally, we also take a look at the best mobile phone contract providers in Germany.

I have had five different mobile providers since getting my first mobile phone in 2002. So let’s take a look at what is happening in 2021.

Which is the best mobile network in Germany?

Germany has three main mobile network providers:

  1. Deutsche Telekom (T-Mobile)
  2. Vodafone
  3. O2 (Telefónica)

According to the latest in-depth study across the entire country, Telekom is the best mobile network provider in Germany for internet and phone reception in terms of availability, performance, and reliability. Vodafone comes in second and O2 as last.

Telekom has won this network test for the last nine consecutive years.

Which German mobile carrier should you choose?

You should base your decision on where you live and spend the most time in Germany. Despite the high living standards and great infrastructure in Germany, the internet and mobile reception is underdeveloped. Especially in rural areas, it is not uncommon for you to not have reception at all. Below you get an impression of the dark spots by each provider.

To find out which provider is best for your location, you can use the following network coverage checks. Simply enter your address.

Cell phone contract or Prepaid SIM

When choosing a mobile phone plan, you will also have to decide, whether you want to pay as you go and get a prepaid SIM card or whether you want a contract. Mobile phone contracts in Germany are usually binding for 24 months and the monthly fee gets pulled from your bank account automatically. 

Contracts are very popular in Germany. The advantages are getting a new phone at the same time and having the option for bigger data plans. The monthly fee of the contract increases accordingly and you get to pay your new phone in installments over the next two years. 

In this article, we will focus on the best mobile contracts.

5 Features to choose the best mobile phone contract for your needs

1. Talk time & Text messages 

Nowadays most contracts offer unlimited calls and text messages included in your contract (FLAT in German). However, you may also choose smaller packages with a minutes package.

2. Internet Data and Speed

Internet Data packages usually start with 1GB. The best mobile network in Germany for internet depends on where you live. The fastest network available is 5G, however only in certain parts of Germany. LTE (4G) is the fastest network with the biggest coverage.

🔥 Tip: Since 2017 you can use your German phone and data plan within the EU without roaming charges. This applies to private and business trips, but not for long-term stays abroad. Some providers, like Telekom, also include Switzerland in the free-roaming zone.

3. Duration of contract

Most mobile contracts run for 24 months and automatically extend for another year, should you not cancel in time. 

4. Network

You will still find the old terms of D-Netz and E-Netz used by providers. The D1-network refers to Telekom, D2 to Vodafone and E-network refers to O2.

5. Phone Number

Some providers offer you to choose your own number. In case you had a German number before, you can also opt to carry it over to your new provider. Some companies even offer a bonus for this service.

5 Best German Mobile Phone Contract Providers 

The mobile phone market in Germany is one of the toughest with countless third-party competitors, who use the lines of the three networks (Telekom, Vodafone, and O2) and often offer better prices. When comparing different providers and contracts, pay attention to possible price changes after the first 6 or 12 months. Marketing for mobile phone contracts tends to be somewhat aggressive. 

We base our selection on our own experience, in-depth research, and provider reputation. 

Disclaimer: Customer service is generally bad when it comes to mobile phone contracts and there is not one provider really excelling in it. To avoid any hassle, choose a contract once and stick with it. Don’t forget to cancel it on time (at least 3 months before the end of the contract).

To cancel your existing contract, you can access our FREE template to cancel contracts in Germany.

All listed providers also have the option to get a contract, which you can cancel each month, so you won’t be tied for 24 months. Naturally, prices for those contracts are more expensive. If you are simply looking for the cheapest and easiest option, we recommend opting for a prepaid SIM card, to really be in control and stay flexible.
