Best Mobile Network in Germany for Internet

Are you looking for a reliable mobile network provider in Germany? In general, for a network, you will have three options to choose from. On another hand, Germany has tens of different sim cards providers operating on main mobile networks. So what do you need to know about local mobile providers to choose the optimal deal?

The fact is that you will need a German sim card if you are coming to Germany. This article will help you to decide between which network and sim card providers to choose from. We give an overview of the mobile networks in Germany, mobile providers, and the best sim cards and mobile plans for any situation.

Mobile Networks in Germany

Germany is quite a monopolistic country where one major telecommunication company Telekom has the most control over mobile networks and internet connections. It is also the biggest problem of Germany because Telekom was slow in innovations and network development, hence, you can see that the internet is lacking in Germany and expensive.

Read more about why the internet is so bad in Germany in this post.

Overall, Germany has 3 main mobile networks:

  • Telekom
  • Vodafone
  • O2 (Telefónica) 

All SIM cards providers in Germany are using one of those mobile networks. O2 is the cheapest network in the country. This means that no matter which mobile contract you have, you always make calls and surf the internet on one of these three mobile networks.

The package M from O2 is one of the best mobile plans we came across so far, but you can get a SIM card for as cheap as 1,99 EUR!

All these mobile networks differ in some way and have different coverage. For example, Telekom operates the D1 network, Vodafone the D2 network, and the O2 network has an E network.

Usually, providers who use the O2 network tend to be the cheapest, and Vodafone will be slightly more expensive, the highest price you will pay for Telekom.

During the test of the German mobile network, all providers received a “very good” rate. All of them are offering 4G internet and sometimes you can even get a 5G.

WinSIM is one of the providers we recommend, it uses the O2 network.


German Telekom is probably the most common network you will come around. They are also ahead of the other operators in the expansion of the 5G network.

You can choose a contract with or without a new phone. They also have a line of prepaid sim cards. However, Telekom charges higher prices than other network providers.


Vodafone is the second largest network provider in Germany. The company has a variety of mobile plans. The company has a variety of different mobile plans: with or without contact, with or without a new phone, special prices for young people under 28 years. 

They have good and stable coverage across the country.

O2 (Telefónica)

O2 is originally a Spanish telecommunication company that has a big share of the German market. It’s the third-largest network provider and the most affordable option in Germany.

Mobile Network Coverage in Germany

Coverage isn’t equal in whole Germany. Overall, the network quality is very good in Germany. In the countryside, however, O2 is still lagging behind.

Even if the network operators receive good and very good overall ratings, this, unfortunately, does not mean that Germany keeps up with other European countries in terms of network coverage. There are still many places lacking a 4G connection.

Problems while traveling by train

You might have noticed the disappearance of mobile connection or internet while taking intercity trains in Germany. Yes, the stability of the network is lacking behind.

If you have to take an intercity train on a regular basis, Telekom was ranked the best (score of 1.53) in the connectivity in trains, on a second-place is Vodafone (1.76) and O2 (1.79) just showed slightly lower results.

However, Vodafone is the best if you need to make calls on long-distance trains, Telekom is the best for surfing the web.

What Are the Best Mobile Plans for Internet in Germany?

Mobile plans in Germany differ between prepaid plans and plans with a contract. For someone staying shorter than 1-year prepaid option is more suitable.

Since German contracts can be quite difficult to cancel. Btw, you can read in this post, how to cancel a mobile contract in Germany, if you are in this situation.

With prepaid mobile plans, you need to top up credit in order to use data or do calls. There are also few postpaid tariffs you can choose from. Where the provider will invoice you at the end of the month for the used mobile service.


Prepaid is also meant Pay-as-you-go. Most of the mobile plans you will see in Germany belong to the prepaid section. In this case, you first purchase a SIM card and after activate it by top-up the balance.

Prepaid sim cards are best suitable to people staying in Germany short term, less than a year.

The main benefit of a prepaid plan is no commitment to any contract. But once you run out of balance, you won’t able to use a sim card. Luckily, recharging credit is very easy in Germany, usually, you can do it via your mobile app or by buying credit at any kiosk or supermarket.

Benefits prepaid mobile plans offer:

  • No contract: you can quit anytime
  • You pay only when using mobile services
  • It’s cheap: Prepaid rates can be used inexpensively thanks to the minute and surf packages
  • Flexibility: you can change your plan any time, book more/faster internet, etc.

Post paid

Postpaid is the opposite of prepaid. The difference between prepaid and postpaid is when you pay. With a postpaid plan, you pay the bill at the end of the month for the used service. The amount is usually deducted from your banking account automatically. Whereas with prepaid, you have to top up a credit yourself in advance.

A post-paid plan is more suitable for people who will stay a long time in Germany because you will commit to a 12 or 24 months contract. Post-paid deals are also called “Tariffe mit Vertrag” in Germany or tariffs with a contract.

Cell phone contract

Another option to get a mobile plan in Germany is together with the cell phone. This is very common in Germany. You will basically buy a phone which is accompanied by the mobile plan.

However, the payment for the phone is stretched over 24 month period. The mobile company will deduct money automatically by the end of every month for a phone and used mobile data.

The benefit of this option is that you are getting a new phone and at the same time having access to the bigger data plans.
