This information is critical for comparing German mobile network providers and identifying the best SIM card for internet use in Germany. Overall, taking into account both mobile internet and phone reception, Telefónica (O₂) ranks third, followed by Vodafone and Telefónica (O₂).

Deutsche Telekom continues to lead in mobile internet reception according to Connect Magazine’s yearly tests. But other carriers like Telefónica and Vodafone are coming up quickly. To sum it up, the best German SIM card for unlimited internet usage depends on where you reside and how much time you spend on your phone each day.

German SIM card offers an Unlimited Data Plan

O₂, Telekom, and Vodafone provide unrestricted amounts of data packages. There are a number of unlimited internet sim cards in Germany that also include free phone and SMS tariffs. As we said in this guide, we will tell you all about unlimited internet packages in Germany.

When you sign up for the phone contract, you mostly get two types of options.

Postpaid (Contract based): These contracts usually have a validity of 2 years. They are usually cheaper than the prepaid packages but here you are bounded for 2 years with the same company. Usually in Germany, you can’t end your contract before the end of your contract. Unless the provider mentions that you can cancel it with a one or three months notice period.

Prepaid (Pay as you go): The name of this package says it all. You top up your sim card to benefit from unlimited internet, call and SMS packages. If you don’t want to use your Simcard for a few months then you just simply stop topping up your sim card. Keep that in mind, some providers deactivates your Simcard if you don’t use it for a longer period of time.


O₂ is a British company and their headquarter is based in Slough, English. It is a joint venture of Liberty Global and Telefönica.

They offer all kind of plans, but here we only consider their unlimited data plans which starts at just 29.99€ per month, making it the most affordable option in Germany.

With O₂ , you do not get one unlimited plan but they offer a variety of unlimited data plans to choose from. Each package has a different upload and download speed and based on this the monthly tariff also changes.

For browsing websites, using WhatsApp, and watching YouTube videos in standard definition, this is plenty” (SD).

Free Unlimited Smart (O₂)

The O₂ Free Unlimited Smart plan boosts download and upload speeds to 10 Mbps and 5 Mbps, respectively. That’s all you need to play games, stream in HD, and make video calls. On a 24-month plan, it costs 39.99 euros each month.

Up to 500 Mbps download and 50 Mbps upload speeds are available with the Max tariff on the O₂ network. On a two-year contract, it costs 59.99 euros per month.

There is a Flex option for each of the three programmers, which removes the 24-month commitment. As an alternative, you can choose to cancel each month. It costs an additional 5 euros for every plan to get this option.

Edeka, on the other hand, is the only prepaid SIM card reseller to provide an unlimited package. They directly compete with Deutsche Telekom because it offers a similar plan for 5 euros less than Telekom, which makes it a reseller of the Telekom network.

That leaves you with a balance of 95,50 euros after four weeks.

You will be required to provide proof of your identity, either through video call or by visiting your local post office, as is the case with all German mobile phone contracts.


A 24-month contract for 79.99 euros per month gets you an unlimited data package from Vodafone.

How to Get Free Internet Access in Germany?

Free WIFI connections are available in Germany in exchange for your email address and other personal information. These hotspots can be found in airports, cafés, train stations, and all across the city.

WIFI or WLAN pillars in German are the most common markings on them. Instead, of pacing the streets in search of them, try using a service called WIFI Map. Using this software, you can identify and connect to the nearest hotspots more quickly.

Maps for offline use can also be downloaded from the app and used even if you don’t have an internet connection. However, we strongly recommend that you use a VPN that you can control if you frequently use open WIFI networks. It includes a VPN.

Can An Unlimited SIM Card Take the Place of Your Home Internet?

Because your phone has an unlimited data plan, you may think that your apartment doesn’t need a separate internet connection. If your home’s mobile service enables it, you may easily create a wireless hotspot for your laptop or TV using your phone.

According to the terms and conditions of some service providers, however, full-time home use is not permitted at all. Every month, you’ll have to get out of the house to avoid having your contract or connection terminated if you use too much data from the same location or at the same time. Using your SIM card at home with an LTE or WIFI router is also not uncommon.

Choosing the right internet service provider for your house is a complicated process, so we’ve put up an in-depth guide to help you make the right decision.


Germany’s telecommunications companies have improved their services in recent years, making it easier to get access to unlimited mobile internet. Even if an unlimited internet SIM card in Germany costs about 100 euros per month, it would have cost 200 euros just a few years ago. When it comes to price-to-value, we believe O₂ offers the greatest deal with their O₂ Free Unlimited Smart, which starts at 39,99 euros per month and provides you with a 5G unlimited connection.
