Unlimited Internet SIM Card Germany: All 13 Mobile Data Plans Compared

Prepaid vs. Postpaid Plans

Originally, unlimited data plans were exclusively available with binding postpaid contracts. However, the situation has changed. Meanwhile, prepaid unlimited SIM cards have become available for purchase online or in stores across Germany. This flexibility of pay-as-you-go service without needing a long-term contract particularly appeals to travelers or expats in Germany who want to avoid committing in the long run. Prepaid SIM cards can be recharged based on your actual data needs. They are also easier to acquire, as an identity check is the only formal requirement.

Conversely, postpaid plans typically involve a contract with the provider. They offer lower rates and discounted mobile devices in exchange for a commitment to a set term. However, they also require a more substantial initial commitment and have stricter requirements. You will need a German residence and a local bank account, and you must pass the provider’s credit check.

LTE / 4G vs. 5G Speed of Network in Germany

The evolution from LTE / 4G to 5G networks in Germany marks a significant leap in mobile internet capabilities. While 4G has provided reliable high-speed internet for years, 5G takes it to another level with dramatically faster speeds, reduced latency, and higher capacity. For those demanding data-heavy services like streaming 4K videos and engaging in online multiplayer games, choosing a data plan that offers 5G connectivity is worthwhile. Especially cheaper unlimited data plans have connection speed caps.

Furthermore, you must consider coverage and compatibility. While 5G coverage rapidly expands across Germany, some areas are still under development. If you live outside of Germany’s large agglomerations, check the local network coverage of your chosen provider. If you have an older mobile device, please also ensure it is 5G-compatible to take advantage of your plan’s benefits.

Best Mobile Network among Internet Providers

Germany has three major network providers: Telekom, Vodafone, and O2. Furthermore, 1&1 has just started building a fourth network. Service quality and speed can vary, especially in rural areas. Customer reviews and independent network performance assessments can provide valuable insights into which provider offers the most reliable service for unlimited data needs.

Considering the broad coverage maps these providers offer and their performance in specific locations is essential. You can figure out the available speed in our dedicated article on German mobile networks or on the provider’s maps:

Finding the Best SIM Card for Unlimited Internet

You can buy your unlimited SIM card either in-store or online. In-store, you enjoy personalized service and on-the-spot activation, which can benefit those unfamiliar with the local mobile internet landscape. Additionally, you can walk out with your new SIM card activated and ready to use.

However, the experience of getting a SIM card online has completely changed and often offers more advantages. Some internet providers no longer sell their SIM cards in physical stores and only provide them digitally. Furthermore, online deals are usually more beneficial, offering discounts, sign-up bonuses, or waiving setup fees. If you have a modern device compatible with eSIM, you no longer have to wait for the card to be delivered. After ordering your eSIM online, you immediately receive the setup information and are online within minutes.
