Prepaid SIM Cards in Germany: A Comprehensive 2024 Guide

No Comments


Whether you’re an expat settling down for a longer stint, a student gearing up for a semester abroad, or a tourist taking in the sights and sounds of Germany, staying connected to the internet and being able to make calls is crucial.

Unlike postpaid plans, which bill you at the end of the month based on your usage, prepaid SIM cards allow you to pay upfront for a set bundle of data, calls, and texts. This gives you control over your spending, avoids long-term contracts, and eliminates the need for a credit check—a series of benefits that make prepaid SIM cards a popular choice for international arrivals.

In this guide, we will walk you through everything you need to know about purchasing and using prepaid SIM cards in Germany.


  • Multiple locations, including airports, telecom stores, and supermarkets, offer prepaid SIM cards.
  • Activation is usually simple but may require an internet connection or a phone call.
  • Consider top providers like Vodafone, O2, and Telekom for reliable services.
  • Pricing structures vary, so understand your needs to choose an appropriate plan.
  • Topping up your SIM card can be done through various methods, such as in-store, online, and via SMS.
  • Additional features like international calling packages and data rollover can offer extra convenience.

Legal Requirements for Obtaining a SIM Card in Germany

Before picking up a prepaid SIM card and exploring Germany, there are a few legal prerequisites to be aware of. Understanding these requirements can streamline the purchasing process and help you avoid any unnecessary hiccups.

Identification Documents

In Germany, it’s mandatory to provide identification when purchasing a SIM card, whether it’s prepaid or postpaid. This rule applies to everyone, regardless of nationality. Typically, you will need to show:

  • A valid passport
  • Alternatively, a national ID card can be used if it has sufficient identification features (EU citizens usually can use their national IDs)

Some providers may also ask for proof of address, even for a prepaid SIM. This could be a utility bill or your Anmeldung (registration certificate) if you’ve already managed to register your residence in Germany.

Age Requirements

There are generally no age restrictions for purchasing a prepaid SIM card in Germany. However, note that some services, like adult content or gambling sites, may be restricted based on age, and these restrictions will be enforced by the SIM card provider.

Registration Process

Once you’ve shown your identification, you must undergo a brief registration process. This often involves filling out a form with your details. Some stores offer this service in English, but it’s always a good idea to ask beforehand if you’re not comfortable filling out forms in German.

After you have completed the registration, the store will typically take care of the activation process for you. In certain cases, especially if you’ve purchased your SIM card online or from a vending machine, you may need to complete an online or over-the-phone verification. These services are often available in English.

Where to Purchase a Prepaid SIM Card

Germany offers a variety of convenient locations to purchase a prepaid SIM card, making it fairly straightforward for newcomers to get connected quickly. Here are your primary options:


As soon as you touch down in Germany, you’ll usually find kiosks or stores in the airport selling prepaid SIM cards. This is an immediate and convenient way to connect, especially if you need to make calls or use the internet immediately. However, airport prices can sometimes be higher than what you’ll find elsewhere.

Telecom Stores

Brick-and-mortar telecom stores, often located in city centers and shopping malls, offer many options. Stores like O2, Vodafone, and Telekom have their own outlets where you can speak to a representative, compare plans, and purchase the SIM card that best suits your needs.


If you’ve researched and know exactly what you need, purchasing a SIM card online is another option. Many providers offer English-language websites and even deliver the SIM card to your residence or hotel. Remember, however, that you’ll still need to complete the identification process, either through an online verification system or by visiting a store in person.

Supermarkets and Kiosks

Many supermarkets and corner kiosks stock prepaid SIM cards for those who prefer a quick, no-fuss shopping experience. You’ll often find them near the checkout area. Aldi, Lidl, and Edeka are examples of supermarkets where you can find SIM cards from budget providers like Aldi Talk. These are often cheaper but have fewer options and amenities than specialized telecom stores.

How to Activate a Prepaid SIM Card

The activation process varies slightly depending on where you bought the SIM card and which provider you’ve chosen, but the core steps generally remain the same. Here’s how to go about it:

Step-by-Step Process

  1. Insert the SIM Card: First, remove your old SIM card from your phone and insert the new German prepaid SIM card. Depending on the make and model, you’ll usually find the SIM card slot on the side of your phone or under the battery.
  2. Turn On Your Phone: Power up your phone and wait for it to recognize the new SIM card. This usually takes a few moments. You might be prompted to enter a PIN code often provided with your SIM card package.
  3. Follow On-Screen Instructions: Some providers will send you a welcome message outlining the steps you need to follow to complete the activation. Follow these steps as instructed.
  4. Register Online or In-Store: If you haven’t already completed the identification process, you may be prompted to register online or visit a retail location to show your identification.
  5. Activate the Plan: Once the SIM card is registered, you’ll often need to activate your chosen plan or bundle. This can usually be done through the provider’s app or website or by calling a designated activation number.

Customer Service for Non-German Speakers

If you’re not comfortable with the activation process or run into any issues, most major providers offer customer service in English. You can usually find a customer service phone number on the SIM card package or on the provider’s website. Don’t hesitate to call and ask for guidance if you need it; getting your SIM card up and running is a priority for them as well.

Cost Structures

Prepaid SIM cards in Germany generally follow a few different pricing models. Here’s what to expect:


This is the most basic form of a prepaid SIM, where you pay for each call, text, and megabyte of data you use.

Ideal for those who don’t plan on using their phone frequently or for short-term visitors.

Pay-as-you-go rates can quickly become expensive if you intend to use data or make international calls.

Data Bundles

These packages offer a certain amount of data for a fixed price.

Perfect for those needing internet access for browsing, emails, and social media.

Once you exceed the data limit, you’ll either be charged per megabyte or your internet speed will be throttled.

Voice and Text Packages

These bundles offer a set number of minutes for calls and texts.

Suitable for those who expect to make frequent calls or send many text messages.

Ensure that international calls are included or come at an additional cost.

Special Offers for Students and Tourists

Some providers offer promotional packages aimed at students or tourists, which may include discounted rates or extra features like free international calls.

Ideal for students staying for a semester or tourists on an extended visit.

These plans often have a limited validity period and may require proof of status (e.g., student ID).

Combining Packages

Many providers allow you to mix and match various bundles. For example, you could combine a data package with a voice and text package.

Ideal for those who have diverse needs and want the flexibility to customize their plan.

Combining packages could sometimes yield cost savings, but make sure to compare the total cost with all-inclusive options.

How to Top-Up Your Prepaid SIM Card

Topping up prepaid SIM cards in Germany is a straightforward process, with multiple methods available to suit different preferences and needs. Here’s how you can do it:


You can visit a telecom store to buy top-up vouchers.

Simply go to the counter and ask for a top-up for your specific provider. You’ll receive a voucher with a code that you’ll need to enter into your phone.

Most telecom stores and even some kiosks and supermarkets offer this service.


Many providers allow you to top up your prepaid SIM card through their website or mobile app.

Log into your account, choose the amount you wish to top up, and pay using a credit card or PayPal.

This is an efficient way to top up your account without visiting a store, especially convenient for those comfortable navigating online payment portals.

Direct Debit

Some prepaid plans offer an automatic top-up feature via direct debit from a bank account.

Set up the direct debit authorization via your provider’s website or in-store, specifying how much and how often you wish to top up.

This is the most hands-off approach, but make sure to keep track of your usage to avoid any unwanted charges.

ATM Machines

Certain ATMs in Germany allow you to top-up your prepaid SIM card.

Insert your debit or credit card, choose the mobile top-up option, select your provider, and follow the prompts.

While not as common as other methods, this can be a quick way to recharge your account if you happen to be near a compatible ATM.


Some providers offer the option to top up by sending a text message.

Text a specific code to a designated number, and the cost of the top-up will either be added to your bill or deducted from your existing credit.

Instructions for this method are usually provided in the SIM card’s instruction manual or the provider’s website.

Coverage and Network Quality

You’ll generally find reliable networks in Germany, but there can still be variances depending on the location and the provider you choose. Here’s what you need to know:

Urban vs. Rural Areas

In cities and larger towns, most providers offer excellent coverage with high-speed data. Whether you’re using your phone for navigation or video calls, you should expect consistent and reliable service.

While coverage is generally good across Germany, some rural or remote areas may have limited service. If you plan on spending a significant amount of time outside urban centers, make sure to check the coverage maps for your chosen provider.

Data Speeds

Most top providers offer 4G LTE networks, and 5G is rapidly rolling out in many areas. If data speed is crucial for your needs, consider a provider known for high-speed data.

Be aware that if you exceed your data bundle, some providers may reduce your internet speed, known as throttling, until you top up or the next billing cycle.

Network Reliability

Network uptime is a measure of reliability. Top providers in Germany boast high uptimes, meaning you’ll rarely, if ever, experience outages.

It’s always a good idea to check customer reviews to get a sense of the network quality. Remember that experiences can be subjective and may vary based on the location.

Roaming within the EU

Germany is part of the EU’s “Roam Like at Home” scheme, which means you can use your prepaid SIM card in other EU countries without additional roaming charges. However, check your specific plan’s terms to ensure you understand any limitations.

Additional Services and Features

Apart from the standard calling, texting, and data services, many prepaid SIM cards in Germany come with a range of additional features that can enhance your mobile experience. Here’s a look at some of these add-ons:

International Calling Packages

Special bundles that offer discounted rates for international calls. It is ideal for expats or tourists who need to make frequent calls to their home countries.

These packages can often be added to your existing plan via the provider’s app or website.

Mobile Hotspot

The ability to share your mobile data with other devices.

Useful for those who carry multiple devices or travel in groups.

Using your phone as a hotspot can consume data rapidly, so monitor your usage carefully.

Data Rollover

Some providers allow you to roll unused data into the next billing period.

Ideal for users who don’t consistently use the same amount of data each month.

This feature can provide excellent value but is not standard across all providers.

Travel-Specific Plans

Plans specifically designed for short-term travelers, which may include tourist attractions discounts or bundled services like airport shuttle discounts. Targeted primarily at tourists.

These plans usually have limited validity and may not be the most cost-effective for longer stays.

Troubleshooting Tips

No matter how smooth the process of obtaining and using prepaid SIM cards in Germany may generally be, glitches can happen. Should you encounter issues, here are some practical troubleshooting tips to help you resolve them efficiently.

  • Try turning your phone off and on again to re-establish a connection with the network. You can also toggle the “Airplane Mode” on and off.
  • Manually select the network from your phone’s settings if the automatic selection isn’t working.
  • Contact customer service or visit a store for technical support.
  • Ensure that your data is turned on and that you haven’t exhausted your data bundle.
  • Check the Access Point Names (APN) settings on your phone to ensure they match what’s specified by your provider.
  • Call customer support for help or visit a store if you’re unable to resolve the issue yourself.
  • First Steps: Make sure you have sufficient credit for making calls or sending texts. Also, ensure your SIM card is properly inserted.
  • Advanced Step: Sometimes, the issue might be with the recipient’s service, so try calling or texting another number to isolate the issue.
  • Last Resort: If all else fails, contact your provider’s customer service for assistance.
  • First Steps: Double-check the top-up code for errors if you’re using a voucher and ensure you’re entering it correctly.
  • Advanced Step: If topping up online, ensure that your payment method is valid and accepted by the provider.
  • Last Resort: For persistent issues, reach out to customer service for guidance or go to a physical store.
  • First Steps: Review your usage details and plan conditions to understand the charges. Sometimes additional costs can incur from out-of-bundle rates.
  • Advanced Step: If you still don’t understand the charges, gather any supporting evidence, like screenshots or text messages related to your account activity.
  • Last Resort: Contact customer support to clarify any unexplained charges and request adjustments if applicable.
