- Germany has four mobile network operators: Telekom, Vodafone, O2 and 1&1. Every other brand – congstar, fraenk, SIMon mobile, Aldi Talk, Lidl Connect, Edeka smart and the rest – sells access to one of the first three networks.
- Telekom has the best-rated network and the highest prices, Vodafone combines good coverage with mid-range prices, and O2 is the budget choice with strong urban coverage. In the connect network test 01/2026 all three scored at least “very good”.
- Prepaid SIM cards need no bank account, no credit check and no minimum term. Mobile contracts run for up to 24 months, are cheaper per gigabyte and usually involve a SCHUFA check and a SEPA direct debit.
- Since 2017 every German SIM card must be activated with an ID check before it works – online by video, at a post office, with the eID function of your residence permit, or in a shop. A temporary address is enough; which route accepts your passport is explained in our SIM verification guide.

German mobile operators
Germany has four mobile network operators: Telekom, Vodafone, O2 and 1&1. Telekom, Vodafone and O2 run the three nationwide networks that every SIM card in Germany ends up on – either directly or through one of the many discount brands. 1&1 is the newest network operator and is still building out its own antenna network, so its coverage depends on where you live.
- Telekom has the best-rated coverage but charges higher monthly fees.
- Vodafone offers good coverage at more affordable rates.
- O2 delivers weaker rural coverage than Telekom and Vodafone but compensates with cheaper monthly fees and strong urban availability.
- 1&1 sells competitive digital tariffs on its own, still expanding network – check the coverage at your address before you sign.
The independent network tests agree with that order without disqualifying anyone: in the connect mobile and 5G network test (issue 01/2026), Telekom scored “outstanding” with 975 points, Vodafone and Telefónica/O2 each scored “very good” with 937 points. CHIP (November 2025) and ComputerBILD (issue 23/2025) also ranked Telekom first. The Federal Network Agency publishes the operators’ own coverage data on an interactive map (Mobilfunk-Monitoring in the Gigabit-Grundbuch) – it shows outdoor coverage in 100-metre squares, which is the map to check for a specific address.
Mobile network comparison in Germany
| Network | Best for | Coverage profile | Own brands and discount brands on this network | Expat note |
|---|---|---|---|---|
| Telekom | Best overall coverage and rural reliability | Test winner (connect 01/2026, CHIP 11/2025, ComputerBILD 23/2025) | MagentaMobil, MagentaMobil Prepaid; congstar, fraenk, Edeka smart | Best choice if you travel often, live rurally, or need maximum reliability. Telekom’s EU roaming also covers Switzerland and the UK. |
| Vodafone | Good balance of coverage, speed, and price | “Very good” (connect 01/2026, 937 points) | Vodafone Mobil, CallYa; SIMon mobile, Lidl Connect | Often a practical compromise between Telekom quality and O2 pricing; UK included in EU roaming, Switzerland not. |
| O2 (Telefónica) | Budget users and city residents | “Very good” (connect 01/2026, 937 points); weaker in some rural regions | O2 Mobile, O2 Prepaid; Blau, Aldi Talk | Often the best value if you live in a major city; Switzerland only via a paid day pass. |
| 1&1 | Digital contracts and users who want Germany’s newest network option | Own network still expanding | 1&1 | Check the coverage at your address; outside its own network areas 1&1 relies on a partner network. |

Telekom
Telekom, known internationally as T-Mobile, is Europe’s largest telecommunications company and the go-to German mobile provider for those seeking the best coverage. The former D1 network is now simply called the Telekom network; its quality comes at a cost, with plans being pricier than those of its competitors.
Telekom won the connect network test 01/2026 with the only “outstanding” rating in the field and also topped the CHIP and ComputerBILD tests of late 2025. The excellent coverage and reliability make Telekom a top choice for those who prioritise quality and don’t mind higher prices – and Telekom is the only network operator whose EU roaming also includes Switzerland and the United Kingdom.
Vodafone
Vodafone is one of Germany’s major mobile network operators. It runs the former D2 network and delivers fast mobile internet speeds and good area coverage. Its postpaid tariffs are called Vodafone Mobil (the GigaMobil name is still used for older plans), its prepaid brand is CallYa.
Vodafone’s EU roaming includes the United Kingdom; Switzerland is not part of the roaming zone and needs a separate travel package.
O2
O2, operated by Telefónica Germany, is one of Germany’s major mobile network operators. It offers lower tariffs and high data volumes, making it an excellent choice for those living in larger cities. O2’s rural network coverage is less comprehensive than Telekom’s or Vodafone’s, although the network scored “very good” in the connect test 01/2026 like Vodafone’s.
O2 sells its own O2 Mobile contracts and O2 Prepaid cards and is the network behind Aldi Talk and Blau. For Switzerland, all O2 Mobile tariffs include “Roaming Plus”: a day pass that activates automatically at the border and is charged per day of use.
1&1
1&1 is Germany’s fourth mobile network operator. It is building its own network and, where that network is not yet available, uses a partner network for coverage. Because the 1&1 network is still smaller than Telekom, Vodafone or O2, check the coverage at your address carefully, especially if you live outside a major city or frequently travel through rural areas.
For expats, 1&1 can be interesting because it offers competitive digital tariffs with and without a minimum term. All four networks may offer discounts for combining internet, landline, and mobile services in your contract. It’s worth inquiring about these offers when signing up.
Mobile Virtual Network Operators (MVNOs)
In addition to the four physical mobile operators, Germany is also home to many Mobile Virtual Network Operators (MVNOs) and second brands. These providers use the infrastructure of the network operators, often delivering the same coverage at cheaper prices. What differs is the maximum speed, the extras and the service.
The most relevant brands for newcomers are:
- on the Telekom network: congstar (Telekom’s own discount brand, prepaid and contract), fraenk (Telekom’s app-only brand: a monthly cancellable postpaid plan paid by PayPal, Apple Pay, Google Pay or SEPA, with EU roaming that includes Switzerland and the UK) and Edeka smart (supermarket prepaid).
- on the Vodafone network: SIMon mobile (Vodafone’s monthly cancellable app brand with 5G included) and Lidl Connect (supermarket prepaid with 5G in all Smart and Data tariffs).
- on the O2 network: Aldi Talk (supermarket prepaid, starter sets in every Aldi store) and Blau.
Network and data selector for expats
Use this quick selector before choosing a German SIM card:
| Your situation | Best choice | Why |
|---|---|---|
| I am staying short-term or just arrived | Prepaid SIM | No long contract, easier activation, and less risk if you move again. |
| I live in a major city and want low prices | O2 or an O2-based discounter | Urban coverage is often strong and data allowances are usually generous. |
| I need the best rural coverage | Telekom or a Telekom-based brand | Telekom usually performs best outside major cities. |
| I want a budget prepaid plan | Aldi Talk, Lidl Connect or Edeka smart | Supermarket prepaid with simple 4-week packages and top-up vouchers at the checkout. |
| I travel to Switzerland or the UK a lot | Telekom or fraenk | Both include Switzerland and the UK in EU roaming; most others do not include Switzerland. |
| I want a phone included | Mobile contract | Contracts can bundle a smartphone into the monthly price, but usually require a credit check. |
| I have no SCHUFA history yet | Prepaid SIM or a monthly cancellable app plan | Prepaid needs no credit check; monthly plans such as fraenk or SIMon mobile carry less risk for the provider than a 24-month contract. |
| Editorial assessment based on the providers’ tariff pages and our own product database, as of September 2026. | ||
EU roaming, Switzerland and the UK
As part of the EU, Germany applies the “roam like at home” rules: you use your German SIM in the other EU countries, in Iceland, Liechtenstein and Norway, and since 2026 also in Moldova and Ukraine, at domestic prices. Providers may apply a fair-use check: if over four months you spend more days abroad than in Germany and use the SIM more abroad than at home, they may ask you to explain and charge regulated surcharges. Calls from Germany to other EU countries are not roaming – for non-flat tariffs the EU caps them at 19 cents per minute and 6 cents per SMS plus VAT.
Switzerland and the United Kingdom are not covered by the EU rules. Whether they are included depends entirely on the provider:
| Provider | United Kingdom | Switzerland |
|---|---|---|
| Telekom (MagentaMobil) | Included | Included |
| fraenk | Included | Included |
| Vodafone (Vodafone Mobil, CallYa) | Included (“remains part of the EU roaming zone”) | Not included – EasyTravel packages |
| SIMon mobile | Included (incl. Gibraltar) | Not included – Travel-Data options |
| O2 (O2 Mobile) | Check the tariff | Not included – Roaming Plus day pass, activates automatically |
| congstar | Check the tariff | Not included (“not part of the EU or country group 1”) |
| Aldi Talk | Billed like the EU zone until 31 December 2026 (extension reserved) | Not included – Europe options |
| Sources: the providers’ roaming pages and price footnotes, retrieved on 24 September 2026. Prepaid cards of Telekom follow the EU rules; check the prepaid price list for Switzerland and the UK. | ||
Prepaid SIM or mobile contract?
The choice between a prepaid SIM card and a mobile phone contract largely depends on your needs and the duration of your stay in Germany. Prepaid SIM cards allow more freedom and are typically pricier per gigabyte. They are suitable if you don’t use your phone much, only stay in Germany briefly, or arrive without a German bank account.
On the other hand, German phone contracts offer cheaper rates and are more popular among those intending to stay for a while.
Prepaid SIM
Prepaid SIM cards provide a convenient and fast way to obtain a functioning German phone number, all without the need for a contract. They are great for making calls, sending SMS messages, and using mobile data. Telekom, Vodafone, O2, and many discount brands offer prepaid SIM cards, and you can top up your mobile credit online, through your mobile operator’s app, or by buying top-up cards from retailers.
Prepaid tariffs generally cost slightly more than phone contracts but offer the flexibility of stopping whenever you want, making them a suitable option for those unsure of how long they will stay in Germany. Our guide to prepaid SIM cards in Germany compares the packages in detail.
Mobile contract
A mobile phone contract is a great option if you plan to stay in Germany for a while or use your phone a lot. Mobile phone contracts typically offer:
- A minimum term of up to 24 months – or a monthly cancellable version, which every provider must offer under the Telecommunications Act
- Cheaper rates per gigabyte
- A small, one-off activation fee at the start of the contract
- The option to add the latest smartphone
They are ideal for expats planning to stay for a few years or for those who want to upgrade their phones.
The device is paid off in monthly instalments, and at the end of the contract, the phone is yours to keep. Ordering extra services or devices later may not extend your original term unless you expressly agree (§ 66 TKG).
Mobile contracts in Germany usually involve a credit check with SCHUFA, Germany’s main credit bureau. This can be difficult for new arrivals because you may not yet have a German credit history, a long-term address, or a stable payment record in Germany. If your contract application is rejected, it does not always mean you have bad credit. It may simply mean the provider cannot assess your profile yet.
A prepaid SIM card is usually the easiest first option if you recently moved to Germany, live in temporary accommodation, or do not yet have a German bank account. Once you have Anmeldung, an IBAN, and some payment history, contract approval usually becomes easier. What SCHUFA actually checks, and how you get your free copy of your data, is explained in our guide to SCHUFA and telecom contracts.
Best prepaid SIM cards in Germany
The best prepaid SIM cards in Germany come from the network operators themselves: Telekom MagentaMobil Prepaid, Vodafone CallYa and O2 Prepaid. Each family box below shows the current packages, prices and data volumes.
Telekom MagentaMobil Prepaid

The Allnet Flat tariffs are available as eSIM and can be cancelled through congstar’s online form, the app or by post.
1&1 Mobile
1&1 offers mobile contracts on Germany’s fourth network. Because the 1&1 network is still expanding, customers use a partner network where 1&1 does not yet have its own coverage. This makes 1&1 an interesting option for price-conscious users, but coverage should always be checked carefully for your postcode.
1&1 can be a good fit if you want a competitive contract and do not need Telekom-level rural coverage.
Best unlimited internet SIM cards in Germany
Unlimited data is available both on contract and prepaid: Telekom sells MagentaMobil XL (24 months or Flex) and MagentaMobil Prepaid Max, Vodafone sells Vodafone Mobil XL and CallYa Black, O2 sells its unlimited O2 Mobile plans with different speed caps.
Telekom MagentaMobil XL
Telekom offers contract and prepaid tariffs with unlimited mobile internet in Germany:
€84.95 monthly
+ €39.95 one-time
€84.95 monthly
+ €39.95 one-time
€108.58 monthly
Advertising notice: provider links in this overview are affiliate links — we receive a commission from the provider for sign-ups made through them.
These options provide access to the 4G and 5G networks with the highest speeds Telekom sells to consumers. Telekom also lets a family order additional SIM cards on the same plan at a reduced price.
Vodafone Mobil XL and CallYa Black
Vodafone offers one contract plan and one prepaid package with unlimited mobile internet in Germany: Vodafone Mobil XL on contract and CallYa Black on prepaid, billed every 4 weeks. Both run on Vodafone’s 5G network; the current prices are in the family boxes above.
O2 Mobile Unlimited
O2’s unlimited plans differ in the maximum speed rather than in the data volume – the entry plan is capped at a speed that is fine for messaging and streaming, the top plan runs at full network speed. All of them are shown in the O2 Mobile family box above.
Cheapest SIM cards in Germany
If you’re on a tight budget and looking for a cheap SIM card in Germany, the supermarket brands are the usual answer – Aldi Talk, Lidl Connect and Edeka smart – along with the network operators’ own discount brands. They are also the most popular options among students.
Lidl Connect
Lidl Connect, offered by the German supermarket chain Lidl, is a prepaid SIM card on the Vodafone network. All Smart and Data tariffs include 5G, the packages run for 4 weeks, and there are annual tariffs for people who stay longer and want to pay once.
Aldi Talk
Aldi Talk, the prepaid brand sold in every Aldi store, runs on the O2 network, which has excellent reception in many cities but can be weaker in rural areas. Its 4-week packages renew automatically as long as there is credit on the card; top-up vouchers are sold at the checkout. Aldi Talk also offers annual packages and “Home & Go” router options for home internet.
Edeka smart
Edeka smart is the supermarket brand on the Telekom network. It is managed entirely through its app, offers eSIM, and identifies new customers through the Nect app or POSTIDENT.
Free SIM cards in Germany
Both Vodafone and O2 offer a prepaid SIM card without a basic fee: Vodafone CallYa Classic and the O2 Prepaid Freikarte. You only pay for what you use.
Vodafone CallYa Classic
Vodafone offers the CallYa Classic prepaid SIM card without a package price, charging per megabyte, minute and SMS instead. This German pay-as-you-go SIM can be a cost-effective choice for those who don’t use their phones frequently – and it is the quickest way to get a German number for verification codes.
O2 Prepaid Freikarte
O2’s free prepaid card works the same way: no package, usage billed per unit, and you can switch to one of the O2 Prepaid packages later. Like Vodafone’s card, it is ideal for infrequent phone users.
How to get a German SIM card?
You can purchase a German SIM card either online or in physical stores such as:
- cell phone stores and the operators’ shops
- grocery stores and supermarkets
- petrol stations and kiosks
Buy a SIM card online
Follow the link of one of the mentioned providers to buy a SIM card online. You will have to enter your German address, and the physical card will generally arrive in 2–3 business days via mail. Vodafone CallYa, O2 Prepaid, Aldi Talk, Edeka smart, fraenk and SIMon mobile can also deliver an eSIM, which skips the postal delivery.
After purchasing, you can top up your mobile credit through the mobile operator’s app or by purchasing top-up cards from retailers.
Activate your German prepaid SIM card
To activate your German prepaid SIM card, the provider must verify your identity before switching the card on – § 172 of the Telecommunications Act has required this since 1 July 2017. The law accepts an ID card, a passport, any other official photo ID that is valid in Germany, a residence permit, and the arrival certificate or residence authorisation issued to asylum seekers. A German contact address is part of the registration; a temporary address is enough.
For expats and tourists, activation can be harder than buying the SIM card. Some video identification partners only accept the documents on their list, and a name that does not match the registration data exactly leads to a rejection. If your passport is rejected online, your webcam quality is too low, or your temporary address is not accepted, try a different activation route instead of buying another SIM immediately.
- Activate in a physical shop: Telekom, Vodafone, O2 and their retail partners check your ID directly; Aldi Talk lists more than 10,000 partner shops for this.
- Choose PostIdent when available: congstar, SIMon mobile, Edeka smart and Vodafone let you identify at a Deutsche Post branch, which is easier than webcam verification with an unusual passport.
- Use the eID function: the electronic residence permit (eAT) of non-EU residents and the eID card for EU citizens carry an online ID function that congstar and Vodafone accept.
- Use passport-friendly providers: if one provider’s identification partner rejects your passport, another prepaid provider with a different partner may still accept it.
German prepaid SIM cards must be identified before use. For many expats, the biggest hurdle is not buying the SIM card, but completing the activation. Video identification can fail if the identification partner does not support your passport type, if the document is hard to read on camera, or if your entered data does not match the document exactly.
If video ID fails, try the PostIdent option at a post office, use a provider with better support for international passports, or activate the SIM in a physical shop. Bring your passport, your German contact address and, if available, your residence permit. Step by step, with the accepted documents per provider: SIM card verification in Germany.
How to get a German mobile contract?
You have the option to do it online or by visiting a local telecom’s outlet. Both methods are available for your convenience. Just be mindful that shop assistants may not speak English.
To sign up, you’ll need to provide proof of identity, an address in Germany, and a bank account with a SEPA IBAN for direct debit payments; fraenk also takes PayPal, Apple Pay and Google Pay.
A mobile contract will usually trigger a SCHUFA check. If you are new to Germany and have no German credit history, a prepaid SIM or a monthly cancellable app plan is the easier first step. Before you sign anything, the provider must hand you a contract summary with the term, the prices and the cancellation rules.
How to cancel a German mobile contract?
Cancelling a German mobile phone contract follows the rules of the Telecommunications Act: the initial term ends after 24 months at the latest, and once the contract has renewed, you can cancel at any time with one month’s notice (§ 56 TKG). Extraordinary cancellation before the end of the term needs a legal reason – for example, a unilateral change of the contract by the provider, a persistent shortfall in the promised speed, or a move to a place the provider cannot serve.
Providers that sell contracts online must offer a cancellation button on their website (§ 312k BGB) and confirm your cancellation immediately. Cancellations are also accepted through the customer portal, the app or in writing; O2, for example, asks prepaid customers to cancel by signed letter.
If you want to keep your number, you do not have to wait for the end of the contract: § 59 TKG lets you port a mobile number at any time, free of charge – the old contract simply continues until it ends, and the old provider gives you a new number for it. After the end of a contract, you can still request the transfer for at least one month; many providers allow 90 days.
Checklist before you sign up
Ten checks before you buy a German SIM card, an eSIM or a mobile contract:
- Activation method: VideoIdent, an ident app, PostIdent or a shop – and whether your passport is accepted for it.
- Cancellation rules: minimum term, renewal and the monthly cancellation right after the first term.
- Contract language: save a copy of the German terms before you sign.
- Coverage: the network at home, at work, at university and on your commute.
- Documents: passport or ID, a German address and a payment method.
- Payment method: German IBAN, SEPA direct debit, credit card or PayPal – not every provider takes every one.
- Price after the promotion: the regular monthly price after the first 6, 12 or 24 months.
- Roaming: EU roaming, Switzerland and the UK, international calls and the fair-use limit.
- Support language: whether app and customer service work in English.
- Your number: you can take it with you when you switch provider, and still up to one month after the contract has ended (§ 59 TKG).
Final thoughts
Choosing the best SIM card or mobile contract in Germany largely depends on your needs and circumstances. While Telekom offers the best-rated and most extensive mobile network, its high costs might not be suitable for everyone. Vodafone offers fast data speeds and overall strong quality at a better price, and O2 is the value choice in the cities.
The discount brands and app-based plans have made the market friendlier for newcomers: fraenk and SIMon mobile give you a Telekom or Vodafone SIM without a 24-month commitment, and Aldi Talk, Lidl Connect and Edeka smart give you a German phone number for the price of a starter set – without a bank account and without a SCHUFA check.
Just make sure that if you opt for a contract, you know the length of the minimum term, and that your phone is unlocked before you insert a German SIM or install a German eSIM.
Frequently Asked Questions
Yes. Anyone can buy a prepaid SIM card in Germany – online, in the operators’ shops, in supermarkets or at petrol stations. Before the card works, the provider must verify your identity; the law accepts passports, national ID cards and residence permits, and a temporary German contact address is enough. Make sure your phone is unlocked and supports the German frequency bands.
Telekom. In the connect network test 01/2026 Telekom was the only network rated “outstanding” (975 points), while Vodafone and O2 both scored “very good” (937 points); CHIP and ComputerBILD ranked Telekom first as well. Discount brands such as congstar, fraenk and Edeka smart use the Telekom network at lower prices.
A prepaid SIM card is paid in advance, has no minimum term, needs no bank account and no credit check, and costs a little more per gigabyte. A mobile contract runs for up to 24 months (or is monthly cancellable), is billed by SEPA direct debit, usually involves a SCHUFA check and can include a smartphone. App-based plans such as fraenk and SIMon mobile sit in between: postpaid, but monthly cancellable.
Yes. Vodafone CallYa Classic and the O2 Prepaid Freikarte have no basic fee – you pay per megabyte, minute and SMS. Both still require the ID activation, and both can be upgraded to a package later.
It depends on the provider, because neither country is covered by the EU roaming rules. Telekom and fraenk include both Switzerland and the UK, Vodafone and SIMon mobile include the UK but not Switzerland, O2 charges a day pass in Switzerland, and Aldi Talk bills the UK like the EU zone until the end of 2026. In the EU, Iceland, Liechtenstein, Norway, Moldova and Ukraine every German SIM works at domestic prices.
After the initial term of at most 24 months the contract renews, and you can cancel at any time with one month’s notice (§ 56 TKG). Providers that sell online must offer a cancellation button on their website (§ 312k BGB). You can take your number to a new provider at any time free of charge – the old contract simply runs until it ends.
