Home Internet in Germany: How to Choose a Provider and Contract

When choosing home internet in Germany, people don’t just go by the price and speed advertised. It’s more important to check the specific address, the type of connection available, the minimum contract term, the cost of the router, the terms for moving to a new location, and the actual total price after any promotions. One building might offer DSL, cable, fiber-optic, or a mobile router, while the options in the neighboring building may already be different.

What to Check Before Choosing a Plan

Before signing a contract, gather basic information about your residence and compare offers based on the same terms:

exact address: ZIP code, city, street, house number, floor, and apartment number;
What technologies are available at the address: DSL, cable, fiber-optic, or mobile internet;
the advertised download and upload speeds, as well as the minimum or typically available speeds listed in the provider’s documentation;
contract term, automatic renewal, and cancellation period;
the cost of installation, delivery, and renting or purchasing a router;
the final price after the introductory discount expires;
Is a technician’s visit required, and who sets up the equipment?
Is it possible to transfer the contract when moving?

Don’t base your decision solely on a plan that worked for a friend. In Germany, internet quality and availability often depend on the specific line, cable network, the building’s infrastructure upgrades, and network congestion.

Main Types of Internet Connections

DSL

DSL works via a telephone line. It is one of the most common options for apartments, especially where there is no cable network or fiber-optic infrastructure. Speed depends on the distance to the network node and the condition of the line, so checking the address is essential.

Cable

Cable internet runs through the television cable network. It often offers high download speeds, but in some buildings, speeds may drop during peak hours because the network is shared among users in the same segment.

Fiber Optic

Fiber-optic internet usually provides the most stable and fastest connections. However, availability depends on whether fiber has been installed in the building or apartment. If the building is only in the planning stages for installation, the wait time may be significantly longer than for a standard DSL or cable connection.

Mobile Router and FMS

Home internet via a mobile network is suitable as a temporary solution, for short-term housing, or for addresses without a standard wired connection. Before making a choice, it’s important to check coverage, data limits, fair use policies, and signal quality inside the apartment.

What documents and information are usually required

When signing up, the provider usually requests personal information and the connection address. Depending on the company, you may need to provide:

name, date of birth, and contact information;
the connection address and the mailing address, if different;
a valid form of identification;
IBAN for payment deductions;
Desired start date for the contract;
Information from your previous provider, if you need to port your number or switch providers.

A German bank account usually simplifies the sign-up process, but the terms depend on the specific provider. If you’re using an account from another EU country, it’s best to check in advance whether the provider you’ve chosen accepts it.

Router: Rent or Buy

To set up a connection, you’ll need a compatible router or modem-router. Providers often offer equipment for rent, sometimes include a basic model in the plan, or allow you to use your own device.

Renting is convenient because the provider is responsible for compatibility and replacing equipment according to its own policies. Buying may be more cost-effective for long-term use, but the device must support a specific connection type: DSL, cable, fiber-optic, or mobile network. For cable and fiber-optic connections, it’s especially important to check compatibility in advance.

How long does it take to get connected?

Timelines depend on the technology, the availability of a free line, equipment delivery, and whether a technician’s visit is required. A mobile router can start working shortly after the SIM card is activated. For cable and DSL, you often have to wait for the router and the activation date, and sometimes a technician’s visit is scheduled. Fiber-optic service can be connected quickly if the line is already installed in the apartment, or it can take a long time if infrastructure construction or upgrades are required.

The practical conclusion is simple: order internet service immediately after signing the lease agreement, provided you already know your move-in date and that a technician will have access to the apartment.

How to Compare Offers Without Falling Into Traps

The advertised price often applies only to the first few months. For a fair comparison, calculate the average cost over the entire minimum contract term and consider one-time fees separately.

A handy comparison chart:

What to Compare	Why It’s Important
Price after the promotion	Payments may increase after the promotional period
Minimum Contract Term	The minimum contract term affects your flexibility when moving
Notice Period	The notice period is important if you want to switch providers
Router	Rental fees increase the monthly cost
Anschlussgebühr	A one-time fee can make a cheap plan less cost-effective
Available Technologies	DSL, cable, and fiber-optic differ in stability and speed
Terms for moving	Not every contract can simply be canceled at will

Consultants and Selection Services

For newcomers to Germany, services and consultants that check availability by address, explain contract terms, and help with the application process are helpful. For example, ComComfort states that it provides consulting on telecommunications contracts, internet, mobile communications, and related services in Germany.

When working with any provider, be sure to clarify the following:

Who is your actual provider under the contract;
Does the broker receive a commission from the provider?
Which services are free, and for which might there be a separate charge;
Who provides support if problems arise after setup;
In which languages is customer support available;
Where can you find the company’s official contact information?

Do not sign a contract until you have seen the total price, contract term, speed, equipment, cancellation terms, and provider details.

What to Do When Moving

If you’re moving, first notify your provider of your new address and ask them to verify whether they can provide the agreed-upon service there. In Germany, there’s a special rule for telecommunications contracts: if your previous provider cannot provide the agreed-upon service at your new residence, you have the right to terminate the contract with one month’s notice.

If the provider can set up service at the new address, the contract is usually transferred. However, the terms, deadlines, and any relocation fees depend on the contract and the provider’s policies.

Common Mistakes

Choosing a plan based solely on the maximum speed advertised.
Don’t check the address before signing the contract.
Don’t forget about the price after the promotion ends.
Choosing a router that isn’t compatible with your connection type.
Signing a new contract without sorting out the old one.
Providing an incomplete apartment address, which causes the provider to incorrectly assess availability.
Wait until moving day to place your order.

Quick Checklist

Check the availability of DSL, cable, fiber-optic, and mobile internet at your exact address.
Compare the total cost over the entire minimum contract term.
Clarify whether a technician is needed and when installation can take place.
Decide whether to rent a router or use your own compatible one.
Check the terms for moving and canceling your service.
Keep your contract summary, order confirmation, and correspondence with the provider.

FAQ

Is it possible to have internet installed before moving in?

Sometimes, yes—if the lease agreement has already been signed, the move-in date is known, and you can have the technician or equipment installed. In practice, it’s best to order internet service in advance, but you should coordinate the activation date with the provider.

Why is the internet faster or cheaper for your neighbors?

They might have a different provider, an old promotional contract, a different line, or access to technology that isn’t available in your apartment. Even within the same building, conditions aren’t always the same.

Can you cancel your internet contract early when you move?

This isn’t automatically the case with every move. A special right to terminate the contract arises if the provider cannot provide the agreed-upon service at the new address. If the service is available, the contract is usually transferred.

Is it worth getting the fastest plan?

Not always. For video calls, streaming, and working from home, stability, response speed, latency, and line quality are crucial. If the network in your building is overloaded, the maximum advertised speed doesn’t guarantee the best experience.
