Stuttgart – November 09, 2026 -- Many German households stuck in old internet contracts can switch to a cheaper plan on one month's notice, and the new provider handles the paperwork, according to consumer portal DSLWEB. Black Friday peaks on November 27, 2026, and more providers are already launching Black Week deals.
Many old contracts can be cancelled at any time
Since the 2021 reform of Germany's Telecommunications Act (TKG), internet contracts no longer renew automatically for another year once the minimum term, usually two years, has ended. They continue indefinitely instead and can be cancelled at any time with one month's notice.
The end date of a contract is listed in the customer account or the contract documents. Many providers also let customers sign the new contract now and schedule the switch for the end of the old term.
The new provider organizes the switch
Customers book the new plan and instruct the new provider to cancel the old contract during checkout. The existing landline number can usually be kept by stating that wish when booking.
In most cases, no technician visit is needed because the line can be switched remotely. That changes if the connection technology changes, for example with a first fiber-optic connection.
If the switch is ordered in good time at the same address, the old provider must generally keep service running until changeover. By law, service may be interrupted for one working day at most. For each additional working day, consumers are owed compensation of 10 euros or 20 percent of the monthly fee, whichever is higher.
DSLWEB editor Ingo Hassa advises keeping the confirmations from both providers and watching the switchover date.
Cheaper plans, faster speeds and bundles are on offer
Besides a lower price, shoppers can use the sales to upgrade to a higher speed or pick up a new router. Bundled plans that combine landline internet with TV and streaming are popular. Existing subscriptions can often be moved into the new package, so contracts once spread across several providers arrive on a single bill.
DSLWEB collects the deals
DSLWEB has compiled the best Black Friday offers for landline internet in one overview. Additional pages cover individual providers and products, from Telekom's tariff highlights to low-priced FRITZ!Box deals.
The portal also offers exclusive deals that add extras to selected offers, such as a special loyalty bonus or a free Netflix subscription. Hassa recommends comparing costs over the full contract term, since older contracts often hold considerable savings potential.
