You can quickly and easily check which DSL speeds are available at your location by entering your address details in our DSL availability check at the top of this website. Only the Internet and DSL tariffs with the corresponding available speeds will be displayed. This function replaces the Telekom DSL availability map.
The required bandwidth or DSL speed depends on your usage and the number of users:
A higher DSL speed always enables faster loading of web pages, smooth streaming and rapid uploads and downloads. If you start with a lower bandwidth, you can upgrade to one of the higher bandwidths free of charge at any time.
Our business DSL tariffs offer tailor-made solutions for start-ups, self-employed people and small businesses. We understand that every business has different requirements, which is why we offer a range of tariff options to meet your needs.
A fixed or static IP address ensures that your company website can always be accessed at the same URL and that your Internet-enabled devices communicate without errors. A fixed IP address is essential, especially if your company has multiple locations or if you work in different places (office, home office, branch office).
Curious? You can find more information about the advantages of our business tariffs with fixed IP addresses in our guide article "Fixed IP addresses as a success factor".
After you have carried out the DSL availability check, you will be shown how much bandwidth is available at your location. With DSL availability of up to 50 Mbit/s, you will automatically be directed to our Business Hybrid Start tariffs . With Hybrid 5G, additional data rates via mobile communications are added to the available bandwidth of your Telekom landline connection. This allows you to automatically add 5G/LTE mobile communications to your landline bandwidth and enjoy all the benefits of Hybrid 5G.
