Setting up FRITZ!Box for use with a Telekom DSL line
You want to set up the FRITZ!Box on a Telekom line with IP telephony, for example MagentaZuhause? ✔ It's easy with this step-by-step guide.

The FRITZ!Box is optimally prepared for use with Deutsche Telekom (for example 'MagentaZuhause', 'MagentaEINS'). Simply connect the FRITZ!Box to the DSL line and enter your personal account information in the FRITZ!Box user interface.
The complete FRITZ!Box range of functions for internet, telephony, and television (MagentaTV) is then available to all of the devices in your home network without restriction.
Requirements / Restrictions
- Use of a VDSL supervectoring line (for example 'MagentaZuhause XL') is not supported.
Note:You can find information on FRITZ!Box models that support supervectoring in our product overview.
1 Having your account information ready
- Have your personal account information that you received from Telekom ready.
Note:You will find the account information in the letter that Telekom sent you before activating your connection. If you did not receive your account information, contact Telekom.
