Setting up the FRITZ!Box for use with a fiber optic connection from Odido (formerly T-Mobile)

The FRITZ!Box is optimally prepared for use with Odido (formerly T-Mobile). Simply connect the FRITZ!Box to the fiber optic connection, select T-Mobile Thuis as the internet service provider in the FRITZ!Box, and configure telephony.

The complete FRITZ!Box range of functions for internet, telephony, and smart home is then available to all of the devices in your home network without restriction.

Requirements / Restrictions

  • AON or GPON fibre optic connection. The FRITZ!Box cannot be used directly with XGS-PON fibre optic connections.

    NoteOn an XGS-PON connection you can configure the FRITZ!Box for the internet connection via 'WAN' and use it behind the fibre optic modem from the internet service provider.
