Setting up the FRITZ!Box for use with a mobile network

The FRITZ!Box Cable is ideally prepared for internet access via the mobile network. All you have to do is insert your SIM card into the FRITZ!Box and enter the PIN in the FRITZ!Box user interface, and then the complete FRITZ!Box range of functions for internet, telephony, and multimedia is available to all devices in your home network without restriction.

Requirements / Restrictions

  • The mobile network provider must support the standard 4G (LTE).
  • Depending on the mobile network provider, functions that require a public IP address (for example receiving incoming VPN connections) are either not available, only available with at home packages, or only available to a limited extent.

Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.

1 Inserting the SIM card into the FRITZ!Box

  1. Pull the card tray completely out of the SIM card slot (see fig.).
  2. Place the SIM card (mini-SIM, 25 x 15 x 0.76 mm) supplied by your LTE provider with the slanted edge in the bottom right corner with the contacts facing downwards. Do not use micro or nano-SIM cards that have already been punched out.
  3. Insert the card tray with the SIM card back into the SIM card slot.

    Important:If you are using the FRITZ!Box in an area located on the edge of LTE radio coverage, the two mobile network antennas included in the package may not be sufficient for a stable radio connection. In this case, use an outdoor antenna.

  1. Open the FRITZ!Box user interface.
  2. If the FRITZ!Box is set to factory settings, set a password for the FRITZ!Box user interface, and click "OK" and then "Next".

  5. Select your internet service provider in the drop-down list. If your internet service provider is not displayed, select "other internet service provider".
  6. Click "Next" and follow the wizard's instructions.
