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

With an additional mobile network dongle, the FRITZ!Box can also establish the internet connection via the mobile network. All you have to do is connect the mobile network dongle to the FRITZ!Box and enter the PIN in the FRITZ!Box user interface, and the complete FRITZ!Box range of functions for internet, telephony, and multimedia is then available to all devices in your home network without restriction.

Requirements / Restrictions

  • The mobile network dongle must support the mobile standard 4G (LTE) or 3G (UMTS/HSPA).

    Note:The 3G mobile network (UMTS/HSPA) has been switched off in Germany and many other countries.

  • The mobile network dongle must support the AT command set or USB tethering.
  • Depending on the mobile network provider, functions for which a public IP address is required (for example incoming VPN connections) are either not available 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 Connecting a mobile network dongle to the FRITZ!Box

  1. With the SIM card inserted, connect the mobile network dongle to a USB port on the FRITZ!Box.

    Important:According to the USB specifications, the power consumption of a USB device may not exceed 500 mA. If the dongle requires more than this, use a USB hub with its own power supply (active USB hub) to connect it to the FRITZ!Box. Refer to the manufacturer for information on the dongle's power consumption.

2 Configuring the internet connection in the FRITZ!Box

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Mobile Network" ("Mobile Communications") in the "Internet" menu.
  3. If the mobile network should always be used for the internet connection, enable the option "Internet connection via mobile networks enabled".
    • If the mobile network should be used for the internet connection when the internet connection fails, enable the option "Expanded Failover Protection / Fallback Mode for DSL/WAN".
  4. If the "PIN" field is displayed, enter the PIN for the SIM card in the mobile network dongle.

    Important:If you enter the wrong PIN three times, you must enter the PUK. Your mobile network provider can provide you with information on the PIN or PUK.

  5. If the drop-down list "Mobile network provider" is displayed, select your provider from the drop-down list. If your provider is not displayed, select "Other operator" and enter the account information you received from your provider in the corresponding fields.

    Note:You cannot change the account information for preconfigured mobile network providers.

  6. Click "Apply" to save the settings.

3 Configuring the mobile network dongle

The following steps are only necessary if a link to the user interface of the mobile network dongle is displayed in the FRITZ!Box user interface under "Internet > Mobile Network".

  1. Click "Internet" in the FRITZ!Box user interface.
  2. Click "Mobile Network" ("Mobile Communications") in the "Internet" menu.
  3. Click on the link to the user interface of the mobile network dongle.

    Note:You can also use the mobile network dongle's IP address to directly access its user interface, for example via http://192.168.10.20.

  4. Enable internet access in the mobile network dongle by entering the PIN for the SIM card in the user interface of the mobile network dongle. You can find information on configuring the mobile network dongle in its manual, or consult its manufacturer directly.
  5. If you received account information for internet access from your mobile network provider, enter the account information in the mobile network dongle.

The FRITZ!Box now establishes the internet connection using the mobile network dongle connected to it.

Note:If the mobile network dongle supports "CSV" (Circuit Switched Voice), you can also enter the SIM card's mobile telephone number in the FRITZ!Box and assign it to the telephones connected to it.
