Configuring a mobile telephone number in the FRITZ!Box

When the FRITZ!Box is configured to access the Internet via the mobile network, you can also enter the SIM card's mobile telephone number in the FRITZ!Box and assign it to your telephones. Once you have finished setting it up, the telephone number is also used to make and receive calls when the Internet connection is established via DSL and not the mobile network.

Requirements / Restrictions

  • The mobile broadband dongle supports the "CSV" (Circuit Switched Voice) function.
  • The mobile telephone number assigned to the SIM card you are using has been enabled for voice.
  • Call diversions cannot be configured for mobile telephone numbers.

Important:Some of the settings described here are only displayed if the advanced view is enabled in the user interface. The configuration procedure and notes on functions given in this guide refer to the latest FRITZ!OS

1 Entering your location information

  1. Click "Telephony" in the FRITZ!Box user interface.
  2. Click "Telephone Numbers" in the "Telephony" menu.
  3. Click on the "Line Settings" tab.
  4. Select your country from the drop-down list under "Location Information". If your country is not included in the list, select "Other country".
  5. For the "Country code", enter the country code prefix in the first field and the country code in the second field (for example for Germany "00" and "49", see fig.).
  6. For the "Area code", enter the area code prefix in the first field and the area code in the second field (for example for Berlin "0" and "30", see fig.).

  2. Click "Mobile Communications" in the "Internet" menu.
  3. Enable the option "Telephony via mobile communications".
  4. Enter your mobile telephone number.
  5. Enter a name of your choice in the "Display name" field.

    Example:
    You could enter "Mobile_12345" as a display name for the number 017812345.

  6. Click "Apply" to save your settings.

Now your mobile telephone number will be displayed under "Telephony > Telephone Numbers" and you can assign it to your telephony devices.
