Internet / Mobile Communications

The FRITZ!Box can also make the internet connection available via a mobile network connection. The mobile network connection can be established with the following mobile communications devices:

  • via a USB mobile communications dongle in modem operation with LTE/UMTS/HSPA support
  • by a mobile communications dongle in USB tethering mode
  • by a smartphone in USB tethering mode (only smartphones with Android 4.1 or higher)

Note:The "Internet / Mobile Communications" menu is visible in the user interface of the FRITZ!Box only when a mobile communications device is inserted in a USB port on the FRITZ!Box.

Click the "Apply" button to save your settings. If you leave the page without saving, all of your changes will be discarded.

If the FRITZ!Box connects to the internet over the mobile communications network, it depends on the mobile carrier whether the following FRITZ!Box functions can be used:
- internet telephony
- incoming VPN connections
- MyFRITZ!
- other connections requiring a public IP address

USB Tethering

Select how the internet connection via a mobile network should be used. Choose from the following options:

Internet connection via smartphone or mobile communications dongle by USB tethering enabled

Select this option if the internet connection should be established only via the mobile network.

Note:If you want to use the online counter of the FRITZ!Box for the mobile communications connection and have used a different internet connection to date, reset the online counter under the "Internet / Online Monitor".

Enable the option "Internet connection via smartphone or mobile communications stick by USB tethering" automatically whenever the DSL connection is interrupted

Select this option if the internet connection should automatically be established via the mobile network only when the DSL connection is lost. As soon as the DSL connection has been stable for at least 30 minutes, the FRITZ!Box will return to using the DSL connection and end the mobile communications connection.

Internet connection via smartphone or mobile communications dongle by USB tethering disabled

Select this setting if the mobile network connection should not be used for connecting to the internet.

Internet Telephony via the Mobile Internet Connection

If you registered internet telephone numbers in the FRITZ!Box "Telephony / Telephone Numbers / Telephone Numbers" menu, then you can use the internet telephone numbers via the mobile network connection.
