Setting up FRITZ!Box for Internet access via the mobile network (LTE/UMTS)

If you use an additional mobile broadband dongle with the FRITZ!Box, the FRITZ!Box can also connect to the Internet using the mobile network and then provide Internet access to all computers in the home network.

Note:If you do not have a mobile broadband dongle, you can also configure the FRITZ!Box to use the mobile Internet connection of an Android smartphone (USB tethering).

Requirements / Restrictions

  • The mobile broadband dongle must support the mobile standard LTE (4G) or UMTS/HSPA (3G).
  • The mobile broadband dongle must support the AT command set or USB tethering.
  • Depending on the mobile network operator, Internet telephony and all other functions for which a public IP address is required (for example incoming VPN connections) are either available or available only to a limited extent.

1 Connecting a mobile broadband dongle to the FRITZ!Box

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

    Important:The FRITZ!Box supplies USB devices connected to the USB port on the back with up to 900 mA, and to those connected to the USB port on the side with up to 500 mA in accordance with the USB specification. If the dongle requires more than this, connect it to the FRITZ!Box by means of a USB hub with its own power supply (active USB hub). Refer to the manufacturer of the dongle for information on its power consumption.
