3 Huawei E3372h-320 is not supported
The mobile broadband dongle E3372h-320 from Huawei cannot be used with the FRITZ!Box's USB port because this mobile broadband dongle does not support all of the common AT commands and can therefore not be controlled by the FRITZ!Box.
4 Vodafone K5006-Z is not supported.
The mobile broadband dongle MF821 from ZTE, marketed under the name K5006-Z by Vodafone, cannot be used with the FRITZ!Box's USB port. This mobile broadband dongle only supports the proprietary QMI protocol (Qualcomm MSM Interface) and not the PPP protocol required by the FRITZ!Box.
5 Samsung GT-B3740 is not supported
Samsung's mobile broadband dongle GT-B3740 cannot be used with the FRITZ!Box's USB port because Samsung designed this LTE dongle for use with manufacturer-specific interfaces. This is not an error on the part of the FRITZ!Box, this is due to technical reasons on the part of the Samsung dongle.
Note:Some mobile network operators (for example Vodafone) offer the LTE dongle GT-B3740 under their own name. The FRITZ!Box recognizes the LTE dongle GT-B3740 as a USB storage device.
6 D-Link mobile broadband dongles are not supported
Mobile broadband dongles from D-Link (for example DWM-222, DWM-221, DWM-157) cannot be used with the FRITZ!Box's USB port due to technical aspects of these sticks.
