Overview
The FRITZ!Box 6850 5G is a cellular router from AVM that uses a nano-SIM for mobile broadband instead of a fixed line connection. It supports 5G and 4G LTE, Wi-Fi 5 dual-band wireless, and includes a built-in DECT base station for cordless phones.
Who it suits
This router is suited to homes without a fixed broadband line that want to use a mobile SIM for internet access. It also fits households that want a DECT base station for cordless phones alongside their router.
Reasons to consider it
It takes a single swappable nano-SIM and supports 5G including mmWave along with 4G LTE and international roaming, giving flexibility for mobile network use. Four Gigabit Ethernet ports allow wired connections for multiple devices, and the built-in DECT base station adds phone functionality without extra hardware.
Limitations and compatibility checks
There is no 6 GHz band support, so it runs on Wi-Fi 5 with 2.4 and 5 GHz only. It has no USB port, no PoE, and no wired backhaul support, and it relies on AVM's own FRITZ! Mesh ecosystem rather than working across other mesh brands.
