What customers like about AVM FRITZ!Box 6825 4G

  • 4G modem up to 300 Mbps with 3G fallback
  • Wi-Fi 6 up to 600 Mbps
  • USB-C power from a charger or power bank
  • Alignment aid for best mobile reception
  • Failsafe backup behind an existing FRITZ!Box
  • Mesh support with WPA3 and WPA2
  • Compact housing that fits in a bag

What customers don't like about AVM FRITZ!Box 6825 4G

  • 2.4 GHz band only, no 5 GHz
  • 4G only, no 5G
  • Single Gigabit LAN port
  • No USB port
  • Wi-Fi capped at 600 Mbps

Verdict

Powered over USB-C from a charger or power bank, the FRITZ!Box 6825 4G travels easily. Its 4G modem reaches 300 Mbps and falls back to 3G, and a nano SIM slot takes the card. Wi-Fi 6 runs on the 2.4 GHz band at up to 600 Mbps. One Gigabit LAN port connects a wired device. Mesh support and WPA3 or WPA2 encryption are included. An alignment aid helps find the best spot for mobile reception. The router can also work as a failsafe behind an existing FRITZ!Box with a modem. There is no 5 GHz band and no USB port. This mid-range model suits holidays, campsites, hotel rooms and backup connections. Anyone who needs 5G speeds or several wired ports should choose another model.
