What customers like about AVM FRITZ!Box 6820 LTE

  • Built-in 4G LTE modem with 3G fallback
  • Multiband modem picks available networks automatically
  • SIM slot with mini SIM
  • Gigabit LAN port for a wired device
  • Compact and light at 172 g
  • Parental controls included

What customers don't like about AVM FRITZ!Box 6820 LTE

  • Wi-Fi 4 only with up to 450 Mbps
  • 2.4 GHz band only, no 5 GHz
  • Single LAN port
  • No USB port
  • 4G only, no 5G

Verdict

Mobile internet arrives through a SIM slot on the FRITZ!Box 6820 LTE, which carries a 4G modem with 3G fallback. The multiband modem picks an available mobile network automatically. Wi-Fi is old Wi-Fi 4 on the 2.4 GHz band only, with 3x3 streams and up to 450 Mbps. A single Gigabit LAN port connects one wired device. There is no USB port. Parental controls are included. At 172 g the box is small and easy to place. This mid-range model suits a holiday home, a worksite or a backup line where no fixed connection exists. Slow Wi-Fi 4 and the missing 5 GHz band make it a poor fit for streaming households. Buyers who need a faster mobile router should look at 5G or Wi-Fi 6 options.
