B71 · 600 (US)
B71 is a 3GPP LTE (4G) band (600 (US)), FDD duplex, uplink 663–698 MHz and downlink 617–652 MHz. The whole band sits below 1 GHz, so it is a coverage layer: it travels far and gets through walls, deciding rural and indoor signal. Of the 155 networks we check, 1 use it (United States).12

What it means for IoT devices
- For IoT devices headed to United States, support B71: it is a coverage layer, and without it indoor and rural signal drops noticeably.
Our dongles (MF833V, Dongle 400, F40) do not support B71.
