B85 · 700 Extended Lower SMH
B85 is a 3GPP LTE (4G) band (700 Extended Lower SMH), FDD duplex, uplink 698–716 MHz and downlink 728–746 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. None of the networks we check uses it.12

Who uses it
None of the networks we check uses it.
What it means for IoT devices
- None of the networks we check uses it; if your market is outside our coverage, go by the local operators’ own data.
Our dongles (MF833V, Dongle 400, F40) do not support B85.
