B27 · 800 SMR
B27 is a 3GPP LTE (4G) band (800 SMR), FDD duplex, uplink 807–824 MHz and downlink 852–869 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 B27.
