B103 · 700 Upper SMH (NB-IoT)
B103 is a 3GPP LTE (4G) band (700 Upper SMH (NB-IoT)), FDD duplex, uplink 787–788 MHz and downlink 757–758 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

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 B103.
