n259 · 41 GHz mmWave
n259 is a 3GPP 5G NR band (41 GHz mmWave), TDD duplex, uplink 39500–43500 MHz and downlink 39500–43500 MHz. It is millimetre wave: huge bandwidth and very short range, mainly for hotspot capacity. 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
- This is a TDD band: FDD-only modules cannot use it.
- 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 n259.
