B33 · 1900 IMT TDD
B33 is a 3GPP LTE (4G) band (1900 IMT TDD), TDD duplex, uplink 1900–1920 MHz and downlink 1900–1920 MHz. It is a capacity layer: wide and fast, with shorter reach than the low bands. 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 B33.
