Does the Cat B40 work on Three?

Last checked 23 Oct 20264 sourcesWorked out from published specs

Yes.

Works

Calls and texts work over 2G, which Three keeps running with no switch-off date announced, and 4G data should work (shared bands: 1, 3, 20, 28).

Calls, texts and data should all work with a Three SIM.

We worked this out from the phone's published bands and Three's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
