Does the Cat B40 work on NOS?

Last checked 22 Oct 20264 sourcesWorked out from published specs

Yes.

Works

Calls and texts work over 2G, which NOS keeps running for voice now 3G is gone, and 4G data should work (shared bands: 1, 3, 7, 20).

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

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