Does the Cat B40 work on Bouygues Telecom?
It works, with caveats.
Works with caveatsWith 2G being switched off, calls and texts fall back to 3G, which this phone supports (900 MHz, 2100 MHz). Bouygues Telecom plans to switch 3G off at the end of 2029. We haven't found confirmation that 4G Calling works on Bouygues Telecom. 4G data should work (shared bands: 1, 3, 7, 20, 28).
Expect it to work, but read the switch-off dates below. That's where the catch is.
We worked this out from the phone's published bands and Bouygues Telecom's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
