Does the Cat B40 work on EE?
It works, with caveats.
Works with caveatsCalls and texts can fall back to 2G. EE starts switching 2G off from May 2029. We haven't found confirmation that 4G Calling works on EE. 4G data should work (shared bands: 1, 3, 7, 20).
It works today, but calls on the Cat B40 rely on a part of EE's network with a switch-off on the way. Check the dates below before you commit for years.
We worked this out from the phone's published bands and EE's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
