Does the Light Phone III work on SFR?

Q: Does the Light Phone III work on SFR?

Works. Light's own compatibility checker says the Light Phone III will work with SFR in France (it lists Orange, SFR, Bouygues and Free; checked 23 Oct 2026). Light's spec sheet lists 4G and 5G only, so calls go over 4G Calling and the 2G switch-off doesn't change anything for it.

Yes, it should.

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

Light Phone III

2G: Not listed on Light's spec sheet
3G: Not published or not checked yet
4G bands: 1, 2, 3, 4, 5, 7, 8, 12, 13, 14, 17, 18, 19, 20, 25, 26, 28, 29, 30, 38, 40, 41, 42, 48, 53, 66, 71 + 5G
4G Calling: unknown – Light says the Light III is one worldwide model, but we haven't found a UK or Portuguese network that confirms 4G Calling on it. EE owners on r/LightPhone report 4G service.

The same applies to networks that run on SFR: RED by SFR. Smaller networks sometimes handle 4G Calling differently, so check with them too.
