Q: Does the Nokia 800 Tough work on O2 (Telefónica)?

Works with caveats. Calls and texts can fall back to 2G. O2 switches 2G off in the second half of 2028 and asks people to replace 2G-only devices by 1 July 2028. We haven't found confirmation that 4G Calling works on O2 (Telefónica). 4G data should work (shared bands: 1, 3, 7, 8, 20).
