Does the Nokia 6310 (2021) work on Three?
No.
Doesn't workThis is a 2G-only phone and Three has no 2G network.
If you're on Three, pick another phone, or check the other networks below.
We worked this out from the phone's published bands and Three's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
Three (UK)
- 3G: Switched off (November 2025)
- 2G: Three has never had a 2G network, so calls need 4G Calling (VoLTE)
Nokia 6310 (2021)
- 2G: GSM 900 / 1800
- 3G: No 3G
- 4G bands: None (2G-only phone)
- 4G Calling: no – 2G-only, so no 4G Calling.
The same applies to networks that run on Three: SMARTY, iD Mobile. Smaller networks sometimes handle 4G Calling differently, so check with them too.
