Does the Nokia 6310 (2021) work on O2?
It works, with caveats.
Works with caveatsCalls and texts work over 2G, but this is a 2G-only phone with no 4G. O2 plans to start switching 2G off from 2029, and then it will stop working.
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 O2's own published network facts (see How we check). Nobody has confirmed it for this exact pairing yet.
O2 (UK)
- 3G: Switched off (completed 2025/26)
- 2G: Staying on for now; O2 plans to begin switching 2G off from 2029
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 O2: giffgaff, Tesco Mobile, Sky Mobile. Smaller networks sometimes handle 4G Calling differently, so check with them too.
Other networks in the UK
- EE Works with caveats
