Does the HMD 3210 4G work on Sky Mobile?
Works (on 2G)
Calls and texts work on Sky Mobile using 2G. They'll stop working when 2G is switched off unless 4G calling gets enabled.
How we worked it out
- 2G calls: The phone supports 2G and Sky Mobile's 2G network is still on (Sky Mobile uses O2's network).
- 4G bands: Shares 4G bands with Sky Mobile: B1, B3, B20, B28, B40.
- 4G calling: Sky Mobile only enables 4G calling on approved phones, and we haven't confirmed this one.
Sky Mobile runs on O2's network, so it uses O2's masts and bands.
About 2G: O2 plans to start switching off 2G in summer 2029.
About 4G calling: Sky only guarantees 4G calling on phones bought from Sky Mobile.
