How we worked it out

2G calls: The phone supports 2G and Tesco Mobile's 2G network is still on (Tesco Mobile uses O2's network).
4G bands: Shares 4G bands with Tesco Mobile: B1, B3, B20, B28.
4G calling: Tesco Mobile only enables 4G calling on approved phones, and we haven't confirmed this one.

Tesco 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: Tesco Mobile has a per-phone 4G calling checker.
