Last checked 15 October 2026.

How we worked it out

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

giffgaff 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: giffgaff only supports 4G calling on phones on its device list, which (as of late 2024) included no feature phones. Calls fall back to O2's 2G.
