Put a giffgaff sim card in a o2 locked phone

[Anonymous]

Hi,

I am looking to change from o2 to giffgaff, but my o2 phone is locked to o2.

I know that giff gaff is owned by o2, so i wondered if you can put a giff gaff sim in a o2 locked phone. My phone is a sony ericsson xperia x8.

Thanks,

Elliott

Yes you can. My phone is locked to O2 and I've got a giff gaff sim card in it at the moment.

It would be highly ironic if it never, considering Giff-Gaff and Tesco mobile both lease the O2 network.
