Anyone help me with a small query? Had an android phone unlocked from O2 then put a Three number in and used for 12 months. I have now finished with them as I got a Iphone but would still like to use the android as second phone, I have tried putting a orange sim card in but it says network locked.
Does this mean I have to get the phone unlocked again from Three even though it was a pay as you go sim with them?

Cheers

Hm.

Far as I know, it’s either it’s operator locked, or it isn’t. Unless O2 have unlocked it from O2 and re-locked it to 3 I suppose, which seems unlikely at best. Very odd.

Do you know for sure that the Orange SIM actually works ok?
