Will my iPhone 5 be locked to O2

[Anonymous]

Considering joining Vodafone at end of contract. 2 questions: will my iPhone 5s be locked to O2, is there a chance 02 would match the 15% discount on a contract I can get elsewhere?

Have you tried another non uk SIM card in it ?

Did you get the iPhone with your contract through O2 ?

To be clear,

If you got the phone from O2 it's locked

If from an independent it's likely to lock to the first network sim used

If you got it from Apple it won't be locked unless you took out an O2 contract through them.

Either way, do as suggested above and fill in the unlock form.
