I want to find out if my Samsung Galaxy i9300 is locked to O2 or not? I bought the phone from Tesco on an o2 (2 year) monthly contract which is coming to an end soon. I want to keep the phone for another 12 months, but I need to change the provider and use a Vodafone pay monthly SIM instead (so that I can get a signal in mid Wales). Help appreciated. Thanks.
