My question is can a phone be unlocked only to a certain amount of networks?
Is it either locked into one network only or open to all networks once an unlocking code has been used on it?
I'm asking because I have just bought a Samsung D600 on E-Bay which the previous owner says is unlocked, but when i insert my Tesco mobile sim card it only allows limited service i.e. emergency calls only
It gives me the choice of four networks to pick manually - O2, Vodafone, Orange and T-Mobile, does this mean it has been unlocked but will only work with any of these four networks?
Is it worth me trying to get it unlocked again or is it that Tesco mobile is rubbish?
thanks for any info on this it's my sons new phone and he is most upset that he can't get it to work properly,
thank you
