My hubby has an unlocked Sony Ericsson T630 that was originally on t-mobile. It was bought in the uk but over in Ireland he could only make calls & receive calls. None of the other functions like sms or mms or the wap browser would work even though he configured it to the vodafone or O2 settings depending on which sim card he used. Is this the price you pay for unlocking a phone???? Surely you don't lose what I'd call the most basic settings just because its been unlocked, or is it just sh*te t-mobile at its prime? Now back in the uk its still only making & receiving calls with no other function doh! Any help gratefully received, thanks.
