Hi all, I've got the sony ericcson satio, and to block international calls you need the barring code, all i know is its 4 digits because if i try to add any more digits on it doesnt let me, I'm aware that service providers have different codes, but T-mobile is impossible to find out for, so if anyone knows it, it saves me the hassle of having to call 150 and wait forever for a very unhelpul person to speak to me, thanks
