I've been using my unlocked SMT5600 in the USA on Cingular for almost 2 years. It was originally an AT&T phone. I've just moved to Scotland and I now have a Vodafone SIM that I've been trying to use with it. The Cingular SIM will pick up the O2, and Orange networks and works just fine for making local and international calls, but that SIM will be cancelled soon. When I install the Vodafone SIM, the phone boots fine, but searches for a network and never finds one.
The phone is both network and application unlocked. What am I doing wrong? Any help is greatly appreciated, as I love this phone. I'm kind of lost without it.
