If you have an unlock phone and say for example you're now w. AT&T (cingular). Ofcourse your service will be provided from At&T, however sometimes there's gonna be a possibility that sometimes your service may upper under a different service provider. It's because all service providers sometimes borrows service for their customers from other carriers (roaming partners) if they don't have any coverage in the area, and that's what they call "roaming." However if you're question was say for example .. the phone turns on and it identifies Telstra when you turn the phone on just like when you have an at&t phone and phone identifies at&t when you turn it back on. It's only going to identify that service provider if phone cam from that service provider and unfortunately you can't change it.
