Both the handset and the base station "handle" hand offs. The handset has a programmed minimum signal level, below which it will essentially request a hand off if one is available. The network can switch the handset to another tower for load balancing or other reasons if it determines that the handset (or the carrier's business interests) is better served by another tower. It's a two way system. If the network wants to move you on to another tower, but the phone won't get a lock, you stay on the original tower.
The problem with the OP is that his SIM (which is programmed with carrier preferences) keeps pushing him off roaming and into the actual AT&T network. Basically, AT&T has its network set up so that any level of AT&T signal is preferable to any level of roaming. It does that to save money on roaming costs, since AT&T handles you for free while you're on their system, but has to pay a few cents to have the roaming partner host you.

Former AT&T employee. They suck. You have no idea how much they suck. In fact, I should probably change my s/n, since I haven't even used them in 3 years.
