IDK about the roaming because mine sits here at my desk at work and will do it. My 6700 did it also. I do know it is communicating with the tower although IDK what it is communicating. There have been lots of threads about this in the past. Mine sometimes will also turn on and then go off when it times out and maybe come back on a few secs or even mins later and a TXT/MMS/VM will come through.

All I can say is although it may seem aggravating, it is a known occurance and 'somewhat' a normal one.
