ABSTRACT:
A mobile wireless terminal is configured to provide an audible alert to the user in the event of its receipt, while the terminal is on a call, of an indication of an imminent or directed handoff to a carrier or network which would charge the user for roaming. The call is automatically terminated or released within a predetermined time period after the audible alert unless the user performs an act of assent, such as pressing a predetermined key, or speaking a predetermined command, before the expiration of the time period.
