Abstract
A method is disclosed for completing a roaming cellular call between a roaming subscriber and another party. The first step is initiating the roaming call between the roaming subscriber and the another party. The roaming subscriber is provided with a prepaid debit account. The roaming subscriber is then connected to a cellular network when a connection between the subscriber and the another party is to be made such that a call has been built over a calling network. The prepaid debit account of the roaming subscriber is then examined to determine the balance thereof, and then the roaming subscriber is informed of financial information regarding the call connection prior to connecting the roaming subscriber to the another party over the already built call.
