ABSTRACT:
In a system including a telematics unit and a data center, a method for automatically replenishing pre-paid calling units within the telematics is based on an occurrence of a trigger event as detected by the telematics units. Upon being notified of the trigger event, the data center automatically uploads a replenishment package to the telematics unit or uploads a replenishment package selected by the telematics unit.
