Abstract
A method and system for maintaining a wireless carrier system presence at a vehicle telematics unit in a vehicle includes placing the vehicle telematics unit in a quiescent mode that suspends its signal transmitting functions; instructing the vehicle telematics unit to periodically exit the quiescent mode and transmit a query that determines if the wireless carrier system used by a telematics service provider has changed; when the wireless carrier system has changed, receiving a new wireless profile associated with a new wireless carrier system; and storing the new wireless profile in a universal integrated circuit card (UICC) hardwired at the vehicle.
