A control system for a vehicle includes a controller configured to send a mobile application part protocol (MAPP) message to the server requesting that further commands be sent via the MAPP. The control system may send the MAPP message responsive to receiving a message containing a wakeup command from a server and being unable to establish a packet switched connection with the server. The control system may start the vehicle responsive to receiving a MAPP message from the server containing a command to start the vehicle.
