Systems and methods for mobile connectivity provisioning at an access network are described. The access network has a service connection to a service center that is external to the access network. The method includes receiving, from a mobile vehicle, an indication of a connection request for a device on the mobile vehicle. The connection request identifies the device using a media access control (MAC) address. The method includes generating a globally unique identifier (GUID) associated with the MAC address and transmitting a first message comprising the GUID to a network access terminal on the vehicle. The network access terminal redirects the connection request to the service center via a traffic connection. The redirected connection request includes the GUID. The access network receives an indication of a network service for the device from the service center; the indication identifies the device based on the GUID.
