Patent ID: 8515384

Claim:
A method for activating wireless data communication service, the method comprising steps of: receiving a first wireless call by a data device lacking a pre-assigned mobile directory member (MDN) to a network service provider without using a MDN for the data device, the first wireless call using a network access identifier (NAI) that is exclusive to the data device, the NAI supporting only communication service access for service provisioning with the network service provider; establishing payment to the network service provider for data communication service for the data device, during the first call; assigning a MDN for authorized data communication for the data device by the network provider for a pre-set service time period; terminating the first call; receiving a second wireless call by the data device to the network service provider using the NAI; receiving an authorization code entered by the data device; responsive to the authorization code entered by the data device, downloading the assigned MDN from the network provider to the data device, to provision the data device to use the assigned MDN for authorized data communication for the pre-set service time period, wherein the pre-set service time period commences after the downloading; sensing when initiation of an additional data call occurs; determining whether the sensed additional data call initiation occurrence is within the pre-set service time period; upon determining the sensed additional data call initiation occurrence is within the pre-set service time period, connecting the additional data call for network communication; and upon determining the sensed additional data call initiation occurrence is outside the pre-set service time period but within a grace time period in excess of the pre-set service time period, reauthorizing use of the assigned MDN by the data device for connecting the additional data call for network communication.
