1. A wireless communication device comprising:
- a) memory;
b) a processor;
c) a wireless modem configured to communicate on a first wireless network and a second wireless network, wherein the first wireless network is slower than the second wireless network; and
d) a network switching application configured to manage connections of the wireless modem, wherein the network switching application is configured to automatically direct the cellular modem to terminate a first connection to the first wireless network and establish a second connection to the second wireless network while the wireless modem is connected to the first wireless network when the network switching application determines that the second connection to the second wireless network is available based on stored information associated with network coverage area of the second wireless network, wherein the network switching application utilizes information associated with network coverage areas of the first wireless network and the second wireless network to manage the connections of the wireless modem to the second network and the first wireless network, wherein the information for the network coverage areas of the first wireless network and the second wireless network is stored within a geo-fence polygon entry, wherein each geo-fence polygon entry contains the information for portions of the network coverage areas found within a corresponding geo-fence polygon.

19. A method of automatically monitoring and controlling connections of a wireless modem of a wireless communication device between a first wireless network and a second wireless network, the method comprising the steps of:
-
a. determining if the wireless modem is connected to the second wireless network; b. determining if the second wireless network is available if the wireless modem is not connected to the second wireless network based on stored information associated with network coverage area of the second wireless network by utilizing information associated with network coverage areas of the first wireless network and the second wireless network, wherein the information for the network coverage areas of the first wireless network and the second wireless network is stored within a geo-fence polygon entry, wherein each geo-fence polygon entry contains the information for portions of the network coverage areas found within a corresponding geo-fence polygon; c. directing the wireless modem to connect to the second wireless network if the second wireless network is available and the wireless modem is connected to the first wireless network; and d. directing the wireless modem to connect to the first wireless network if the second wireless network is not available. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
