A system and process for updating files on a wireless mobile device is provided. The wireless mobile device has an RF(radio frequency) card which cooperates with a wireless network to provide wireless communication. In one example, the wireless network maintains a message contact list on a network server. The message contact list contains address information useful for sending textual, video, audio, or image messages through the wireless network. When the wireless mobile device is activated on the network, the message contact list is transmitted to the wireless mobile device. The wireless mobile device is then able to use the message contact list to generate and transmit messages.
