A system and method are provided that enable a mobile device when out-of-coverage and thus unable to send or receive messages to rely on other mobile devices which are also out-of-coverage as 'hosts' for their outgoing messages such that when one of the hosts comes back into coverage the host mobile device (HMD) can send the outgoing messages on behalf of the originating or 'source' mobile device (SMD). The system and method may comprise a pairing procedure to determine the suitability of a mobile device being an HMD according to criteria such as battery power, memory availability and whether the device is also out of coverage. When coming back into coverage, information is obtained from the data communication system to determine whether others have already sent messages that have been provided to host mobile devices.

System and method for enabling messages to be sent while a mobile device is out-of-coverage

System and method for delivering messages to devices not in communication with a transmitting server. One or more wireless devices serve as host devices to relay a message from the server to the target device that is not in communication with the server. The server sends the message to host devices when they are in communication with the server. The host device or devices store the message to be relayed to the target device. When the host device is close to the target device, it establishes a short range wireless link with the target device and transmits the message to the target device. In an example, the messages sent to and stored by the host device are encrypted so they are not able to be read by a user of the host device.
