A method of activating a device involves establishing communication between the device and another device and receiving, at the other device, a message including activation information from a third party facility. The activation information includes a header and a mobile dialing number. The method further includes using the header to identify the message as an activation message for the device and, via the device, retrieving the identified message from the other device. The mobile dialing number is stored in a memory associated with the device, where the mobile dialing number enables the third party facility to initiate communication with the device.
