A computer-implemented method for sender activated mobile call overloading (SAMCO) is described that includes processors configured for receiving request call data comprising a data request initiated by a sending mobile device intended for a receiving mobile device, receiving active call data corresponding to a telephone call placed by the sending mobile device to the receiving mobile device, wherein the active call data comprises the data request, determining that the receiving mobile device is subscribed to a data request service configured to execute the data request, determining that the sending mobile device is authorized to access the receiving mobile device, and responsive to determining that the sending mobile device is authorized, the method includes processors configured for transmitting the data request to the receiving mobile device.

An electronic messaging device includes a receiver configured to receive a message at one of a first operational frequency and second operational frequency. The messaging device can added to a message distribution group comprising a plurality of existing messaging devices. A test communication can be sent through a coupling to test an operation of the messaging device and confirming the addition of the messaging device to the message distribution group without communicating with the existing messaging devices.

A vehicle messaging method (600) and system (100) can include any number of data sources (101-103), an interface (104) that formats messages and addresses from the data sources, and a corresponding number of messaging servers (111-113) that receive targeted messages intended for a predetermined subset of subscribers associated with a vehicle identification number (VIN). Each messaging server can include a corresponding controller (121-123) programmed to assign (604) targeted messages to a predetermined channel and encode (606) the addresses of the targeted messages to the predetermined subset of subscribers using a VIN or portion thereof. The controller can be further programmed to transfer (608) the targeted messages and addresses to a satellite uplink (107) and satellite (110) via a messaging uplink interface (106) for retransmission and reception by a plurality of selective call receivers 109 addressable individually using a predetermined VIN or portion thereof.

A first user device may be included in a user device group including the first user device and a second user device that share a same service identifier for a communication service. The method may include accepting user input at the first user device to activate an operation mode for the first user device. Responsive to accepting the user input to activate the operation mode at the first user device, the operation mode may be activated at the first user device. Responsive to accepting the user input to activate the operation mode at the first user device, a notification regarding activation of the operation mode may be transmitted to a control server that is remote from the first user device. Related user devices and control servers are also discussed.
