AT&T's US 20150156604: LOCATING A DEVICE VIA A TEXT MESSAGE
A first device may receive a location of a second device simply by sending a text message to the second device. The text message may comprise an identifier of the second device (e.g., phone number of the second device, mobile subsection identification number of the second device, etc.) and a location code. A communication network may intercept the text message. The communication network may analyze contents of the text message. The network may determine that the location code is valid and determine the location of the second device. The network may provide an indication of the location of the second device to the first device.
