Method and apparatus for using text messages, e.g., SMS messages, to trigger a device update and/or to update a communications device, e.g., cell phone, are described. The cell phone can be updated/programmed from a remote device. The updating can use SMS messages to accomplish the update. An SMS message may include a command and, optionally, other update information in the message body. Received SMS messages are checked to determine if they include an update command. If an update command is present the command is performed after a security check is satisfied. In some but not necessarily all embodiments, a simplified user interface is supported in addition to SMS update features.
