A communications device is disclosed. The communications device comprises a reader for reading a signal from a user, a communicator for generating a telephone call to a number, and a processor, in communication with the reader and communicator, which is adapted to instruct the communicator to call a specified number, dependent on the signal received by the reader. The device is switchable between a data call mode and an unanswered call mode. The specified number is dependent on whether the device is in the data call mode or the unanswered call mode, with the generated call to a specified number in the unanswered call mode not needing to be answered in order for one or more of the time of call, the originating number of the call or the number called to be detected, and the generated call to a specified number in the data call mode is intended to be answered.
