Communication system and method for multiple devices

A mobile communication method comprising:

• assigning a single phone number to a plurality of mobile communication devices equipped with voice and data communication capability over a wide area wireless network including a cellular communications network,
• receiving and sending voice calls and data to and from said mobile communication devices using solely said single phone number, wherein said plurality of mobile communication devices access the same user data, and wherein contacting said single phone number directly contacts all of said plurality of mobile communication devices;
• wherein upon receiving an incoming call to said phone number, said network sends the call request to all said devices, and wherein upon a call getting picked up by a user on any of said devices, the network drops the call request to all other devices, wherein upon placing or receiving a call on any one mobile communication device in said plurality of mobile communication devices, disabling all other said mobile communication devices from performing mobile communications for the duration of the call, forming a dedicated and private channel for each said call,
• assigning a unique identifier to each mobile communication device of said plurality of mobile communication devices to uniquely identify each of said mobile devices from other mobile devices in said plurality of mobile communication devices having the same single phone number, and embedding each of said unique identifiers in each of the respective mobile devices.

A mobile device comprising:

• a core engine communicatively coupled with a plurality of subsystems, the core engine surrounded by a housing unit and configured to coordinate the operation of the mobile device, the housing unit at least partially enclosing and holding together at least one of the plurality of subsystems, wherein at least two of the plurality of subsystems have wireless communications capability configured for voice and data wireless communication over a wide-area wireless network including a cellular communication network, wherein at least one of said wireless communications subsystems is detachable from the housing unit, wherein the mobile device having an assigned single phone number that is assigned to said wireless communications subsystems, wherein said wireless communications subsystems have access to the same user data and receive and send voice calls and data using solely said single phone number, wherein calling said phone number directly contacts all of said wireless communications subsystems, wherein upon receiving an incoming call to said phone number, said network sends the call request to all said subsystems, and wherein upon a call getting picked up by a user on any of said subsystems, the network drops the call request to all other said subsystems, wherein upon placing or receiving calls on each one of said subsystems, all other said subsystems are disabled from performing mobile communications for the duration of that call, forming a dedicated and private channel for each said call, wherein each wireless subsystem is assigned a unique identifier to uniquely identify each of said subsystems from other said wireless communication subsystems having the same single phone number in said wireless network, and wherein each of said unique identifiers is embedded in each of the respective subsystems.
