Simplified mobile communication device

An apparatus comprising:

• a processor device;
• a memory element including user authentication data and user identifier data;
• a short-range wireless network adapter;
• and
• device coordinator adapted to:
• detect a first communication device as substantially collocated with the apparatus using a short-range wireless network;
• establish a connection with the first communication device over the short-range wireless network;
• and
• communicate the user authentication data to the first communication device over the short-range wireless network to authenticate a particular user to the first communication device.

A method comprising:

• detecting a first communication device as substantially collocated with a second communication device using a short-range wireless network;
• establishing a connection between the first communication device and the second communication device over the short-range wireless network;
• receiving authentication data from the first communication device over the short-range wireless network;
• using the authentication data to authenticate a particular user to the second communication device;
• and
• sending a telephone number to the first communication device for use by the first communication device in establishing a telephone call with another device associated with the telephone number.

Logic encoded in non-transitory media that includes code for execution and when executed by a processor is operable to perform operations comprising:

• detecting a first communication device as substantially collocated with a second communication device using a short-range wireless network;
• establishing a connection between the first communication device and the second communication device over the short-range wireless network;
• receiving authentication data from the first communication device over the short-range wireless network;
• using the authentication data to authenticate a particular user to the second communication device;
• and
• sending a telephone number to the first communication device for use by the first communication device in establishing a telephone call with another device associated with the telephone number.
