System and method of sharing a contact list among mobile phones

A method of sending mobile phone contact list data from one mobile phone to another mobile phone is disclosed. The sender composes an SMS or MMS message having contact data from the mobile phonebook attached. The message is sent using a messaging service like SMS or MMS to other mobile phones in a group. Before receiving mobiles act on the message, a check is determined to see if the message contains contact list data. If it does not, the message is processed normally. If the message does contain contact list data, a software program is launched to manage the received contact list data. The program displays the received mobile phone contact list data so that the mobile phone user can examine the data. An import function is run to resolve conflicts, store and overwrite data into the mobile phone's contact database based on the newly received contact list data.
