In that case user have to call home and ask someone to search for that contact and then resend it back. Instead of doing this tedious process one can send an SMS from someone’s cell to his/her own mobile in a predefined syntax: get contacts. The contact name which you wish to get should write the way it is saved in his/her contact list. If one want multiple contacts, then send the initial of the contact name along with the syntax and the application will return all the contacts starting from that initial. Also get particular date’s inbox SMS can be retrieved using this application.

Similarly, the messages that are received in the user’s mobile can be retrieved for a particular date. The application also helps an alert service which can be remotely activated. Once the alert service is activated the application enters into retrieve hearing mode. When the user mobile receives a missed call an alert message will be sent to the remote mobile from which the service has been activated. Password based authentication is included to authenticate the owner of the mobile. Security is provided using this mechanism. The alert service also sends notifications to remote mobile if the battery percentage goes down the limit.
