Find the Mobile Service provider and location by a SMS by Reliance

Most of the time we  used to get a call or missed call, and we don't have any clue who has actually called us. Here is one of easiest way to track location and operator of mobile operator.

Send a SMS like this

 SERIES < mobile no> and send to 55500.

This SMS will be charged with Rs 3 by  operator. I have tested on Reliance

With the introduction of mobile portability this method will be effective to easily trace the  service provider and location.
