First Reliance Mobile Number is similar to the number of Home Phone numbers bearing only 7 digits. Reliance Number of those days wef 3rd JULY 2003 was 3121928. Lanching of the new office and distribution of the mobile sets was controlled by the police force on the day at Vahuthacaud, Thiruvananathapuram. The last piece was procured by me on the same day. IT CHANGED DUE TO THE TRAI'S COMPULSION CHANGED TO 9387821928 wef- bearing 10 digits similar to all other mobile numbers. Till today the connection is along with me for the last tedious 10 years.
