"Individual customers whose monthly bill amount is Rs. 400 and above or bi-monthly amount is above Rs. 800 and above shall be earning loyalty reward point for every Rs. 50 for invoice paid within pay-by-date," BSNL said in a statement.
The reward points earned can be redeemed for making free calls within BSNL's network. The scheme has been launched with effect from April, 2013.
"BSNL has taken a lead in India by launching the loyalty scheme. The scheme of rewarding a loyal customer for their support to BSNL shall be helpful in retention of customers," BSNL CMD RK Upadhyay said.
BSNL said customers can redeem the points initially after six months from the date of earning loyalty point first time.
"Redemption will be in terms of free MCU (one point is equivalent to one free Metered Call Unit) which will be adjusted for calls made by customers on BSNL network (on-net calls) only," it said.
The redemption can be done in block of minimum 25 points and maximum 500 points, it added.
The scheme, however, would not be available to certain category of customers who are availing concessions in some other form.
As on December 2012, BSNL's landline subscriber base stood at 21.04 million and total internet connections (including broadband and narrowband) were at 13.09 million.
