the companies offering life paid will get hit back later
coz the main revenue in the case of prepaid is the processing fee they charges for each re-charge
if a person recharges 330 re charge card and he gets 150 rs talk time
As the person can call 83 call units @ 1.8/min
and for this 83 call units customer pays 330 rs ... net call charges will b Rs 3.97/min
the operators cost around 80 paisa the balance is the profit for the operators
by avoiding this operators will face a huge revenue cut soon
