as in the telecalling and internet calling features provided by service provider, they will get the money by any means
for example if a user uses whatsapp call instead of ordinary call, he may be billed with his data usage and if not means in his main balance so totally the amount goes to the provider from main balance or data balance... what is the thing to afraid of
else if he uses a wi-fi connection there also the provider reduces the data count
so my point of view is ask to reduce the rates of data cards to make it easliy available to all sort of people
