One must understand that telecom operators get an average of their 15-18 per cent of their revenue from data services of which SMS is a part.
Now with a ban of 15 days on sending sms, it is going to have a grave impact on the revenue of these telecom companies as they could lose around seven to eight per cent of their revenue this month from this service alone,
This data is authentic as it comes from the horses mouth and this time the source of the report is Cellular Operators Association of India (COAI).
Generally it makes sense to have a post paid connection as such type of sms ban generally gets applied to pre paid clients and rarely affects post paid clients.
