The ongoing ban on bulk SMSes across India is not only causing troubles for mobile phone users by affecting festive spirits, but also causing revenue losses to telecom operators.

Indian authorities put a 15-day ban on bulk SMSes and MMSes starting August 18, in wake of use of these services to spread hate material that led created a fear psychosis among Northeast Indians, leading to their mass exodus from different parts of the country.

Under the directive of the Telecom Regulatory Authority of India (TRAI), carriers are not allowing mobile phone users to send more than five SMSes or MMSes in a day, even if the user sends it to multiple users or to one user.

The surely affected the festival spirit of mobile phone users during the Parsi New Year, Eid and Onam as they could not wish all of their friends and relatives on the festivals.

Director General Rajan S Mathews, of Cellular Operators Association of India (COAI), said that ban is also affecting the revenues of mobile phone operators.

Speaking on the topic, Mathews said, "A ban of 15 days means they could lose around seven to eight per cent of revenue this month from this service alone."

However, Mathews emphasized that all the members of the COAI would definitely keep on abiding by the rules, as human lives and national security are at stake.

India authorities have claimed that hate messages were being uploaded by unknown individuals or groups from Pakistan.
