The Telecom Regulatory Authority of India (TRAI) has exempted the daily SMS limit of 200 for machine to machine and person to machine messages. TRAI restricted mobile users from sending more than 100 SMS / day per SIM starting 27th September 2011, to prevent pesky marketing SMS. Later they increased the limit from 100 to 200 SMS / day per SIM.
TRAI exempted the limit for these business houses after they received representations from the stakeholders that they were not able to send machine to machine and person to machine SMSs which are sent by them to initiate process or application for their operational requirements.
These services include providing details of driver or taxi on booking of Radio Taxi, tentative date of delivery of goods, tentative date of attending complaint, contact details of person attending the complaint etc
