The regulator had earlier put the cap at 100 SMS a day in a bid to tackle unwanted messages sent by telemarketers. The new change comes after various user groups expressed concern at the cap.
"The authority has received representations from some of the service providers and consumers to increase the limit of 100 SMSes per day per SIM. The authority has considered these representations and decided to increase the limit of 100 SMSes per day per SIM to 200 SMSes per day per SIM," TRAI said in a statement on Tuesday.
The new cap of 200 SMSes per SIM per day will be effective from Today.
