The Telecom Regulatory Authority of India, TRAI, in its latest directive has set the limit for concessional SMS at 100 per day per SIM. This has to be implemented within 15 days. According to the latest measures, there is no maximum limit for SMS, but consumers will be charged not less than 50 paise per SMS once it crosses 100 a day to restrict unregistered telemarketers from sending bulk promotional SMSs using machines. TRAI has also asked the providers to work out a solution within the next three months. The solution will ensure that not more than 200 SMSs with such similar signature are sent in an hour. An official statement said that, however, registered telemarketers, transactional message sending entities and telephone numbers exempted by the Authority are excluded from this provision. Normal consumers sending non-commercial SMSs will also not be affected by this measure. A complaint can be registered through SMS by forwarding the spam SMS to 1909.
