The Telecom Regulatory Authority of India, or TRAI, has recently announced that every mobile phone user in India will only receive whitelisted links via SMS, any unapproved web links via SMS will be automatically blocked. The deadline for the implementation has been extended by one from the telecom regulators, meaning that, from October 1 onwards, if you receive any SMS, it will be a whitelisted one which is approved by the TRAI.
