TRAI issues Directions On Blocking of SPAM Bulk International SMS
New Delhi, 20th January, 2012:
Several incidences came to the notice of TRAI that promotional SMS were being routed through the servers located at international destinations and were getting delivered to customers registered in NCPR. It was observed that generally such SMSs were getting originated from locations within Germany, Sweden, Nauru, Fiji, Cambodia, Bosnia, Albania, Grenada, UK, Jersey, Sint Maarten, Tonga, Vanuatu, Namibia, Panama, Antigua and Barbuda etc. These SMSs contain the headers which are alphanumeric or starting with +91 or numbers with international codes.
TRAI today issued a direction to all Access Providers and International Long Distance Operators for blocking the bulk international SMS and to take the following steps within thirty days.
All international SMS containing alphabet header or alphanumeric header or +91 as originating country code should not be delivered through the network.
If any source or number from outside the country generates more than two hundred SMS per hour with similar ‘signature’, the same should not be delivered through the network. However, such restriction shall not be applicable on blackout days.
Only valid codes associated with the network of those entities with whom agreements have been signed by the Access Providers shall be allowed in the network.
