The Supreme Court today set up a joint expert panel to recommend the procedure for the telecom firms for properly identifying the customers before issuing SIM cards to them. A bench of Chief Justice S H Kapadia said the panel comprising officials of the Department of Telecommunications and the Telecom Regulatory Authority of India will submit its report to the government within three months. The bench passed the order on a plea by a petitioner seeking its direction to the government to frame guidelines for telecom firms for issuing SIM cards.
