The Supreme Court on Monday issued a notice to Centre and BSNL operators asking reply on plea seeking to quash an agreement for use of ‘outdated’ 2G technology in Arunachal Pradesh and two districts of Assam.

A bench of Justices Madan B Lokur and Deepak Gupta issued notices as the petitioner claimed that 2G technology was used in these areas despite the fact that telecom regulator TRAI and the DoT had themselves said it was outdated.

Meanwhile, the plea filed by NGO claimed that the outdated 2G network technology was procured at a huge cost while the 4G technology was availed at a cheaper rate.
