Indian telecom operators have started the process of removing the 0 and 91 STD prefix for dialling a mobile number.
The technical changes seem to have rolled out by operators this week; we tested this on Vodafone and Airtel numbers based out of Delhi and are getting reports of the rollout from other parts of the country as well.
The changes are in compliance with DoT’s (Department of Telecom) deadline on implementation for full mobile number portability (MNP), which was extended by two months from May 3 earlier this month.
The DoT had approved TRAI’s recommendations on MNP on November 2014, and had fixed an implementation deadline of six months.
Full MNP will allow subscribers to retain their mobile number in any part of the country even when they change their operator or state. At present, MNP allows subscribers to change mobile network while retaining their number in the same telecom circle.
Telecom operators will be spending around Rs 200-300 crore to upgrade their networks to implement full MNP across India, reported Business Standard.
TRAI had reported a total telephone subscriber base of 996.49 million users at the end of March 2015, out of which a 3.84 million subscribers had submitted their requests for mobile number portability.
