Nationwide Mobile Number Portability is expected to be rolled out by February 2013. This will allow mobile subscribers to retain their numbers even when they shift to a different telecom circle. This was announced by the Telecom Minister Kapil Sibal at the ‘India Telecom 2012’ in New Delhi.
Currently, a user is allowed to switch to a different operator within his/her circle, while retaining his/her phone number.
India has 22 telecom circles. According to TRAI, by the end of October 2012, about 75.14 million subscribers have submitted their requests to different service providers for porting their mobile number.
