Now, Indian mobile phone users will be able to keep their number even when they’re moving to another state by April 2014. The Telecom Regulatory Authority of India (TRAI) had already mandated mobile phone companies to implement full mobile number portability within six months.
At present, Mobile Number Portability (MNP) is restricted within a service area. For example, a Tata Docomo subscriber from Kerala circle can port his mobile number to another service provider within Kerala only.

Pan-India MNP will allow the subscriber to move to any other circle like Delhi or Maharashtra, even to another service provider, without changing the mobile number.
