It is certainly a proud moment for India that National Mobile Number Portability is implemented from 3rd July. The Department of Telecom has successfully rolled out the NMNP, involving 175 networks, across 22 circles. This allows customers to retain their mobile numbers, even if they move from one circle/state to another. Introduction of NMNP will surely increase customer satisfaction. BSNL has to improve it’s quality of service, to retain it’s customers.
