Mobile Number Portability in India
Mobile Number portability allows mobile subscribers to retain their phone numbers even if they change service providers. India had over 670 million mobile subscribers at the end of August 2010, according to the Telecom Regulatory Authority of India (TRAI).
Under guidelines proposed last year by TRAI, mobile users will be allowed to use the same mobile number even if providers use different mobile technologies like CDMA (code division multiple access) or GSM (Global System for Mobile Communications).
In short – Under this plan, customers intending to shift to a new service provider should send an SMS to 1900, from where they will get a unique porting code. They should then fill in an application form of the new service provider.
The service provider will 'Port' the 10 digit number to the telecom company of the subscriber's choice when a request for the same is received. The mobile number transfer to a new network will be done in four days.
While, globally, there are two models of porting-donor-led and recipiend-led – India has opted for the subscriber- friendly recipient-led porting procedure. In this process, the new service provider, called the recipient, will take the initiative to register the subscriber in its network.
The subscriber's mobile number and the recipient's network ID are paired and updated on a master centralised database. This is managed by the MNP service provider in India.
Currently, Syniverse Technologies and Telcordia have been mandated with the task.
