New Delhi, Jan 31 (IANS): Keeping in view upsurge in mobile number portability (MNP) requests, the Telecom Regulatory Authority of India (TRAI) has decided to slash its rate to Rs 4 per successful porting from Rs 19 earlier.

The TRAI arrived at the decision after taking into consideration the comments received from the industry stakeholders.

A statement issued by the TRAI said it would come into effect from the date of official Gazette notification.

Under the MNP regime, a subscriber can retain the existing mobile telephone number while switching from one service provider to another or from one technology to another technology of the same service provider. It allows subscribers to retain their mobile number not only within the same Licensed Service Area (LSA) but also pan India in any LSA.

After observing a significant decline in the per port transaction cost, the sectoral regulator decided to slash the price.

"After reviewing the financial results of both the MNP Service Providers and the upsurge in the volume of porting requests in the past two years, the Authority opined that the present charge of Rs 19 is quite high as compared to cost and volumes of transaction involved," the statement said.
