New Delhi: Mobile operators Airtel, Vodafone, Idea, RCom and others including state-run BSNL and MTNL have announced rolling out from today the full mobile number portability (MNP) that will allow customers to retain their numbers across the country.

Other private players such as Uninor, Sistema Shyam Teleservices and Videocon will also roll out the service to meet the July 3 deadline fixed by the government. The national MNP service will facilitate customers to carry their existing mobile number from one telecom circle to another across the country and choose the operator of their choice without changing their numbers.

In a statement, Airtel said its customers can enjoy special offers like processing requests to port within Airtel's network within 24 hours and free incoming on roaming until the portability request is processed. Vodafone said, "Customers looking for the convenience of retaining their existing number at the new location can avail the benefits of national MNP service."

"Vodafone has benefited from the intra-circle MNP that was rolled out in 2011 and we look forward to a similar response this time," Vodafone India Chief Commercial Officer Vivek Mathur said. Idea Cellular said it has enabled its network to roll out the DoT mandated national MNP services for mobile users across the country.

"Idea has been the MNP leader with over 14 million net gain of customers so far, through intra circle MNP services. The company is now ready to enable national MNP by allowing its own users to retain their numbers even if they move out of a circle," Idea said.
