Pakistan has implemented Mobile number portability across all carriers. While at the same time DoT in India under pressure from the Cellphone companies has virtually shelved the plan which would have benefited hundreds of millions of subscribers across the country.
Number portability allows a customer to move from one mobile service to another within GSM, and also between GSM and CDMA, while retaining the same number. It gives flexibility to customers and keeps operators on their toes lest their service quality falls.
According to an IDC survey, over 30 per cent of mobile subscribers would change their operators if they had number portability.
