Functionality of MNP

Mobile Number Portability (MNP) is the ability of a mobile subscriber to retain his/her number when changing network operators within a country. Mobile Number portability is a key aspect of deregulation to ensure competition in the telecom industry.

MNP is not a subscriber service. It is a network feature that allows the subscriber to keep a unique mobile phone number. The absence of MNP may give the existing cellular mobile operators a significant competitive advantage over new entrants in the market. MNP is the important mechanism to enhance fair competition among different operators.

With number portability, a subscriber can decide to take his or her number and request service from another provider. The network provider that originally owned this number as part of a numbering block assignment is referred to as the donor network. The network provider that the subscriber approaches to host its number is called the recipient network. Note that the subscriber might want to switch service provider again after some time. Thus, the recipient network can change over time, as often as a subscriber changes the provider; however, the donor network is always considered to be the original network that owned the address block from which this subscriber number came.
