Mobile Number Portability (MNP) is the ability for users to switch to a new mobile service provider, while retaining their existing mobile number.
The main benefit of MNP is freedom of choice and the competition that it generates. Now you are free to choose a new mobile service provider without having to change to a new number. This means you can avoid the inconvenience of having to notify friends and associates that you have changed your number.
