What is the purpose of Number Portability in telecommunication?

1. To enhance data security during phone calls

2. To track the location of phone users accurately

3. To improve call routing efficiency

4. To allow users to retain their phone numbers when changing carriers

The correct answer is: To allow users to retain their phone numbers when changing carriers

Number Portability in telecommunication refers to the ability of a customer to keep their phone number when switching to a new service provider. This is beneficial for customers as they do not have to inform all their contacts of a new number, and it encourages healthy competition among service providers. Options A, B, and C are incorrect as they do not accurately describe the purpose of Number Portability. Number Portability does not have a direct impact on data security during phone calls, tracking the location of phone users, or improving call routing efficiency.
