Number portability allows customers to keep their phone number when switching service providers. When a customer decides to switch providers, they simply request to port their existing number to the new provider. The new provider then contacts the old provider to initiate the transfer process. Once the transfer is complete, the customer's phone number is now associated with the new provider's service. This process helps to promote competition among service providers and gives customers more flexibility and choice. **
