AT&T Prepaid Port Out Process
The port-out process for AT&T Prepaid allows customers to keep their existing phone number when switching to another carrier. It involves verifying the customer’s account information and ensuring the account is active before the transfer can take place. This process is designed to protect the customer’s privacy and prevent unauthorized transfers. Once approved by both carriers, the number transfer is usually completed quickly and seamlessly, minimizing any disruption in service.
