SIM-Swapping Attacks Are Now Protected by T-Mobile

SIM swapping attacks, which can result in customers losing access to their phone service and having their personal information stolen, have been an issue for mobile carriers for years. Thankfully, networks like T-Mobile are taking the issue more seriously. The assaults often entail someone impersonating you and calling your carrier's customer service to request a new SIM card. If they are successful, they will be able to get a new SIM card and activate it on a device that they own, robbing connectivity and your device's number. To access a person's internet accounts, SIM swap attacks are frequently combined with SMS-based two-factor authentication and passwords obtained from earlier data breaches. Various tactics have been explored by each cell network to prevent SIM swappings, such as greater training for customer care agents and updated verification procedures, yet it still occurs infrequently. Customers of T-Mobile now have access to a new account setting called SIM protection, which prevents any changes to their SIM cards (such activation on a different smartphone) until the block is lifted. The option isn't turned on by default, probably to prevent problems for those who switch SIM cards among their own devices. The "Privacy and notifications" section of your account settings is where you can locate it if you use T-Mobile; the source link below offers more specific instructions. You can switch it on for each phone line separately or enable it for all phone lines associated with an account. It's wonderful to see more security choices for phone lines, especially since many carriers struggle to integrate features like app-based two-factor verification, which are typical of other sorts of online accounts. We can only hope that all networks will adopt a similar functionality.
