AT&T will start automatically blocking fraud calls and issuing suspected spam call alerts for new phone customers at no extra cost. “You’ll have to opt out if you don’t want the company to screen calls this way,” reports Engadget. “Existing customers, meanwhile, will see the feature automatically reach their accounts in the ‘coming months.'” From the report: If you like the capabilities, you can turn it on right now either by downloading the AT&T Call Protect app or enabling it through your myAT&T account settings. Although AT&T isn’t charging extra, the FCC rules don’t prevent it or others from using the auto-blocking as an opportunity to raise subscription rates. It may take a while to learn whether or not there are any pitfalls to what otherwise seems like a promising upgrade.
