AT&T and T-Mobile team up in a first step toward identifying robocalls across networks

August 14, 2019

As the Federal Communications Commission wages war on robocalls, phone carriers are working together to ensure their customers are protected from scams.

AT&T and T-Mobile announced today calls across both networks would be verified, a step toward meeting the industry-wide SHAKEN/STIR standard.

SHAKEN/STIR verifies the authenticity of a call and alerts you if it is suspected as a spoof or scam. The call is verified at the network level and a symbol such as a check mark will appear to let you know if the call is not spoofed. With AT&T and T-Mobile, you will see “Call Verified” on your screen when you get a call.
