AT&T says nationwide issue affecting ability of customers to make calls

AT&T on Tuesday said the telecommunications company and other wireless carriers are working to fix an issue preventing customers from completing calls placed to non-AT&T customers across the U.S.

"There is a nationwide issue that is affecting the ability of customers to complete calls between carriers. The carriers are working as quickly as possible to diagnose and resolve the issue," the carrier stated in a post on X.

Calls between AT&T customers were not impacted, the telecom said.
