The CAI Community"nationwide issue" that affected communication between AT&T customers and other non-AT&T customers was resolved Tuesday, the company said.

AT&T customers reported a loss or disruption to services Tuesday afternoon, with those serviced by the carrier writing on social media that they could not make calls or send texts. The total number of customers impacted by the issue was not immediately available.

The company said they were "working as quickly as possible to diagnose and resolve the issue," reporting a couple hours later that "the interoperability issue between carriers had been resolved."

"We collaborated with the other carrier to find a solution and appreciate our customers patience during this period," an AT&T spokesperson shared with USA TODAY.

AT&T customers were still able to make calls between other AT&T customers and calls to emergency services.

The Federal Communications Commission chimed in as the situation developed, writing on X that the agency would be investigating why "consumers in multiple states are unable to make wireless calls."

Verizon customers also report service loss

AT&T wasn't the only telecommunications company dealing with network issues. Verizon customers began to report disruption and loss of service around the same time.

A Verizon spokesperson said its network was operating normally, but that customers "in the Northeast and Midwest, are experiencing issues when calling or texting with customers served by another carrier." And that they would continue to monitor the situation accordingly.

Verizon could not be reached for comment Tuesday night.

AT&T, Verizon customers were over it, react accordingly

AT&T customers were left in the dark earlier this year

Millions of AT&T customers experienced issues with their service earlier this year, when the company reported that a "technical error" was the reason why customers were unable to make calls or send messages for most of Feb. 22, USA TODAY reported.

The company formally addressed the outage days later, stating that "the application and execution of an incorrect process" was the reason for the malfunction. And that they were not victims of a "cyberattack."

A $5 rebate was offered to customers who were impacted by the outage.
