AT&T is experiencing an outage because calls are not going through to other providers

AT&T users were once again experiencing issues with their wireless service, with the carrier confirming Tuesday afternoon that there were issues connecting calls to users on other networks.

“There is a nationwide issue impacting customers’ ability to complete calls between carriers,” an AT&T spokesperson told CNET in a statement. “Carriers are working as quickly as possible to diagnose and resolve the issue.”

The spokesperson added that “national 9-1-1 services are operating normally at this time and our customers are not affected. We are working to correct a wireless impact notification that was incorrectly sent to 9-1-1- call centers has been dispatched.”

CNET confirmed that calls to users on other networks in New York from the AT&T service were not going through, although calls to other people who were also on AT&T worked fine. Calls made through apps or services, such as FaceTime or WhatsApp calls, worked fine over mobile data such as 5G. AT&T’s data services did not appear to experience any problems.

In a statement, Verizon said its network is functioning well. “We have a number of customers experiencing difficulty calling or texting customers of another carrier. We are monitoring the situation.”

AT&T’s outage is the latest major issue the carrier has faced in recent months. In February, the service was hit by a nationwide outage, disrupting service and cutting off mobile connectivity for hours. It blamed software for that problem and gave users $5 account credits as an apology.

It’s unclear what caused Tuesday’s problem, when it might be resolved and whether AT&T will provide credit for this latest problem.
