“We are aware of an issue impacting service for some customers,” Verizon said in a statement. “Our engineers are engaged and we are working quickly to identify and solve the issue.”

AT&T, meanwhile, said another carrier experiencing a network issue was preventing its customers from calling their customers.

“We are not experiencing a nationwide outage,” AT&T said on X. ” Our national network is operating normally. Down Detector is likely reflecting challenges our customers are having attempting to connect to users on another network.”
