Customers of cellular services nationwide, including AT&T, T-Mobile and Verizon, have reported to Downdetector and social media that their phone service is down.
But AT&T is the only major service provider confirming an outage so far.
AT&T had more than 60,000 customers reporting outages this morning, in locations including Houston, Atlanta and Chicago, the Associated Press reported.
“Some of our customers are experiencing wireless service interruptions this morning. We are working urgently to restore service to them. We encourage the use of Wi-Fi calling until service is restored,” AT&T said in a statement.
