AT&T, Verizon and T-Mobile customers hit by widespread cellular outages in US

AT&T’s network suffered a widespread outages across the country Thursday morning with cellular service and internet down, according to the tracking site Downdetector.

Some Verizon and T-Mobile customers also reported outages, though theirs appeared to be less widespread than AT&T.

Over 32,000 AT&T outages were reported by customers at about 4 a.m. ET Thursday. Reports dipped then spiked again to more than 50,000 around 7 a.m., with most issues reported in Houston, Chicago, Dallas Los Angeles, and Atlanta, according to the site.

That number surged to more than 64,000 just before 8 a.m. ET.

A little over 1,100 T-mobile outages and about 3,000 Verizon outages were reported as of 7 a.m. Thursday.

It’s not clear what triggered the service disruption.

NBC News has reached out to AT&T for comment on the issue. Though the company has not put out a statement, it has responded to customers on X.

Verizon said Thursday morning that the outages are not impacting their network directly, but are impacting their customers trying to reach another carrier experiencing the issue.

T-Mobile also said early Thursday that the network didn’t suffer an outage and is operating normally, and Downdetector numbers likely reflect customers attempting to reach users on other networks.

The outages pose a concern as some people may be unable to call 911 in the case of an emergency.

San Francisco’s Fire Department said on X that it was aware of an issue impacting AT&T wireless customers from making and receiving phone calls, including 911.

“The San Francisco 911 center is still operational,” the office said. “If you are an AT&T customer and cannot get through to 911, then please try calling from a landline. If that is not an option then please try to get ahold of a friend or family member who is a customer of a different carrier and ask them to call 911 on your behalf.”

Similarly, Virginia’s Prince William County police department and North Carolina’s Charlotte-Mecklenburg police department have issued warnings on X alerting the public about the outage while acknowledging some customers were briefly unable to contact 911.
