A number of Americans are dealing with cellular outages on AT&T, Cricket Wireless, Verizon, T-Mobile and other service providers, according to data from Downdetector.

AT&T had more than 64,000 outages this morning, in locations including Houston, Atlanta and Chicago. The outages began at approximately 3:30 a.m. ET. The carrier has more than 240 million subscribers, the country’s largest.

�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.

Cricket Wireless had more than 13,000, the outage tracking website said Thursday. Verizon had more than 4,000 outages and T-Mobile had more than 1,900 outages. Boost Mobile had about 700 outages.

�Verizon�s network is operating normally. Some customers experienced issues this morning when calling or texting with customers served by another carrier. We are continuing to monitor the situation,� Verizon said.

T-Mobile said that it did not experience an outage.

�Our network is operating normally. Down Detector is likely reflecting challenges our customers were having attempting to connect to users on other networks,� T-Mobile said.

So far, no reason has been given for the outages.
