Beginning at around 3:30 a.m. ET on Feb. 22, many people began experiencing cell phone service outages across the U.S.. The outage left people unable to make phone calls or send and receive text messages without a Wi-Fi connection. AT&T is the only one of the three major cell carriers that is experiencing network disruptions. Both Verizon and T-Mobile report that their networks are operating normally. “Some of our customers are experiencing wireless service interruptions this morning,” an AT&T spokesperson told VERIFY shortly before noon ET. “Our network teams took immediate action and so far, three-quarters of our network has been restored. We are working as quickly as possible to restore service to remaining customers.” Verizon and T-Mobile, on the other hand, both told VERIFY that issues reported by customers are likely a result of attempting to call or text people who are on another network. “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,” a Verizon spokesperson said.
