(Reuters) -AT&T, Verizon and T-Mobile said on Tuesday that some customers were having problems with calls made to other wireless carriers, prompting the Federal Communications Commission to investigate.
The extent of the problem was not immediately clear.
AT&T said in a statement: “There is a nationwide issue that is impacting customers’ ability to complete calls between carriers. We are working closely with Verizon to determine the nature of the issue and what actions need to be taken.”
AT&T added that its network was “not experiencing a nationwide outage.”
Verizon said in a statement that its network was operating normally, but that some of its customers in the Northeast and Midwest were “experiencing issues calling or texting customers served by another carrier. We continue to monitor the situation.”
Tracking website Downdetector.com showed more than 2,300 outage reports as of 5:46 p.m. EDT, with the New York neighborhoods of Brooklyn, Chicago and Philadelphia among the most reported locations.
T-Mobile US said “there has been no outage. We are seeing increases in Down Detector with other providers, so this could likely be a challenge our customers are experiencing connecting with users on other networks.”
The FCC and New York Attorney General Letitia James said in February they were investigating the cause of an AT&T outage earlier that month, as well as the telecommunications company’s response. The outage lasted more than 10 hours and impacted more than 70,000 customers.
AT&T credited customers with a full day of service for the carrier outage.
