T-Mobile to pay nearly $20 million after outage leads to thousands of 911 calls failing

Some 23,000 emergency calls failed during the 12-hour outage last June.

T-Mobile will pay some $19.5 million as part of a settlement with the Federal Communications Commission after a 12-hour outage in June of last year resulted in the failure of tens of thousands of emergency 911 calls.

On June 15, 2020, a 12-hour and 13-minute outage took place that led to congestion across T-Mobile's 4G, 3G and 2G networks, according to the FCC, and resulted in the "complete failure" of more than 23,000 911 calls. The outage also resulted in tens of thousands of 911 calls without location or call back information made available.

"We understand how critical reliable connectivity is to ensure public safety and we take that responsibility very seriously," T-Mobile told ABC News in a statement Wednesday. "We have built resiliency into our emergency systems to ensure that our 911 elements are available when they're needed."

"This was a short-term isolated outage and we immediately took steps to further enhance our network to prevent this type of event from happening in the future," the company added. "Now we are moving on from the FCC's investigation and continuing our focus on our ongoing network build."
