T-Mobile Fiber Outages Continue in Select Areas
The outages are concentrated in areas served by fiber previously owned by Lumos.
June 1, 2026 – T-Mobile Fiber customers across several southeastern states continued reporting internet outages Monday after a network disruption stretched into its fifth day.
The outage first surfaced early Thursday and primarily affected customers in North Carolina, South Carolina, Georgia, and Virginia. While T-Mobile said service had been restored for many users, customers continued reporting connectivity problems through the weekend and into Monday.
The disruption appears to have been limited largely to T-Mobile Fiber, the company’s home broadband service built in part through its acquisition of regional fiber provider Lumos, rather than affecting T-Mobile’s nationwide wireless network.
Customers in cities including High Point, Burlington, Lexington, Thomasville and Wilmington, North Carolina, reported prolonged outages.
“We know some T-Fiber customers are still experiencing service disruptions, and we apologize for the inconvenience,” T-Mobile Help said in a statement posted Saturday on X.
Frustrated customers have since been reporting outages on social media and outage-tracking websites as the outage continues to affect many homes in North Carolina.
“Everyone who has talked to T-Mobile is saying that ‘there is no outage in GSO [Greensboro].’ It's an absolute lie,” one customer wrote in a post to Down Detector.
The outage comes as T-Mobile expands its presence in the fiber broadband market, a sector long dominated by cable and traditional telecommunications providers. The company completed its acquisition of Lumos about a year ago as part of a strategy to complement its rapidly growing fixed wireless broadband business.
T-Mobile had previously planned to expand Lumos’ network footprint from approximately 450,000 fiber passes today to 3.5 million homes by the end of 2028. The company has also committed an additional $500 million investment into Lumos between 2027 and 2028 as it works to increase fiber availability across its service territory.
The carrier is also pursuing a separate fiber joint venture that could add another 6.5 million passings by the end of the decade.
“With the official launch of T-Mobile Fiber, we’re delivering on our promise to bring better broadband to more people,” Allan Samson, T-Mobile Chief Broadband Officer, said when the service was formally launched last year.
