T-Mobile is actively working to resolve a nationwide service outage that has affected users in New York City, New Jersey, North Dakota, and Berkeley, California, according to a Reddit thread with more than 6,000 comments. The disruption also impacts customers of MVNOs that rely on T-Mobile’s network, such as a Verge staffer using Google Fi. The outage, first reported on July 27, 2026, has left many customers without mobile service for several hours. T-Mobile declined to specify the cause of the outage, stating only that it is pursuing remediation. Analysts note that large-scale network failures can disrupt business operations and consumer confidence. The company has not provided a timeline for full service restoration, and the investigation into the incident remains ongoing.
