The outage appears to be centered in Utah and affecting T-Mobile-based MVNOs such as Google Fi Wireless and Mint Mobile.
If you're a T-Mobile customer and have found that you can't connect to the network, then you are not alone. The carrier appears to be dealing with a network outage in certain parts of the U.S., with Downdetector seeing a spike in outage reports.
The reports seem to have started around 2 p.m. EST, and it seems the outage is mostly concentrated throughout the state of Utah, although it may be affecting other areas as well. Local news in Salt Lake City has reported that users across the state appear to be affected by the outage.
The outage appears to be affecting other carriers that rely on T-Mobile's network. That includes Metro by T-Mobile, Mint Mobile, and Google Fi-Wireless.
So far, T-Mobile has not publicly commented on the outage on its social media accounts but apparently told one news outlet that a "major event" was causing the outage (via Tom's Guide). Android Central has reached out for a comment to confirm the status of the outage and affected areas, and we will update this article when we hear back.
