Shortly after the issues were reported on Downdetector, searches surged on Google for SOS mode , which can appear on devices when service is disrupted. SOS mode means your phone should still be able to make emergency calls if needed.
On X, dozens of users complained of an outage, with some users specifically complaining about SOS mode.
So far, T-Mobile hasn't acknowledged any problems.
