T-Mobile is down. Social media users are not taking it well.

In case you haven't heard, T-Mobile's mobile network appeared to go down for a lot of users on Monday afternoon.

Users in the United States reported a widespread outage, with mobile service in particular being disrupted, and some users reported they were stuck in "SOS mode," which can happen if service is interrupted. As usual, customers took to social media apps like X and Reddit to vent their frustrations, sometimes directly at T-Mobile itself.

On X, one user reported being stranded and unable to order a Lyft home (though, apparently, still able to post to X), while another said they were seeing a long line at their local T-Mobile store. Over on Reddit, a post about the outage has already collected more than 5,500 comments, with users trading rumors about the possible cause and potential fixes.

As a reminder: The person running a brand's social media help line typically can't fix the outage.

As of this writing, "T-Mobile" was trending on X, and search terms such as "Is t mobile down" and "t mobile outage" were trending on Google Search.

Mashable reached out to T-Mobile with questions about the outage, which the brand still hasn't acknowledged. We'll update this story if we receive more information.
