T-Mobile's network appears to be suffering from a Hump Day Hiccup.

Many T-Mobile customers are reporting that they're unable to send or receive calls this afternoon. Lots of reports of failed calls are popping up on Down Detector and Twitter, and some customers say they're having issues with text and data, too, but those problems don't seem quite as widespread.

While T-Mobile hasn't made an official statement on the outage, the T-Mobile Help account on Twitter says that the carrier is aware of the network problems that customers are suffering from. There's no word yet on when the issue might be resolved, but T-Mobile Help says that T-Mo engineers "are all over it."

Are you having any problems your service today, T-Mobile customers?

UPDATE: T-Mobile CEO John Legere has confirmed that "some customers are experiencing intermittent call issues", but he says that the problem is being worked on and that there are "some signs of recovery."

Some customers are experiencing intermittent call issues on our network. Thanks for your patience... @NevilleRay and team are working to resolve the problem ASAP and have already started to see signs of recovery.
