Try the app on mobile data instead of Wi-Fi, then restart the router. If reports start arriving from other people, this page flips to an outage within minutes.

How can I report a problem with T-Mobile?
Use the report panel on this page and pick what's not working — it takes one tap and no account. Reports are anonymous, and they feed the live signal on this page immediately.
How does down.now know if T-Mobile is down?
Down.Now watches two crowd signals for T-Mobile — anonymous reports submitted here, and public social-media posts about it — and compares the live volume against what's normal for that hour of the day. A sustained spike above that baseline opens an incident, which is usually visible before an official confirmation. We measure what users report, not T-Mobile's servers directly.
