Is T‑Mobile Down? What To Know About The Nationwide Outage And 'SOS' Alerts

If you have a cellphone plan with T‑Mobile, you may have seen an "SOS" indicator on your phone signaling disrupted service. This was not a problem with individual handsets — it reflected a widespread outage at the carrier on Monday that affected many customers across the country.

What Happened

Reports of lost signal peaked at about 5 p.m. ET, when DownDetector logged more than 60,000 reports of outages. Although reports fell later in the evening, there were still more than 17,000 incidents logged at the time this article was published.

The disruption reportedly affected T‑Mobile customers nationwide. Mobile virtual network operators (MVNOs) that operate on T‑Mobile's network — including Mint Mobile and Boost Mobile — also reported problems, according to StatusGator. At the time of publication, T‑Mobile had not issued a public comment about the outage.

What You Can Do Now

• Check status pages: Visit DownDetector, StatusGator or T‑Mobile's official support pages and social accounts for updates.
• Restart your device: Rebooting can restore service after network issues are resolved.
• Enable Wi‑Fi calling: If available, switch to Wi‑Fi calling to make and receive calls while cellular service is disrupted.
• Use alternative apps: Messaging and calling apps that use Wi‑Fi (e.g., WhatsApp, FaceTime, Signal) can keep you connected.
• Contact support: If you experience ongoing problems after the outage is cleared, contact your carrier for account-specific help.
