What happened

Early Tuesday morning on Dec. 9, multiple reports began appearing on DownDetector indicating possible service problems for Cellcom customers.

Local newsroom staff at WBAY’s Action 2 News — which uses Cellcom — said team members were unable to make or receive calls during the incident.

Where reports are coming from

DownDetector’s outage map and user submissions point to disruptions across northeast Wisconsin. Reports were concentrated in and around Green Bay and nearby communities.

DownDetector aggregates real-time user reports, making it a useful first signal when larger carriers experience localized issues.

How customers are affected

Impacts vary by user: some people could still send text messages and use mobile internet, while others lost those services entirely.

Voice calls appeared to be the most commonly reported problem during the early hours, according to local reporting and user posts on outage trackers.

Cellcom response and updates

WBAY reached out to Cellcom for details about the cause and expected time to resolution and said it will update the story when the carrier responds.

At the time of reporting, Cellcom had not published a public status update on the outage. Customers should check the carrier’s official status page or social channels for confirmations.

What you can do now

If you’re affected, try these quick steps before contacting support. Many of these resolve simple service or network registration issues.

Quick troubleshooting

  • Restart your phone to force a fresh network registration.
  • Toggle Airplane Mode on for 10 seconds, then turn it off.
  • Enable Wi‑Fi calling in your phone settings if available and connect to a reliable Wi‑Fi network.
  • Check DownDetector and Cellcom’s official status or social accounts for live updates.
  • Contact Cellcom customer support if the problem persists.

Why this matters

Even short outages can disrupt emergency calls, business communications and daily routines. Monitoring aggregator sites like DownDetector alongside official carrier channels helps customers confirm whether issues are widespread.

WBAY will update this article as Cellcom provides more information and when service is restored.
