• Users in Green Bay and across northeast Wisconsin say calls aren’t connecting; some can still text or use mobile data.
• WBAY’s news staff, who use Cellcom, experienced failures placing and receiving calls and have contacted Cellcom for comment.

What we know

DownDetector began showing a surge of reports after midnight indicating a possible Cellcom outage across northeast Wisconsin, including Green Bay. The pattern suggests a regional service disruption rather than isolated account problems.

Action 2 News staff, who use Cellcom for newsroom phones, confirmed they were unable to make or receive calls early Tuesday morning. Some customers report they can still send texts or use internet data; others cannot.

WBAY has reached out to Cellcom for details on root cause and estimated restoration time and will update this story when the carrier responds.

Where reports are concentrated

User-submitted reports on DownDetector and social posts indicate the most activity is centered in and around Green Bay and other parts of northeast Wisconsin. That concentration points to a regional network issue affecting voice services.

Outage trackers like DownDetector aggregate user reports and are a useful early indicator, but they do not confirm the technical cause. Official confirmation and outage maps from Cellcom provide the carrier’s view of scope and progress.

Immediate steps for affected users

If you can’t place or receive calls, first try toggling airplane mode or restarting your phone to force a network reconnection. Enabling Wi‑Fi calling (if available and configured) can restore voice service through a local internet connection.

Customers with urgent needs should attempt to connect via Wi‑Fi, use messaging apps over data, or make calls from a different carrier if possible. Keep emergency lines (911) in mind — if cellular and Wi‑Fi calling are both unavailable, use a landline if available.

How to monitor status

Check DownDetector for user reports and Cellcom’s official status page or social accounts for carrier updates. Local news outlets such as WBAY will publish updates as the carrier provides information.

We will continue monitoring the situation and update this article with confirmation from Cellcom and any restoration timeline. For now, expect intermittent voice service in affected parts of northeast Wisconsin and follow Cellcom’s official channels for the latest.
