Cellcom outage hits Northeast Wisconsin — what we know now and what it means for customers

A new cellcom outage has hit parts of northeast Wisconsin early Tuesday morning, disrupting mobile voice service for many residents and businesses — again. Reports began pouring in shortly after midnight, with users saying they could not make or receive calls. Some could still send texts or use mobile data, while others lost nearly all mobile service. At this hour, the provider has not published a full public statement explaining the outage or offering a concrete timeline for resolution.


🚨 What’s happened so far

  • Starting just past midnight, multiple users in northeast Wisconsin reported an inability to make or receive calls using their wireless phones. The outage appears to affect voice services first, with mixed reports about texting and data functionality.
  • Some users also described their phones showing “SOS mode,” meaning emergency calls and essential alert services could still function, but regular calls, texts, and mobile data either were unreliable or unavailable.
  • The outage seems scattered — while many customers in the Green Bay and Fox Cities region report issues, others say their service remains unaffected.
  • The carrier has not yet posted any official notice on its website or social media accounts addressing the outage.

Why this matters

For customers relying on their phone — to stay in touch with work, family, or emergency services — the outage is more than an annoyance. Some of the immediate consequences include:

  • Communication breakdown: Many people cannot call, text, or reliably use mobile data. That affects daily life, work calls, scheduling, and critical communication.
  • Emergency preparedness concerns: If basic mobile service is down, access to emergency contacts or quick help becomes more difficult — even if “SOS mode” can allow 911 calls, delays or inconsistent service are risky.
  • Business disruption: Local businesses, especially small operations, may struggle to reach customers, fulfill orders, or take appointments if their phones are down.
  • Trust erosion: Given prior incidents, repeated outages may make customers question the reliability of their carrier and seek alternatives.

Context: This isn’t the first time

This outage echoes a larger-scale disruption that the company experienced earlier this year. In mid-May 2025, the same wireless provider suffered a prolonged outage that lasted days for many customers. That event affected both voice and SMS — at one point leaving users unable to make calls or send texts for a full week or more.

At the time, the company confirmed the outage was caused by a cyber incident that targeted its voice and texting networks — but data services and emergency calling reportedly remained available.

Because of that disruption, the company later offered bill credits to affected customers, including a “Double the Downtime” credit for eligible accounts.

That 2025 outage drew scrutiny from regulators, including the national telecom oversight agency, which requested feedback from customers and public safety organizations about how the outage affected critical services like 911.

Given that background, today’s outage may deepen concerns among customers and watchers that the carrier remains vulnerable to service disruptions.


What customers can — and should — do now

If you’re currently facing issues, here are some practical steps:

  • Check alternative communications: If voice is down, use internet-based platforms such as messaging apps or email — provided mobile data or WiFi still works.
  • Test your mobile data and 911 capability: If you can, test whether emergency calls connect or whether a data-based VoIP or messaging service still functions.
  • Monitor for updates: The carrier may eventually post a service update explaining the outage’s scope, cause, and recovery timeline — but don’t rely solely on that. Local media and social media may give quicker clues about which areas are affected.
  • Be ready to switch providers: If outages become frequent or extended, it may be worth evaluating alternative carriers or backup communication options — especially if reliable connectivity is critical for work or safety.
  • Document impacts: If the outage affects your work, safety, or daily life significantly, consider documenting the disruption. That may help if the carrier offers credits or if regulators seek public input.

Why this outage matters beyond Wisconsin

While this incident is concentrated in northeast Wisconsin, the broader implications echo nationwide:

Telecommunications providers — especially regional carriers — underpin essential infrastructure. Their networks support not just casual calls, but emergency services, local businesses, logistics, healthcare communications, and more. Repeated outages, especially caused by cyber incidents, highlight persistent vulnerabilities in a system that many Americans rely on daily.

That raises questions about network resilience, disaster recovery procedures, transparency, and regulatory oversight. As telecom customers nationwide watch and wait, what happens here could influence expectations — and policy — for carriers everywhere.


What to watch next

  • Official statement from provider: A formal update explaining the cause, scope, and restoration timeline will be crucial.
  • Regulatory scrutiny or public feedback: Given past events, oversight agencies may open inquiries — or encourage affected customers to report their experiences.
  • Customer reaction and possible fallout: Extended outages may drive defections to other carriers — or demand for stronger reliability guarantees.
  • Larger cybersecurity concerns: If a cyber-incident caused the disruption, this could be another sign that telecom networks remain high-value targets for hackers and need better baseline protections.
