A major problem with the Cellcom network has caused many people in northeastern Wisconsin to lose their phone call and text services since the night of May 14, 2025. This has made it hard for people to talk, businesses to work, and schools to communicate.

More Than 300,000 People Affected

The outage is happening in several counties, including Brown, Door and Marinette. While internet data and emergency 911 calls still work, many people can’t make regular calls or send text messages. Many are now using apps like WhatsApp and iMessage to stay in touch.

Cellcom Is Working on Fixing It

Cellcom said they know about the problem and are trying to fix it as soon as possible. However, they have not said when everything will be back to normal. They also warned people to be careful of scammers during this time. Cellcom will never ask for personal details like passwords or bank info over the phone or text.

Scammers Are Trying to Trick People

Because of the outage, scammers are sending fake messages pretending to be from Cellcom. They claim that accounts are blocked or need urgent checks. Police and the Better Business Bureau warn people not to answer suspicious messages and to use only official Cellcom websites or apps for updates.

Schools and Businesses Are Struggling

Schools like Ashwaubenon are asking parents to use email instead of phone calls. Businesses, especially busy ones like Pulaski Warehouse, say it is hard to contact customers. Delivery drivers for DoorDash and Instacart also have trouble communicating with people.

Public Services Are Also Affected

Although emergency calls still work, many government phone lines for other services are down. Students at Northeast Wisconsin Technical College can’t complete security steps needed to access their online classes, causing more problems.

People Are Upset

Many Cellcom users have shared their frustration online because there is little information about when the problem will end. Some think the issue might be a cyberattack, but Cellcom says their system was not hacked. Customers are worried about trust and want better communication.

Possible Cause: Third-Party Service Issue

Experts think the problem might be connected to Twilio, a company that helps many phone providers with text services. This shows how companies rely on outside services, which can sometimes cause big problems.

How to Stay Safe Now

  • Don’t click on strange links or reply to unknown texts.
  • Use two-step verification on your Cellcom account.
  • Check only official Cellcom websites or apps for news.
  • Report any scams to the Federal Trade Commission website.
  • Keep your phone and apps updated.

People Want Answers

Many customers want the government to check this outage closely and make sure Cellcom fixes these issues faster. The problem also raises questions about how strong and reliable phone services really are in the area.
