The carrier says the outage is over and has apologized to customers. Here’s the latest on the issue — with no clear cause yet.

Some Verizon customers went without cell service for over seven hours on Jan. 14. Here's what we know about the cause of the outage.

Verizon has finally confirmed what caused yesterday's nationwide outage. The company shared a statement with Mashable, confirming the outage stemmed from a software issue. Verizon specified the outage was not caused by a cyberattack.

In short, when you see SOS on your phone, it means you're not connected to a cellular network. "If you see SOS or 'SOS only' in the status bar, your device isn't connected to your cellular network, but you can still make emergency calls through other carrier networks," reads an Apple support page on the feature.

Verizon said it would "work through the night until service is restored" and said it would provide "account credits" for any customer who lost service.

Verizon’s outage yesterday was bad, but it proved the company knows one thing: When things go wrong, humans want to speak to humans.

Verizon says a software problem caused the glitch and they are conducting a postmortem, but experts say outages are "a fact of life" these days.

You can also go to the Verizon website to check the company's network status; however, this page appears to be experiencing intermittent problems. Mashable reporters were unable to access an updated map at Verizon's website, and instead received the same statement Verizon posted on X previously.

Verizon is issuing accounts credits to customers affected by yesterday's major outage. You might not be thrilled by the number, though.

While Downdetector did receive a spike in user error reports for T-Mobile and AT&T, at this time, Verizon seems to be the only major mobile carrier suffering an outage. In a statement on X, T-Mobile said that its network was functioning normally at this time.
