Thousands of Verizon customers reported complete loss of cellular service, with devices showing 'SOS' mode instead of signal bars. The carrier acknowledged the issue affecting wireless voice and data services.
Thousands of Verizon customers across the United States reported a complete loss of cellular service on Thursday, with devices displaying "SOS" mode instead of the usual signal bars. The outage appears to be widespread, affecting both voice calls and mobile data services.
Verizon confirmed the disruption, stating it is "aware of an issue impacting wireless voice and data services for some customers." The company has not yet provided details about the scope of the outage, affected regions, or estimated time for resolution.
What's Happening
Users began reporting issues early Thursday, with complaints flooding social media platforms and outage tracking websites. The "SOS" indicator on smartphones typically means the device can only make emergency calls, confirming a complete loss of network connectivity.
This marks Verizon's first major network disruption since October 2024, when a previous outage affected customers nationwide. The timing is particularly problematic given the carrier's recent marketing emphasizing network reliability.
Technical Context
Network outages of this scale typically stem from several potential causes:
- Core network failures: Issues with switching centers that route calls and data
- Backhaul problems: Failures in the fiber optic connections linking cell towers to the core network
- Software updates: Botched network configuration changes or firmware updates
- Hardware failures: Equipment malfunction at critical infrastructure points
- Power issues: Electrical failures at data centers or cell tower sites
The "SOS" mode suggests devices are unable to authenticate with Verizon's network entirely, rather than experiencing degraded service quality.
Customer Impact
Beyond the obvious inconvenience of losing phone service, the outage creates several practical problems:
- Emergency services access may be limited if users are in areas without Wi-Fi calling
- Mobile payment systems requiring cellular data are inoperable
- GPS navigation relying on cellular data fails
- Business communications are disrupted for mobile-first professionals
- Two-factor authentication codes sent via SMS cannot be received
What Comes Next
Verizon has not provided a timeline for restoration. Historically, carrier outages are resolved within a few hours once engineers identify and isolate the root cause. However, complex core network issues can take longer to fix without causing further disruption.
Customers experiencing the outage should:
- Enable Wi-Fi calling if available on their device and connected to a Wi-Fi network
- Avoid repeatedly restarting their devices, which can create additional signaling load on the network
- Monitor Verizon's official communication channels for updates
- Use alternative communication methods (Wi-Fi messaging apps, landlines) for urgent matters
The company will likely face scrutiny from regulators and customers, particularly given the timing so soon after their last major network failure. The Federal Communications Commission requires carriers to report significant outages, and Verizon may need to provide a detailed root cause analysis.
We'll update this article as Verizon provides more information about the cause and resolution of the outage.
