Verizon, AT&T, and T-Mobile are all experiencing significant service disruptions. Verizon is facing a nationwide outage, causing many customers to lose cellular connectivity and see an 'SOS' message on their phones. This is also preventing calls and texts from AT&T and T-Mobile users from reaching Verizon customers. Verizon's Fios home internet service is also reportedly offline for many users.

T-Mobile is reporting its own service disruptions, which could point to a failure in shared infrastructure used by major carriers. While AT&T and T-Mobile initially appeared to have issues, those reports were likely from people trying to contact Verizon customers. Both AT&T and T-Mobile have confirmed their networks are operating normally, with the primary problem stemming from Verizon's outage.

Verizon acknowledged the problem on Twitter, stating its engineers are working to resolve the issue impacting wireless voice and data services. The cause of the disruption remains unclear as of now. For those affected, the recommendation is to use data-based services like iMessage or Signal to stay connected. We will continue to monitor the situation as more information becomes available.
