The disruptions affected calls, texts, and internet access on mobile phones, prompting concerns about contacting emergency services.
The FBI, DHS, and FCC are investigating the outages, with AT&T reporting no signs of a cybersecurity incident. While AT&T experienced the most significant outages, Verizon and T-Mobile also reported disruptions, albeit on a smaller scale.
