AT&T Sues California to Shed ‘Century-Old’ Copper Phone Network

The Battle Over Legacy Infrastructure
AT&T has filed a lawsuit against California officials, seeking a court order that would exempt the wireless carrier from the requirement to offer traditional copper-wire telephone service to new customers. The legal move marks a significant escalation in the company’s effort to decouple its business model from the aging infrastructure of the 20th century.
At the heart of the dispute is a century-old network of copper lines—often referred to as Plain Old Telephone Service (POTS)—that once served as the backbone of American communication. While the technology is now largely obsolete in the era of VoLTE and fiber optics, state regulations in California have required AT&T to keep the network operational and accessible to all residents, regardless of how many people actually use it.
In court filings, AT&T argues that the financial burden of maintaining this legacy system has become unsustainable. The company claims it is forced to spend roughly $1 billion annually just to keep the network running, despite the fact that only 3% of its customer base still relies on these traditional lines. For a company pivoting toward a future of 5G and high-speed broadband, the expense is viewed not as a service, but as a dead weight.
$19 Billion in Modernization
The lawsuit isn’t just about cutting costs; it’s about where those costs are redirected. AT&T has vowed to invest $19 billion into modernizing telecom services, shifting focus away from copper and toward fiber-to-the-home (FTTH) and enhanced wireless capabilities. By shedding the regulatory shackles of the old copper network, AT&T believes it can accelerate the rollout of high-speed internet to underserved regions of the state.
The tension here lies in the definition of “universal service.” California officials have historically maintained that telephone access is a critical utility, particularly for rural populations or low-income households who may not have the means or the infrastructure to support high-speed digital alternatives. By requiring AT&T to keep the copper lines open, the state aims to ensure no citizen is left without a basic lifeline.
AT&T, however, contends that maintaining a 100-year-old network is an inefficient way to achieve that goal. The company suggests that modern alternatives are more reliable and cost-effective, rendering the state’s insistence on copper not only outdated but counterproductive to the broader goal of digital equity.
A Growing Trend in Telecom Litigation
This legal clash is not an isolated incident. Across the U.S., major carriers have been pushing regulators to allow them to retire legacy systems. As the industry shifts toward an all-IP (Internet Protocol) environment, the physical maintenance of copper wires—which are prone to degradation, water damage, and physical wear—has become a logistical nightmare.
If AT&T succeeds in California, it could set a precedent for other states to follow, potentially triggering a wave of similar lawsuits and regulatory petitions. The outcome will likely depend on whether the court views the copper network as a redundant relic or as a necessary safeguard for public safety and accessibility.
For now, the $1 billion annual spend remains a point of contention. AT&T is essentially betting that the judiciary will agree that the 3% of users left on copper do not justify the massive overhead required to keep the lights on for a technology that the rest of the world has largely forgotten.
