AT&T Sues California Over Costly Copper Landline Network Requirements
AT&T is pushing back against California rules that require the company to keep operating its aging copper wire phone network, even as most residents have moved on to wireless, fiber, or internet-based phone services.
The telecom giant has filed a lawsuit against the California Public Utilities Commission and the state attorney general, seeking relief from obligations tied to its traditional analog landline service. At the center of the dispute is a decades-old copper network that now serves only a small share of California customers but still requires major investment to maintain.
According to AT&T, just about 3 percent of residents in the state still rely on copper-based analog phone service. Despite that shrinking customer base, the company says it must spend up to $1 billion per year to keep the legacy network running. AT&T argues that this requirement is no longer practical in an era where fiber broadband and cellular networks provide faster, more reliable, and more efficient connectivity.
The company is also asking the Federal Communications Commission for permission to discontinue analog phone service in California areas where modern alternatives, such as wireless and fiber networks, already provide stronger coverage. AT&T says the goal is not to leave customers without service, but to move them away from outdated infrastructure and toward newer technologies.
As part of its argument, AT&T points to its ongoing investment in California’s broadband future. The carrier says it plans to spend $19 billion through 2030 to expand fiber access to 4 million additional homes and businesses across the state. That investment, AT&T claims, would better serve California consumers than continuing to pour money into an aging copper phone system with limited use.
The company is also highlighting the environmental and reliability benefits of retiring copper-based analog phone lines. AT&T estimates that moving away from the old network could save around 300 million kilowatt-hours of electricity annually by 2030. The company compares that energy savings to removing emissions equal to the use of 17 million gallons of gasoline.
Another issue is copper wire theft, which has become a recurring problem for telecom providers. AT&T says retiring the copper network could prevent around 2,000 outages each year caused by stolen copper lines. These outages can disrupt service and require expensive repairs, adding yet another reason the company wants to transition away from the older system.
The lawsuit marks a major moment in the broader shift from traditional landline phones to modern digital communications. For AT&T, the case is about cutting the high costs of maintaining outdated infrastructure. For regulators, the challenge is ensuring that customers who still depend on analog landlines are not left behind, particularly seniors, rural residents, and people in areas where wireless or fiber access may still be limited.
The outcome could shape how quickly legacy copper phone networks are phased out in California and potentially influence similar debates in other states. As telecom companies continue investing in fiber broadband and 5G coverage, the future of old-fashioned copper landline service appears increasingly uncertain.
