California Challenges AT&T Copper Line Shutdown
California regulators (CPUC) filed with the FCC on June 15, 2026, accusing AT&T of providing false information in petitions to discontinue legacy copper-based landline service affecting roughly 199,000 California customers. AT&T submitted FCC applications in May 2026 to retire portions of its copper wireline network and replace service with an LTE-based "Advanced Phone" VoIP offering; AT&T also sued California in federal court seeking relief from Carrier of Last Resort obligations it says cost about $1 billion annually. The CPUC argues state rules do not block copper retirement and contends AT&T’s proposed wireless replacement fails the FCC’s Adequate Replacement Test because coverage maps emphasize outdoor conditions and do not guarantee reliable indoor service. The FCC issued a 2026 order streamlining discontinuance and contemplating preemption; California asked the FCC to reject or slow AT&T’s applications. The decision could shape how legacy copper networks are phased out nationwide.
A state regulatory filing against AT&T and an FCC policy direction on copper retirement could influence telecom infrastructure transitions and state-federal preemption precedents, but the story has limited direct impact on AdTech/MarTech operations.

AT&T to Phase Out Copper Phone Lines in California 2027
AT&T announced a $19 billion commitment to upgrade telecommunications infrastructure across California from 2026 through 2030, prioritizing expanded fiber-optic deployment and fixed wireless (5G) while retiring legacy copper phone lines. The company said it will begin discontinuing copper-based phone service in parts of California on or after June 1, 2027, using a phased approach over about one year and ensuring customers keep access to phone and 911 services. AT&T plans to extend fiber to more than 4 million additional locations (bringing total California fiber coverage to over 9 million) and add roughly 1,200 cell sites by 2030. Support measures include temporary free AT&T Phone – Advanced service for affected home phone users, hiring hundreds of technicians, community programs, and estimated energy savings by 2030. Correction: AT&T clarified that the current shutdown applies to copper phone service, not DSL.
FCC Plans Crackdown on Robocalls, Improve Broadband Data
The Federal Communications Commission published a tentative agenda for its May 20, 2026 Open Commission Meeting, outlining proposals to strengthen robocall protections, streamline broadband data collection, modernize disaster reporting, and explore High-Cost Program changes to support rural next‑generation services. The FCC, led by Chairman Brendan Carr, will consider a Further Notice of Proposed Rulemaking to tighten know-your-upstream-provider requirements under the STIR/SHAKEN framework. The agenda also includes a Report and Order and Further Notice on reforming the Broadband Data Collection process (audits, verification, and challenge mechanisms), a Third Report and Order to update the Disaster Information Reporting System, and a Notice of Proposed Rulemaking to solicit input on High‑Cost Program modernization. Drafts and summaries will be posted in advance and the meeting will be livestreamed from FCC headquarters on May 20.
FCC Grants AT&T One-Year Waiver on Foreign Router Rules
The Federal Communications Commission granted AT&T a one-year waiver allowing limited hardware modifications to previously certified foreign-made Wi‑Fi routers to address component shortages. The waiver permits substitutions such as changing substrate materials in chipsets and swapping memory modules so long as modifications do not improve performance, alter core functionality, or change the device marketing identity. The relief, effective until mid-2027, aims to prevent production interruptions and shortages of customer premises equipment (CPE) while preserving the FCC’s broader foreign-equipment security objectives; already-approved equipment may continue to receive software updates through at least early 2029. The decision addresses supply-chain constraints amid rising AI-driven demand for memory and could prompt other carriers to seek similar accommodations.
