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.
Major regional telecom infrastructure investment and planned retirement of legacy copper networks will affect connectivity, broadband capacity and services in California—relevant to media distribution and connectivity-dependent industries.

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.
AT&T Adds 646,000 Internet Customers in Q2 2026
AT&T reported strong second-quarter 2026 results driven by home internet growth, adding 367,000 fiber customers and 279,000 5G Home Internet (AT&T Internet Air) subscribers for a total of 646,000 net additions across consumer and business advanced connectivity services. Advanced connectivity revenue rose to $23.5 billion (up 5.1% YoY) with operating income of $7.3 billion and EBITDA of $12.0 billion. AT&T passed an additional 1 million fiber locations during the quarter, bringing its total fiber passings to 38.6 million and targeting more than 40 million by the end of 2026 and 60 million by 2030. The company also added 432,000 postpaid phone subscribers; consolidated revenue was $31.6 billion, adjusted EPS $0.65, and free cash flow $4.7 billion. The company reiterated full-year 2026 guidance and plans for accelerated share repurchases.
German Carriers Plan 2G Shutdown in 2028
O2 Telefónica announced in Munich that it will shut down the legacy 2G (GSM) mobile network in the second half of 2028 in Germany. Vodafone and Deutsche Telekom have made similar commitments for 2028; Vodafone plans to keep part of the 2G spectrum available for certain industrial IoT use cases until 2030. Operators say freeing 2G frequencies will allow reallocation to 4G and 5G, improving capacity and coverage for modern data-heavy use like streaming and mobile work. 3G has already been decommissioned (2021); Bundesnetzagentur figures cited show near-nationwide coverage for 2G (99.78% by at least one operator), 4G (97.79%) and 5G (95.29%). Consumers with very old handsets and some IoT devices will need migration plans.
