California fires back at AT&T’s bid to get feds to let it stop providing landline service
California officials and the California Public Utilities Commission sent a letter to the FCC urging it to reject or slow AT&T’s petitions seeking to end landline service. AT&T says it wants to disconnect as early as June 1, 2027, and argues it spends about $1 billion annually in California. The state says AT&T hasn’t shown cellular coverage or its “AT&T Phone – Advanced” would not harm consumers, especially in rural and low-income areas.

Regulatory/legal uncertainty over AT&T’s ability to discontinue landlines in California could affect expected network costs, timelines, and risk premium.
AT&T is seeking FCC permission to end California landline obligations, while California regulators ask the FCC to reject or slow the petitions.
Near-term: modest downside bias as the dispute raises execution risk; longer-term: direction depends on court/FCC outcomes.
Background
AT&T is the “carrier of last resort” in much of California due to prior monopoly status and state requirements to provide voice service; California previously rejected AT&T’s 2023 plan after an administrative judge found proposed replacements insufficient.
Why it matters
California’s letter to the FCC challenges AT&T’s evidence that cellular/broadband replacements won’t harm the public and disputes the affordability and coverage adequacy of AT&T’s “Phone – Advanced” device. The dispute is now in federal court and before the FCC, with a near-term procedural deadline for California’s response.
Market relevance
This is a telecom regulatory modernization dispute with potential cost/timeline implications for AT&T’s legacy network exit in California.
Market effects
Could reinforce regulatory scrutiny on telecoms’ legacy network discontinuation plans and replacement adequacy claims.
California-specific obligations may delay or constrain landline exits for carriers serving the state.
Sets a precedent for how federal vs state authority is handled in telecom modernization disputes.
Alternative perspectives
Even if California opposes, FCC streamlined processing and federal preemption could still allow AT&T to proceed, limiting ultimate financial impact.
The article cites AT&T’s $1B/year California landline maintenance cost and a proposed $45/month replacement; actual customer migration rates and litigation outcomes will likely matter more than the equity/public-safety arguments alone.
