AT&T is starting to pull the plug on traditional copper landlines in parts of Florida, and longtime customers are getting the heads-up in their mailboxes and on their phones. The company has begun telling residential users and small businesses that old-school dial tone over copper wire will be phased out, with upgrade offers and deadlines already rolling into some neighborhoods.
Replacement products are on the table, but the change is not just about swapping handsets. Communities that still depend on hard-wired phones for building alarms, fax lines and medical monitoring may see service changes as those copper loops disappear. Local customers and small-business owners say they are getting letters and calls that spell out timelines for conversion and, ultimately, discontinuance of legacy service.
Why AT&T is making the change
AT&T says the move is driven by the economics of keeping aging copper alive for a shrinking audience. The company calls the legacy network costly to maintain and says that only a sliver of its base is still hanging on to old landline technology. In its own words, "less than 2% of our eligible customers are still using legacy copper voice technology," and it points to replacements such as AT&T Phone Advanced, fiber-based service and wireless options.
According to AT&T, the transition will roll out over multiple years and starts in certain areas this summer, with specific neighborhoods moved over in waves rather than a single statewide cutover.
Regulatory filings and timeline
In Florida, AT&T has put its plans in writing with state regulators. Formal discontinuance paperwork filed with the Florida Public Service Commission lists November 15, 2026, as the earliest date the company could stop offering copper-based AT&T Phone in areas where it does not have fiber in place. The same filing says customer notices were mailed in November 2025.
The document, which details affected wire centers and outlines replacement options, also includes the exact customer-notice language that is landing in mailboxes. On the federal side, broader Section 214 applications that enable the change are pending at the Federal Communications Commission, which has issued public notices seeking comment on the requests under WC Docket No. 26-143.
What this means for Florida households
On the ground, Florida customers are already comparing notes. Local reporting shows letters and videos from residents in Palm Beach County and other communities who say they have received AT&T notices warning of upcoming upgrades and cutovers. As reported by Palm Beach Daily News, some are now trying to figure out whether the new gear will actually play nice with their existing alarm panels and medical monitoring devices.
In its Florida filing, AT&T says the upgraded service "supports your essential needs, including phone calls, fax machines, alarms, medical monitoring, and 911 access." Even so, consumer advocates caution that plenty of people will need help sorting through the fine print, testing compatibility and understanding price changes as they move away from legacy copper, according to Citizens Utility Board.
How to prepare
If you still rely on a landline, this is the moment to start paying close attention to the mail. Check for any notice from AT&T and call the company’s support line to confirm your options, including whether you can keep your existing phone number and what replacement products are available at your address.
AT&T says it will reach out to customers multiple times and provide a clear shutoff date along with upgrade assistance, including devices that can plug into existing in-home wiring. The company also posts customer guidance on transition steps and on backup power so that e911 continues to work during an outage, according to AT&T.
Customers who use their line for alarm systems, medical monitoring or older fax equipment are urged to contact their alarm company, healthcare provider or equipment vendor to confirm whether those devices will function properly with a VoIP or wireless replacement. A technician visit to test compatibility in real time may be worth scheduling, particularly for critical medical or safety systems.
Regulatory note
On the regulatory front, the FCC’s technology-transition rules allow discontinuance applications to be automatically granted if neither the agency nor a state regulator steps in to slow things down. Interested parties can still file comments in the docket, and the agency’s public notices spell out how customers and state commissions can object if they believe a reasonable substitute is not available, according to the FCC.
For now, Florida customers should treat AT&T’s letters and calls as the opening round of a phased conversion. Anyone who runs into trouble finding a workable alternative, or who believes they cannot safely lose copper service, can raise those concerns with regulators or consumer groups while the clock ticks toward 2026.
