Thank you to Vicki Sievers of Marin County, CA for sending this out:

URGENT DEADLINE TO PROTECT SURVIVAL OF LANDLINE PHONE, WIRED DSL INTERNET & LIFELINE PROGRAM

ATT has sent a petition “ to retire and discontinue Copper Landline phone service or POTS= Plain Old Telephone Service.” The termination of the copper landline would also discontinue the Wired DSL internet service, since DSL wired internet relies on a landline phone connection.
ATT’s plan is to transition all landline phone services into wireless based phones, cell phones, computer phones, VOIP phones, wifi wireless modem phones, mobile phones as the only available phone internet service provided to the public. ATT has also applied to discontinue its participation in the Lifeline credit program that makes phone, internet services affordable and available to thousands of people. 
The CPUC commission will decide on June 30, 2023 on whether to reject or approve ATT’s petition to retire the copper landline and Lifeline program. 
Investment and survival of copper landline phone equipment & services and in a wired infrastructure is a large part of the solution to prevent the increased installation of cell towers with a wireless infrastructure.
📢 CONTACT THE CPUC BEFORE FRIDAY JUNE 30 TO ASK THE CPUC TO DENY & REJECT ATT’S APPLICATION TO RETIRE COPPER LANDLINE PHONE, DSL WIRED INTERNET SERVICES & THE LIFELINE SUBSIDY PROGRAM.
IF FOR ANY OF THE REASONS BELOW, YOU REQUIRE COPPER LANDLINE, WIRED DSL  INTERNET OR THE LIFELINE PROGRAM ASK THE CPUC TO PROTECT, PRESERVE AND INVEST IN THOSE SERVICES AND FOR THE CPUC TO DENY ATT’S APPLICATION TO RETIRE THOSE SERVICES OR THE LIFELINE PROGRAM.
Even if you do not require a copper landline, your calls will support those who do, and will help prevent more wireless installations. Thank you.
