California Lifeline Program

California LifeLine Program provides discounted basic residential telephone service to low-income Californians. The discount program is provided by local telephone companies, including Sebastian, and sponsored by the California Public Utilities Commission (CPUC).

New applications for the California LifeLine Program must be approved before the California LifeLine discounts are received. If you enroll in the program, you will be required to pay the regular non-discounted rates for basic phone service until your application is approved. Interest-free payment plans are available to help pay for any applicable connection charges, service conversions, and/or deposits. Once approved, you will receive a bill credit with the California LifeLine discount retroactive to the date your service began or the date you requested enrollment, whichever is later. If your bill has a credit balance of $10.00 or more, you may request a refund check.

For more information, call the California LifeLine Program toll-free at 1–877–858–7463 or TTY 1–888–858–7889, from 7:00 a.m. to 7:00 p.m. Monday through Friday, or visit their website.

Monthly LifeLine Rate

Kerman:     $4.98/ $6.98
Foresthill:   $7.40/ $9.40

Your LifeLine rate is dependent upon state/federal qualification criteria.

As of 2021, some major internet service providers are increasing data caps throughout the U.S. Sebastian remains one of few providers that has no data caps on all internet plans, even throughout the increased usage rates during the COVID-19 pandemic. If you have any questions regarding this policy, please contact your local Sebastian office.
