What's happening to traditional landlines in California

AT&T, Verizon, and Frontier have all filed petitions with state regulators to end their legal obligation to maintain copper phone infrastructure. In many states, they've already succeeded. The result: repair times are longer, outages are more frequent, and prices have been raised to a level that makes dropping the service the "obvious" choice — which is exactly the intent.

At the same time, major cable companies only offer standalone home phone service at penalizing rates. Comcast, Spectrum, and Cox make landline-only service available, but price it to push customers toward $80–120/month bundles. The phone line that cost $20/month ten years ago now costs $50+ as a standalone service — or requires an internet or TV subscription to get a "reasonable" price.

The government's response has been to deregulate, not protect. The FCC has progressively weakened landline service quality requirements, and the Lifeline program that once subsidized phone service for low-income households has been significantly reduced.

What that leaves: a reliable, no-internet-required home phone service using cellular networks. The same networks your cell phone uses. No copper line needed. No bundle required. Setup takes five minutes.

Cellular network coverage in California

Cellular home phone services use the same tower infrastructure as your cell phone. Ooma's Telo LTE uses AT&T's network. Community Phone uses T-Mobile and AT&T depending on your location. Before choosing a device, it's worth knowing which network has the strongest signal in your area — that's the network your home phone will run on.

Community Phone uses T-Mobile's 4G LTE network for cellular home phone service, and T-Mobile 4G covers 179 cities we track across California. Use the interactive map below to check T-Mobile's 4G signal strength at your address — that determines call quality on the Community Phone device.

If T-Mobile has stronger coverage in your area of California, Community Phone will typically give you better call quality. If AT&T is dominant, Ooma's LTE device is the better pick. Both providers offer a 30-day trial — you can test signal before committing.

How cellular home phone works in California

A cellular home phone base station plugs into the wall like a traditional phone jack — except instead of connecting to a copper line, it connects to a cellular network. You plug your existing analog home phone into it. Calls go over 4G LTE. The only difference from your perspective: the bill is lower and there's no landline infrastructure that can corrode, flood, or get deprioritized for repairs.

Key features to compare when choosing:

• Battery backup: Both Ooma and Community Phone include battery backup — calls work during power outages. Traditional copper lines also work without power, but VoIP and internet-based services don't. Cellular home phone is the only modern option that maintains this.
• No internet required: Cellular home phone works independently of your WiFi or broadband. If you have an internet outage, your home phone still works.
• Keep your number: Both providers support number porting — bring your existing home number.
• Equipment cost: One-time hardware purchase ($79–149 depending on provider) plus monthly service. No rental fees, no installation charges.
• International calling: Community Phone includes international calling. Ooma charges per-minute for international calls beyond a basic US plan.

California home phone service FAQs

The bottom line on home phone service in California

Traditional copper landlines in California are getting more expensive and less reliable as carriers shift their investment toward newer infrastructure. The most practical modern alternative — cellular home phone — costs less, works without internet, includes battery backup for outages, and uses the same 4G LTE networks that make cell phones reliable across the state.

Ooma is the best option if you make mostly US calls and want the lowest ongoing monthly cost. Community Phone is worth the slightly higher price if you want US-based customer support and built-in international calling.

Either way: stop paying for a copper infrastructure that the carriers themselves are trying to decommission.

Methodology: How we picked the home phone service in California

The home phone providers we recommended have been researched and evaluated based on price, coverage, customer service, and additional features. Our goal is to provide a comprehensive view that balances cost and value, helping you find a plan that fits your needs and budget.

We did consider these other alternatives: Verizon, AT&T, Xfinity, Spectrum, Optimum but we discounted them because they all require you to bundle landline service with internet at a much higher cost.
