1. Race Communications

If you’re looking for the best internet provider in California, Race Communications is hard to beat. Unlike many big-name ISPs, Race is a local company focused on bringing fiber-to-the-home (FTTH) to communities across California, even in places larger providers often overlook.

What you get with Race:

Symmetrical speeds up to 10 Gbps. Perfect for streaming, gaming, video calls, and working from home, all at once, on multiple devices.

Race CommandIQ®. A complementary mobile app helps you manage your home Wi-Fi from your phone with easy parental controls, device monitoring, and built‑in cybersecurity that blocks threats automatically.
Local customer support from real people right here in California, not outsourced call centers.

Race Communications offers flexible plans for different needs:

Beyond reliable fiber internet, every Race plan includes built‑in cybersecurity, expert help finding the best router placement in your home, and a premium Wi‑Fi experience that rivals national providers — often at a lower cost.

With transparent pricing, no hidden fees, and support you can actually count on, it’s no wonder more families and businesses are making the switch to Race.

2. AT&T Internet

AT&T is one of the largest internet providers in California, with a mix of technologies depending on where you live. In many cities and suburbs, AT&T Fiber delivers ultra-fast, reliable service with no data caps.

However, if fiber hasn’t reached your area yet, you may only be offered DSL or AT&T Air (5G home internet), which can be slower and less reliable.

What you get with AT&T:

Up to 5 Gbps speeds on fiber. Excellent for streaming in 4K, heavy gaming, and working from home.
No data caps on fiber plans. Unlimited browsing, gaming, and streaming without limits.
AT&T Smart Home Manager app. Manage your Wi-Fi, set screen time limits, and keep your network secure.
No contracts required. Stay flexible with month-to-month service.

AT&T Fiber pricing:

500 Mbps – $65/month

1 Gbps – $80/month

2 Gbps – $145/month

5 Gbps – $245/month

If you’re offered AT&T Air (5G; $60/month) instead of fiber, speeds are often much lower, and performance can vary depending on your signal strength and network congestion.

In California, AT&T Fiber is available in communities like Chico, Chowchilla, Lodi, Marysville, Merced, Olivehurst, Palmdale, Porterville, and Tulare. In these areas, fiber delivers excellent reliability and speed.

However, many communities only have access to AT&T Air (5G home internet) — including Colusa, Farmersville, Golden Hills, Lancaster, Mojave, Nevada City, Ridgecrest, Sutter, Tehachapi, Turlock, and Yuba City.

While AT&T Air can be a good option where fiber isn’t built yet, performance can vary depending on location, terrain, and network congestion.

3. Spectrum

Spectrum is one of the largest cable internet providers in California, covering both big cities and smaller towns. Many families choose Spectrum because it’s widely available and doesn’t come with data caps — which means you can stream, game, and work without worrying about overage fees.

What you get with Spectrum:

Up to 1 Gbps download speeds. Great for households that stream, work remotely, and game online.
Upload speeds are much lower — often under 35 Mbps. Video calls, file uploads, and gaming may not run as smoothly as with fiber providers.
No contracts and no data caps. Change plans or providers without early termination fees.
Self-installation costs $30. Professional install fee is $65.
Router rental is $10/month. Unless you bring your own router.

Spectrum plans and pricing:

100 Mbps – $30/month (entry plan; may not meet new FCC speed standards)

500 Mbps – $40 to $50/month

1 Gbps – $70/month

When it comes to Spectrum, the advertised price is rarely the price you actually pay. Their Wi-Fi router costs an extra $10 every month, adding up to $120 a year unless you bring your own.

Installation isn’t free either — self-installation runs $30, while professional installation costs $65.

And perhaps the biggest sting comes after the first year or two, when Spectrum’s so-called “introductory rates” expire and your bill jumps by $20 to $30 a month. Over time, these hidden costs make Spectrum far more expensive than it first appears.

Spectrum is available in communities like Desert Hot Springs, Farmersville, Lancaster, Palmdale, Phelan, Porterville, and Tehachapi. In many of these areas, if fiber service isn’t available at your address, Spectrum is often the only high‑speed option left.

This lack of alternatives is a big reason so many households end up with Spectrum, even though the long‑term costs and slower upload speeds leave much to be desired.

4. unWired Broadband

unWired Broadband is a Fresno‑based provider focused on bringing internet to rural and semi‑rural parts of California that larger companies often skip.

Their service is delivered via fixed wireless technology, which uses radio signals from towers to connect a small antenna at your home.

More recently, they launched NextGen Fiber, a fiber‑to‑the‑home brand available in select Central Valley cities.

unWired Broadband plans and pricing:

unWired Broadband (fixed wireless)

400 Mbps – $149.99/month

NextGen Fiber

250 Mbps – $69.99/month

500 Mbps – $89.99/month

1 Gbps – $99.99/month

2 Gbps – $149.99/month

5 Gbps – $249.99/month

unWired serves rural communities in Butte County, Colusa County, and Sutter County, with its new NextGen Fiber expanding into cities like Coalinga, Parlier, Gustine, and Wasco. For households without access to fiber or reliable cable, unWired often provides the only high‑speed option.

4. Xfinity

Xfinity (Comcast) is one of the biggest internet providers in California. They’re known for offering fast speeds and wide coverage. But while the speeds are impressive, customers often run into surprises in the form of price hikes and extra fees.

What you get with Xfinity:

Download speeds up to 2.1 Gbps. Upload speeds up to 35 Mbps, which can make video calls laggy, uploading large files slow, and online gaming frustrating.
Pricey installation. The “self‑install” kit costs $39.99. If you need a technician, it jumps to $100.
Data isn’t truly unlimited. Most plans include a 1.2 TB cap, and going over means $10 charges per 50 GB. To avoid that, you’ll need to pay $30 extra per month for unlimited data or sign up for their costly xFi Complete add‑on.

Xfinity pricing:

300 Mbps – $55/month

500 Mbps – $60/month

1 Gbps – $65/month

1.2 Gbps – $85/month

2.1 Gbps (select areas) – $105/month

Upload speeds top out at just 35 Mbps, and many plans include a 1.2 TB monthly data cap unless you pay extra. For households that rely on video calls, cloud storage, or online gaming, these limits can quickly become frustrating.

Xfinity is available in California communities like Atwater, Chico, Chowchilla, Colusa, Lodi, Marysville, Merced, and Tulare. While it offers gigabit‑level download speeds in these areas, customers often find the experience less appealing once the hidden fees and price hikes set in.

5. Frontier

Frontier has been working hard to rebuild its reputation in California. In areas where Frontier has rolled out fiber internet, the service is fast, reliable, and a strong alternative to cable. But in regions still served by Frontier’s older DSL network, speeds can feel outdated and unreliable.

What you get with Frontier:

Fiber plans up to 7 Gbps. Among the fastest speeds offered by a major provider.
No data caps. Stream, work, and game without limits.
Free installation and router. Included with most fiber plans.
MyFrontier app. Manage billing, appointments, and even connect directly with technicians.

Frontier pricing:

500 Mbps – $29.99/month

1 Gbps – $49.99/month

2 Gbps – $62.99/month

5 Gbps – $89.99/month

7 Gbps – $109.99/month

Frontier’s prices look great at first, but they are introductory rates. Expect increases after the first 12 months. For example, the 1 Gbps plan jumps to $59.99 after 12 months.

In Desert Hot Springs, Lancaster, Phelan, and Ridgecrest, Frontier has rolled out plans up to 7 Gbps. On paper, that sounds great. But Frontier’s customer service is notorious for being hard to reach and slow to resolve problems. Many customers complain that even getting their own billing errors fixed can take multiple calls.
