Methodology
Our HighSpeedInternet.com editorial team bases our analyses on customer input from our Annual Internet Service Provider Review, results from our speed test tool, and proprietary internet provider data on speeds and pricing. To strengthen our research, we look closely at provider contracts to get hard-to-find information on price hikes, data caps, and extra fees, and we keep tabs on the latest news reports and online reviews. When applicable, we also rely on our personal experiences testing these services.
Our favorite plan
The average household needs internet speeds of at least 300Mbps but not more than a gig (1,000Mbps), so the best plan we recommend for each provider is always within that range. We also consider plan specifics, like added costs or included perks, and compare all the options from each provider to national averages. Finally, we account for tech type differences, since you might not need as much speed on a fiber plan as you would on a less-reliable fixed wireless or cable plan. Learn more about how much speed you need, and enter your zip code in our provider lookup tool to see what you can get in your neighborhood.
A note about pricing
The prices you see may not reflect the standard rates these providers could charge after an introductory period. You’ll see the standard rates on broadband nutrition labels displayed during checkout, along with equipment fees, installation fees, contract requirements, and data caps (if any). Always view this information before you sign up for internet service.
