Best internet plan for you

The best internet plan for you depends on a few different factors, such as the number of internet users and connected devices in your household, as well as the types of daily internet activities your household participates in. Some households have only light internet users, and therefore do not need a provider’s fastest internet option. Others are moderate to heavy users and need 500+ Mbps plans to support their daily internet activities without performance issues.

Planning on streaming Clemson or South Carolina games this college football season? Make sure you have enough speed, especially if you’ll be watching on multiple devices. We break down different types of internet users below and what speeds you’ll need:

Light internet use

1 to 2 devices: 5 to 20 Mbps

2 to 4 devices: 20 to 40 Mbps

5 to 10 devices: 50 to 100 Mbps
Moderate internet use

1 to 2 devices: 5 to 20 Mbps

2 to 4 devices: 20 to 40 Mbps

5 to 10 devices: 75 to 200 Mbps
High internet use

1 to 2 devices: 100 to 200 Mbps

2 to 4 devices: 200 to 300 Mbps

5 to 10 devices: 400 to 500 Mbps

In South Carolina, there are various providers offering a wide range of speeds to fit your needs. If you are a light user, explore the cheapest options from providers like Xfinity, Frontier and Kinetic that offer plans at $40.00/mo. or less for 200 – 300 Mbps. If you are a moderate to heavy user, explore faster fiber options from AT&T, Kinetic and Frontier, which will offer more speed, reliability and consistency that comes in handy for heavier users. Keep in mind that provider availability varies, so always check your address or ZIP code to find providers near you.

How we review internet in South Carolina

Our methodology

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction.

We evaluate broadband providers in four categories: affordability, performance, value and customer satisfaction. Each category contains multiple sub-factors, all of which are weighted differently to impact the provider’s overall score.

For each sub-factor, we score all providers on a continuous scale of one to five, relative to the industry as a whole. Because the average download speed in America is currently 290 Mbps, for example, we assigned all plans with download speeds between 100 and 299 Mbps a score between three and four. Xfinity’s 200 Mbps plan received a 3.50 score for download speed, while Spectrum’s 500 Mbps plan got a 3.71.

We only considered standardized data points in our scoring system. More abstract data like consistency of service and brand reputation is still part of our analysis, but we opted to let our writers address them in the context of each review.
