While many people consider only download speeds when selecting an Internet Service Provider (ISP), data caps can end up having a huge effect on your internet experience—and how much you pay for it.

Although many providers say 1 TB of data is more than enough to last most customers for a month, that’s becoming less and less true. As more people use their internet subscription to support smart home technology and 4K-movie downloads, breaking that data limit is easier than you think.

While we focus primarily on traditional television at CableTV.com, we recognize that many of our readers use smart TVs and stream their favorite TV shows. So, in this post we’ll dig deep into how to keep data caps from racking up your bill and ruining your online TV time.

Looking for a nearby internet provider with unlimited data?

Enter your zip code below and compare your results to the table above to find the right provider for you.

What is a data cap?

A data cap is an ISP-enforced data usage limit. Everything you do on the internet from streaming Netflix to scrolling through social media requires data—use the internet too much, and you might hit the limit.

Other names for data caps include “fair use policy,” “monthly usage allowance,” and “bandwidth cap.” But “bandwidth cap” is a bit of a misnomer because most internet providers won’t slow—or throttle—your speeds if you surpass the limit.

Instead, your provider will usually send a warning when you’ve neared and passed your usage limit, and then you’ll receive overage charges on your next bill.

The exceptions to this rule are satellite internet providers like HughesNet and Viasat, which offer plans based on data caps, not varying download speeds. After you reach the data limit with these providers, you’ll still be able to use your internet, but your speed will be throttled.

Why do providers use data caps?

While caps can be frustrating for subscribers, ISPs that cap data claim the ultimate goal of these caps is to provide a better internet experience for all customers.

ISPs can produce only so much bandwidth and capacity, so excessive use from a few users can lead to slower speeds for the rest of the provider’s consumer base. As a result, many providers call their data policies “fair use policies,” emphasizing that the aim is to provide fair access for all subscribers.

Rather than limiting all customers, ISPs that don’t cap data deal with the problem by reaching out to individual users who are causing issues. This case-by-case approach allows these ISPs to offer their users unlimited data—at least until too many data-draining customers prove to be a problem for the rest of the network.

What uses up the most data?

Everything from email to online gaming takes up data, but aside from regularly downloading massive files, streaming TV probably puts the heaviest strain on your data usage.

Netflix claims streaming Full HD uses 3 GB per hour, and 4K Ultra HD uses 7 GB per hour. With the common data cap of 1 TB, you can stream about 333 hours in Full HD or 143 hours in 4K Ultra HD per month. That’s plenty of data if you don’t have a large household or if you’re not a big binger.

What does 1 TB Look Like in 4K vs HD Hours
What does 1 TB look like?

Consider what one month might look like with a household of four TV lovers:

  1. One unwinds on weeknights with The Crown. (19 hours)
  2. Another is re-watching all of Game of Thrones. (63 hours)
  3. A third watches a couple of hours of anime every night. (60 hours)
  4. A fourth keeps up on the newest Netflix series every weekend. (40 hours)

That puts the household at a total of 182 hours. Assuming they’re watching in Full HD, that’s just over half a 1 TB limit. Even with adding on some video chats, game downloads, and browsing, this household of TV lovers will likely finish the month well under their data cap.

But if your household has more people, watches 4K, or binges more TV than this, you should seriously consider an internet plan with unlimited data.

Do all brands have data caps?

Many ISPs cap data, but not all. With internet technology advancing, some brands are raising their data ceilings, offering unlimited plans, or eliminating caps altogether.

As you read on for a more in-depth look at big-name ISP data policies, be sure to compare the list to what’s available in your area. Enter your zip code below to see your options.

How do I track my AT&T data usage?
AT&T provides an estimate of how much data you’ve used when you log into your account. Please note that AT&T will send you email notices if you’re coming close to your cap.

Does Cable ONE have data caps?
Cable ONE has a lot of data caps. Most of its plans are named after their target audience, and the download speeds and data caps associated with each plan reflect that demographic as well.

For bundled packages, the data caps are a bit smaller than the stand-alone packages with similar speeds. In contrast, many other companies incentivise bundling by raising caps or eliminating them all together. Although you’ll save money by bundling with Cable ONE, the stricter data limits are worth considering before you do.

There are a few exceptions to the data caps, though. This year Cable ONE started offering “Plus” plans without data caps in Fargo, North Dakota, and Odessa, Texas. And in Sioux City, Iowa, and Bartlesville, Oklahoma, you can add unlimited data to any “Plus” plan for $40.00 per month.

What happens if I exceed my Cable ONE data allowance?
In most regions, Cable ONE will require you to upgrade your plan after you go over your cap for three months (consecutive or nonconsecutive) in a rolling twelve-month period.

However, in Sioux City, Iowa, and Bartlesville, Oklahoma, you can get 100 GB of extra data for $10.00 (up to $50.00 max).

How do I track my Cable ONE data usage?
Cable ONE will let you know when you go over your data cap, but if you want to check how you’re doing, just log in to your account. You can even set up data usage alerts if you want to be careful.
