Most satellite internet plans come with data caps, so it’s best to track how much data you use every month.
  • Satellite internet data caps limit monthly data usage to manage network traffic and maintain performance.
  • You may face throttled speeds, overage fees or service disruptions if you exceed your data cap.
  • Starlink is the only satellite provider that features unlimited data and doesn’t impose soft data caps.

Satellite internet is infamous for being slower than typical wired connections, but it’s often a saving grace for rural customers with restricted access to other internet options. Unfortunately, one big drawback to the service is having to deal with satellite internet data caps. Besides the data caps, the lack of high-speed internet options in rural or remote areas forces satellite internet users to deal with rigid policies such as data throttling, long contracts and high equipment costs. Our guide will tell you everything you need to know about satellite data caps and what you can do to prevent exceeding your monthly allowance.

Overview of Satellite Internet Data Caps

What Is a Satellite Data Cap?

A satellite data cap is the amount of data a user has each month from their satellite internet plan. Data caps allow internet service providers (ISPs) to monitor bandwidth usage on their networks and regulate traffic during busy parts of the day. Your data cap depends on your internet speed and how much bandwidth you can use, which you can check in your ISP’s residential service agreements. You can also use an internet speed test tool or bandwidth calculator tool.

Why Do Data Caps Exist?

One of the main reasons data caps exist is to manage network traffic.

Data caps help ISPs, including satellite providers, manage network traffic and maintain user performance. By limiting the amount of data a customer can use within a billing cycle, ISPs aim to prevent a few heavy users from overloading the network, which could degrade service quality for others. This is important for satellite internet, where bandwidth is more limited compared to ground-based services like fiber or cable.

Data caps also allow providers to align pricing models with usage levels, ensuring fairness and encouraging efficient resource use. Maintaining satellites in orbit and managing limited spectrum capacity is costly for satellite providers, and data caps help balance these operational challenges. Data caps are designed to optimize the network and sustain a consistent user experience, especially during peak usage times.

The use of data caps is controversial because they turn a profit for ISPs. It costs them less than a penny to deliver 1 GB to a customer, so the issue isn’t solely about maintaining infrastructure.

What Happens When Satellite Data Caps Are Reached or Exceeded?

A typical result of exceeding your data limit is slow performance and data overage fees.

When satellite data caps are reached or exceeded, satellite internet providers impose penalties in the form of soft or hard caps. If you’re unsure which cap you have on your plan, contact your ISP. Plans with hard caps may be given the choice to purchase more data, be charged for the additional data used, or have the connection completely shut off. If you have a plan with a soft cap, you’re charged overage fees or you will have your data throttled.

Throttling is when your data is deprioritized and speeds get extremely slow. It may feel impossible to stream, video chat, or even complete basic tasks like sending emails or browsing the web. Considering the existing latency of satellite technology in America, throttled speeds can feel like your internet is no longer in service.

Less than 1 percent of ISPs in the U.S. offer satellite internet, so the lack of market competition allows them to charge whatever fees they want. ISPs usually bill overage charges in one of two ways: per gigabyte or in blocks of gigabytes. If you go over your plan by 1 GB but overage charges are billed in blocks of 10 GB, for example, then you’re still billed for 10 GB. These restrictive policies and rigid fees give you few options, and the easiest requires you to comply with their data cap and reduce data usage.

How Do I Stay Under My Satellite Internet Data Cap?

Going over your data cap doesn’t have to be a given. Here are a few ways to reduce data usage to avoid exceeding your satellite internet data cap:

  • Use compression browser extensions and plug-ins. Compression extensions compress the data on a website before it loads in your browser. Google Chrome and Mozilla Firefox both have compression extensions you can install. Apple Safari doesn’t have any compression add-ons, but Chrome and Firefox are both available for macOS.
  • Stick to low-resolution settings. Be mindful of your streaming habits and set video quality accordingly. When available, watch videos in the lowest resolution to limit data usage and preserve bandwidth on your home network.
  • Change your browser and mobile settings. You can find tutorials on how to change settings in Chrome and Firefox that prevent auto-play and even disable images from loading to reserve data. If you want to minimize data usage and stop seeing pop-up advertisements, then ad blocking extensions such as Adblock Plus are available for most browsers.
  • Download content instead of streaming. Downloading and streaming use about the same amount of data, but you can download your streaming library and certain titles on Netflix to prevent excess data usage. Bandwidth limitations cause latency problems, so downloading content frees up bandwidth for other household members and improves speeds by lowering the number of concurrent devices on a home network.

Which Satellite Internet Providers Have Data Caps?

If you’re struggling to stay beneath your data cap, then it may be time to compare other providers and assess their offerings. With only five satellite internet providers in the U.S., options are scarce. Starlink, Hughesnet, and Viasat are the largest satellite providers in the country. Despite the limited alternatives, it’s worth seeing what options are available. Here’s a current list of satellite internet providers in the U.S.:

Provider Soft data cap Download speed Unlimited data
Hughesnet 200 GB Up to 25 Mbps No
Viasat 500 GB Up to 100 Mbps Yes
Starlink 850 GB Up to 220 Mbps Yes

The majority of satellite internet service providers, including Starlink and Viasat, are moving toward unlimited data, with the exception of Hughesnet. If you’re unhappy with the satellite internet market’s current offerings, you may want to consider other available options.

What Options Do I Have Besides Satellite Internet?

If you’re in a rural area with limited internet options and you want something other than satellite, then fixed wireless internet and 5G home internet are great alternatives. Fixed wireless is a method of delivering connectivity over the air. It’s a cost-effective option for customers who don’t want to invest heavily in new cable and infrastructure. 5G home internet works similarly. Fixed wireless data caps typically range from 10 GB to 10 TB, while current 5G home internet plans have unlimited data.

When choosing an internet provider, it’s a good idea to find out how much internet speed you need so your monthly billing plan aligns with your data usage.

Frequently Asked Questions about Satellite Internet Data Caps
