Best Internet Providers in Idaho Falls, Idaho


What is the best internet provider in Idaho Falls?

You can’t go wrong with any of the six internet service providers in the Idaho Falls Fiber Network, a “not-for-profit” utility owned by the city. You’ll have to pay a $25 monthly fee to maintain the city’s fiber infrastructure, but the plans are so cheap that they’re still the best deals by a long shot. (A note of caution: One Reddit user, who said they install fiber in Idaho Falls, called Fybercom the “worst by a huge mile” of the six ISPs on the Idaho Falls Fiber Network.)

My favorite ISP on the Idaho Falls Fiber Network is ConnectFast. You’ll get 1,000Mbps of upload and download speed for just $40 a month (before the $25 infrastructure fee). That kind of value is practically unheard of in the broadband world. 

If you want to pay the lowest possible prices, Sparklight offers the cheapest internet in Idaho Falls, with plans starting at $25 monthly for 100Mbps download and 20Mbps upload speed. After a year, the price increases to $50 a month. T-Mobile Home Internet is another solid option, offering fixed wireless internet for $50 monthly. T-Mobile guarantees it won’t ever raise your rates, and equipment is included in the price.

CNET considers speeds, pricing, customer service and overall value to recommend the best internet service in Idaho Falls across a number of categories. Our evaluation includes referencing a proprietary database built over years of reviewing internet services. We validate that against provider information by spot-checking local addresses for service availability. We also do a close read of providers’ terms and conditions and, when needed, will call ISPs to verify the details.

Despite our efforts to find the most recent and accurate information, our process has some limitations you should know about. Pricing and speed data are variable: Certain addresses may qualify for different tiers of service and monthly costs may vary, even within a city. The best way to identify your particular options is to plug your address into a provider’s website. 

Also, the prices, speed and other information listed above and in the provider cards below may differ from what we found in our research. The cards display the full range of a provider’s pricing and speed across the US, according to our database of plan information provided directly by ISPs, while the text is specific to what’s available in Idaho Falls. The prices referenced within this article’s text come from our research and include applicable discounts for setting up automatic payments each month — a standard industry offering. Other discounts and promotions might be available as well, for things like signing a term contract or bundling with multiple services.

Best internet in Idaho Falls, Idaho

As part of the Idaho Falls Fiber Network, ConnectFast offers one of the highest-value plans I’ve seen from an internet provider. For $40 a month (plus a $25 network maintenance fee), you’ll get upload and download speeds of 1,000Mbps. For comparison, CNET’s pick for the best fiber internet nationwide is AT&T Fiber, which charges $80 for the same speeds. ConnectFast is one of the newer ISPs to join the network, but early reviews have been positive. People on the Idaho Falls sub-Reddit say they’ve “never had a problem” and “not a single issue to be had.”

As good as the Idaho Falls Fiber Network is, it doesn’t technically have the cheapest internet in the city. That title goes to Sparklight, which offers plans starting at just $25 a month for 100/20Mbps speeds. The price increases to $50 in year two, but that’s still slightly cheaper than any of the fiber ISPs, which start at $60 after you factor in the network maintenance fee. Sparklight charges $12.50 monthly for a modem and router, but you can also use your own equipment.

If you don’t want to worry about buying your own equipment and setting up an installation appointment, T-Mobile Home Internet offers a simpler alternative. Everything you need is included in its $50 monthly price, and setup only takes about 15 minutes. T-Mobile also guarantees that it won’t ever raise your rates, and you can save an extra $20 a month by bundling with an eligible cellphone plan.

What’s a good internet speed?

Most internet connection plans can now handle basic productivity and communication tasks. If you’re looking for an internet plan that can accommodate videoconferencing, streaming video or gaming, you’ll have a better experience with a more robust connection. Here’s an overview of the recommended minimum download speeds for various applications, according to the FCC. Note that these are only guidelines — and that internet speed, service and performance vary by connection type, provider and address.

For more information, refer to our guide on how much internet speed you really need.

  • 0 to 5Mbps allows you to tackle the basics — browsing the internet, sending and receiving email, streaming low-quality video.
  • 5 to 40Mbps gives you higher-quality video streaming and videoconferencing.
  • 40 to 100Mbps should give one person sufficient bandwidth to satisfy the demands of modern telecommuting, video streaming and online gaming. 
  • 100 to 500Mbps allows one to two people to simultaneously engage in high-bandwidth activities like videoconferencing, streaming and online gaming. 
  • 500 to 1,000Mbps allows three or more people to engage in high-bandwidth activities at the same time.

How CNET chose the best internet providers in Idaho Falls

Internet service providers are numerous and regional. Unlike the latest smartphone, laptop, router or kitchen tool, it’s impractical to personally test every ISP in a given city. So what’s our approach? We start by researching the pricing, availability and speed information drawing on our own historical ISP data, the provider sites and mapping information from the Federal Communications Commission at

But it doesn’t end there. We go to the FCC’s website to check our data and ensure we consider every ISP that provides service in an area. We also input local addresses on provider websites to find specific options for residents. We look at sources, including the American Customer Satisfaction Index and J.D. Power, to evaluate how happy customers are with an ISP’s service. ISP plans and prices are subject to frequent changes; all information provided is accurate as of the time of publication.

Once we have this localized information, we ask three main questions:

  1. Does the provider offer access to reasonably fast internet speeds?
  2. Do customers get decent value for what they’re paying?
  3. Are customers happy with their service?

While the answer to those questions is often layered and complex, the providers who come closest to “yes” on all three are the ones we recommend. When it comes to selecting the cheapest internet service, we look for the plans with the lowest monthly fee, though we also factor in things like price increases, equipment fees and contracts. Choosing the fastest internet service is relatively straightforward. We look at advertised upload and download speeds, and also take into account real-world speed data from sources like Ookla and FCC reports.
