Inexpensive high-speed internet with no contracts

T-Mobile provides an inexpensive 5G internet plan with no contract and decent speed, but not a lot of choices or professional installation.

What we like

  • One low price
  • No commitment
  • Relatively fast
What we dislike

  • Not widely available
  • No professional installation available
  • Inconsistent speeds
Savings tip: T-Mobile often has sign-up promotions for first-time customers. Call to ask a rep about current deals and discounts.

Hyper-gig download speeds and improving customer service

Xfinity is a fantastic provider overall. It offers fast speeds, reliable service, and reasonable prices. Some plans still require contracts, and others still have data limits. Watch out for Xfinity’s hidden fees and spotty customer service record, but it may not be as bad as it once was.

What we like

  • Consistently fast speeds
  • Wide availability around the country
  • Competitive pricing, especially for budget plans
What we dislike

  • Data caps on slower plans (unless you pay more)
  • Inconsistent pricing and speed availability
  • Reputation for poor customer service

Fast, reliable fiber for larger households and power users

Ziply offers great pricing for medium-to-large households and absurdly fast internet for power users. This provider has a few quirks, like hidden contracts and no self-setup, but if those don’t bother you, Ziply is a solid internet service provider in the Northwestern US.

What we like

  • Low prices
  • Fast internet
What we dislike

  • Hidden contracts with promotional pricing
  • No self-setup

One plan, one very low price

T-Mobile 5G Home Internet comes in one download speed (182 Mbps), which is fast enough for a lot of people but slower than most cable plans (up to 1 Gbps) and fiber plans (up to 5 Gbps). The good news? T-Mobile’s plan includes unlimited data, but there may be slowdowns when the network is congested. It’ll cost you $50, which is $0.50 per Mbps, and about right for 5G plans. However, overall, 5G internet is super cheap compared to other kinds of broadband internet. The Federal Communications Commission (FCC) benchmarks similar broadband plans at $105.67/month, (1) which comes out to more than a dollar per Mbps!

Even better, if you’re already a T-Mobile customer with a qualifying Magenta plan, your rate is $25/month. If max download speeds of 100 Mbps works for you, T-Mobile 5G Home Internet is a pretty sweet deal, especially if you’re already a customer. But if you’re looking for more plan options, you won’t find them here.

Budget broadband internet plans are a great deal

Xfinity is generally a very good value, especially at the middle and lower tiers. In fact, it offers some of the best budget plans of any of the major internet service providers, with a 50 Mbps Internet Essentials plan for less than $20 per month and a 400 Mbps plan for $50 per month in some areas. Those plans have a data cap of 1.2 terabytes per month, which is disappointing but common among cable internet service providers (ISPs). Removing it costs an extra $30.

The 400 Mbps plan, which is about right for an average family, is also a great price. It rings in at about 36% of the national benchmark in its range. (1) That means you're paying just $0.18 per megabit, with plenty of megabits to go around.

Faster plans are available, but they are pretty pricey compared to the best fiber internet competitors we reviewed. Some areas can get speeds up to 2 Gbps, and others can get plans as fast as 6 Gbps. That is ludicrously fast, but it’s also really expensive. Most households don’t need those internet speeds unless they’re streaming a ton of 4K content at the same time or have 10 or more users, so we don’t recommend them for most households. They do come with unlimited data, though, so might still be worth it for some households.

Low-cost internet plans—unless you want the fastest speeds possible

Overall, Ziply offers fast fiber internet at great prices. Its slowest plans (50 Mbps and 200 Mbps) are the best value, priced at 25% and 33% of the national benchmark, respectively. (1) Its 1 gig plan is relatively more expensive, but it still comes in under 45% of the national benchmark for similar plans. After introductory pricing ends, your monthly bill will increase by about $20 per month, but you’ll still pay less than average. Plus, you’ll get unlimited data.

If you want the absolute fastest internet possible, Ziply also offers 2- and 5-gig plans, but these come with much higher price tags. A 2-gig plan is nearly double the cost of a 1-gig plan (no bulk discount here), and a 5-gig plan is nearly 4 times the cost! (2) And there’s no introductory pricing for these blazing-fast plans. You’ll also need to spring for your own router (the Ziply one doesn’t support these speeds). 1 gig should be more than enough speed to cover the vast majority of households, so we don’t recommend springing for these plans unless you’re sure you need them.

Faster than advertised, but awkwardly unpredictable

As with any fixed wireless internet provider, speeds fluctuate widely and can be affected by weather, terrain, peak hours, and more. That means you’ll rarely get a steady 100 Mbps. T-Mobile says you’ll likely see anywhere from 33 to 182 Mbps for download and 8 to 25 Mbps for upload. (2) But we think T-Mobile should toot its horn a little louder. Independent research shows speeds average out to around 119 Mbps for download and 16 Mbps for upload—both of which leave other wireless ISPs in the dust. (3)

Generally, 5G internet isn’t as fast as cable internet (up to 1,000 Mbps, or 1 Gbps) or fiber (up to 5 Gbps). But for most people, it’ll feel pretty zippy. Unfortunately, if you’re using your connection for gaming, the inconsistency could cause unpredictable, frustrating lags.

Some of the best internet reliability we found

Xfinity internet performance is excellent. Its speeds are fast and reliable. In fact, in many markets, it has one of the fastest internet speeds around. The service is reliable and consistent. If outages occur, Xfinity is responsive and generally restores service within hours. Xfinity internet is also highly rated for speed (2), and research from the US Federal Communication Commission (FCC) scored it among the top for reliability (3).

Fast, reliable fiber in most areas

Ziply has a fiber optic network, which is the most reliable kind of infrastructure out there. Fiber also allows for faster speeds than any other kind of internet, including upload speeds that are just as fast as download speeds (AKA symmetrical speed). Unfortunately, Ziply’s 1-gig plan isn’t symmetrical, serving up only 35 Mbps for upload, and that’s a shame. Still, most families will find a symmetrical 200 Mbps connection plenty fast, while high-powered users can opt for a 2- or 5-gig symmetrical plan (though it’ll cost you big).

Other than that, Ziply performs pretty well. It typically uses only 40% of its infrastructure capacity (3), which means you’re less likely to see slowdowns during peak hours. However, Ziply has legacy DSL infrastructure in some rural areas and tends to perform slower than other DSL providers.

Equipment and installation

You’ll need an app for that

T-Mobile uses a 5G gateway (included at no additional cost) to turn cell signal into Wi-Fi for your home. It’s strong enough to send signal about 30 feet away, depending on how many walls are in the way. It’s compatible with most mesh network extenders. Plus, you can create up to four separate networks, so you can create one for Airbnb guests or your least favorite roommate.

According to T-Mobile, installation should take around 15 minutes—if you have an Android or iOS phone and can download the T-Mobile internet app. If that doesn’t work out, you can call T-Mobile customer service and someone will help you get set up. If you don’t get cell signal or a landline at home, though, you’re going to have a rough day.

Equipment and installation

Typical installation fees and Wi-Fi equipment

Xfinity internet offers the usual choice of professional and self-installation. The professional option is often more affordable than competitors, at $100. It's required if you haven't had Xfinity service at the address for more than 12 months. The self-install kit is free, though you may pay for shipping and handling. If you have trouble installing yourself, you can contact customer service for help but may face long hold times.

As for equipment, the Xfinity xFi gateway is fairly typical (and costs a fairly typical $14 per month). You can also add a Wi-Fi extender (and unlimited data) if you bump up to xFi Complete for about $15 per month for the first two years (and $25 per month starting in year 3). This is a bit steep for just the extender—you can grab an excellent Wi-Fi extender for right around $50. However, using Xfinity's equipment gives you unlimited data, and you qualify for a free upgrade after three years.

If you use your own equipment, unlimited data costs an extra $30 per month for lower tier plans, but is included for plans of at least 1 Gbps.

Equipment and installation costs mostly balance each other out

Ziply’s equipment costs can add up. Its router/modem combo is a reasonable $10 per month, but its Whole Home Wi-Fi costs $20 per month. Sometimes, Ziply runs promotions that include Wi-Fi, so keep an eye out for those. Ziply’s Wi-Fi is Wi-Fi 6 technology, which is the best technology available. You can stream up to 12 devices at once (Wi-Fi 5 allows only up to 5). However, Ziply’s router isn’t compatible with its 2- and 5- gig plans. If you want one of these plans, you must BYO router, and not all routers are compatible, so be careful here.

Professional installation is free, which is great because Ziply doesn’t have a self-install option. Technicians will run cables from the street to your home, wire up your house, and set up your Whole Home Wi-Fi. The downside is technicians likely won’t get all this done in a single visit, so it might take a few weeks to get you up and running.

Award-winning customer service, but a lackluster guarantee

T-Mobile is fairly new to providing home internet, but it has a solid track record of providing great service to its mobile customers. Both contract and non-contract customers see the best service in the industry, according to J.D. Power. (4)

We don’t like T-Mobile’s short 15-day money-back guarantee, which doesn’t give you much time for a test drive. (We much prefer Starry’s 30-day guarantee.) Even worse, your countdown starts when T-Mobile ships your 5G Gateway, not when it arrives. If there are any shipping delays or it takes you a day or two to get set up, you’ll run out of testing time fast.

Rapidly improving customer service scores

The Xfinity internet customer experience is kind of a mixed bag. On the one hand, you have reliable service, with the option for unlimited data if you want it. This makes for a great day-to-day experience.

On the other hand, Xfinity internet has a spotty customer service track record. Technically, it ranks above average on customer surveys (4). That said, we all remember the memes from a few years ago. While customer service seems to be improving (based on survey scores, at least), not everyone has a great experience, and we still see a lot of complaints about billing issues and miscommunication between the company and the techs it hires.

If you need to connect with the company, we recommend using its customer service portal and downloading the Xfinity app first before trying to reach reps by phone.

Could be more customer-friendly with more self-help options and better transparency

We love that Ziply provides professional installation for free, but we’re bummed that it doesn’t even offer a self-setup option. Ziply has some great self-help content on its website for troubleshooting or changing out your router later—you just can’t use it to get started. Forcing you to use professional installation also means it takes longer to get started, and that’s tough if you’ve just moved to the area. If you’re not moving, it still means you’ll have to juggle your old service with Ziply installation times to avoid a gap in internet service.

We’re also not a fan of Ziply’s hidden contracts. It advertises no-contract plans, but if you read the fine print, you’ll pay early termination charges if you try to leave before your promotional plan ends. All that said, Ziply’s customer service is decent, and most negative reviews call out the same kinds of issues other providers get: billing disputes. (4)
