T-Mobile 5G Home Internet has one simple plan and is widely available across the U.S. We don’t like how it offers a wide range of download speeds, but you can save $20 per month when you bundle your internet with cellular service.

AT&T Fiber offers five plans to fit your home’s needs, but like most fiber internet providers, its service is limited across the country. If available in your area, AT&T gives you a $20 discount when bundling with AT&T Wireless.

Now, let’s dive deeper to find which internet provider is best for you.

Find out if these internet service providers are available in your area.

Winner: AT&T Fiber

AT&T Fiber is a better value because it guarantees faster speeds for only $5 more per month than T-Mobile 5G Home Internet’s plan.

T-Mobile 5G Home Internet offers one plan that gives you unknown speeds with a huge range between 72 and 245Mbps (based on your signal and network congestion). But there are two reasons you should get this internet service provider.

First, T-Mobile makes bundling your internet service with mobile easy and affordable—everyone needs cell service, of course. And when you bundle your T-Mobile cell phone and internet services, you’ll get $20 off your monthly bill.

The second reason is T-Mobile Internet is available in 40 different states, making it the most widely available 5G internet provider in the U.S. AT&T Fiber is only available in big cities in 21 states.

T-Mobile 5G Home Internet vs. AT&T Fiber: Internet speed

Winner: AT&T Fiber

AT&T Fiber has faster speeds than T-Mobile 5G Home Internet.

AT&T uses a fiber-optic connection, which is known to be reliable and faster than other broadband internet. AT&T Internet’s download speeds start at 300Mbps, whereas T-Mobile’s range doesn’t even reach that high.

With AT&T, you can get up to 300Mbps download speeds for $5 more than T-Mobile Home Internet, and T-Mobile can’t promise you’ll get speeds of 100Mbps.

AT&T Fiber’s download speeds match its upload speeds, so it can support activities that require a lot of bandwidth, like working from home, livestreaming, gaming, and downloading files.

Upload speeds ensure less lag, so T-Mobile 5G Home Internet’s 15–31Mbps upload speeds might not be a problem for those who don’t livestream or game.

What’s the difference between 5G and fiber internet?

5G Internet is a relatively new internet product that doesn’t require any wires, cables, or dish installations. It’s widely available, has a good value, and is extremely easy to sign up for and get installed. You’ll find 5G internet service from mobile providers like T-Mobile and Verizon.

Fiber internet uses fiber-optic cables to deliver the fastest and most reliable internet connection. The downside is that fiber internet is not widely available across the U.S. But if you live in an area that offers it, you can get fast speeds for an excellent price.

T-Mobile 5G Home Internet vs. AT&T Fiber: Data caps

Winner: Tie

Both T-Mobile 5G Home Internet and AT&T Fiber offer unlimited data.

You can stream, game, video conference, livestream, and internet search as much as you want without worrying about paying extra fees or internet throttling.

Internet providers with data caps can charge a hefty fee when you go over your data. Some also slow your speeds down to an annoyingly slow crawl—no need to worry about that with either of these internet services.

T-Mobile 5G Home Internet vs. AT&T Fiber: Customer service

Winner: T-Mobile

According to the American Customer Satisfaction Index (ACSI), T-Mobile ranks slightly higher than AT&T when it comes to customer service.

After interviewing over 23,600 internet customers, the ACSI found that T-Mobile was the second-best in customer satisfaction, and AT&T Internet came in third out of 10+ internet service providers.

So, with either internet provider, you won’t have to worry about difficulties contacting a real representative (instead of a bot) or receiving help to solve an issue quickly.

T-Mobile 5G Home Internet vs. AT&T Fiber: Which is better?

T-Mobile 5G Home Internet is $50 for download speeds of 72–245Mbps, and we recommend getting this broadband internet service if you’re looking for a T-Mobile phone plan or are an existing T-Mobile customer.

AT&T Fiber ranges between $55 to $250 per month for 300–5,000Mbps. For $5 more than T-Mobile Internet, you can get up to 300Mbps—or upgrade to the $65 per month plan to get 500Mbps. But make sure you live in an area with AT&T Fiber service.

Neither internet service has contracts, data caps, or price hikes.

  • Price: AT&T Fiber has a better value because you get more Mbps per dollar. For $50, T-Mobile delivers a range of 72–245Mbps download speeds, but it’s uncertain if you’ll get the high- or low-end of that range. You can get up to 300Mbps with AT&T Fiber for $55.
  • Internet speed: AT&T Fiber has a fiber-optic connection, delivering fast and reliable speeds you can’t find with wireless broadband. T-Mobile Internet is equivalent to cable internet providers, which is second-best and more available to Americans.
  • Data caps: Both internet services forgo data caps, so you can use the internet as much as you want without worrying about extra fees or internet slowdowns.
  • Customer service: T-Mobile Internet ranked a tad higher than AT&T Internet in customer service satisfaction. You can rely on both to answer technical questions or to help with bill issues.
