AT&T vs T-Mobile: How Do They Compare?

Last Updated:

Chances are your cell phone service runs on one of the four largest mobile networks in the United States - Verizon, Sprint, AT&T, or T-Mobile.

The problem is that all four of these providers do their best to convince you their LTE network is the fastest and best cell phone network out there.

The truth is that no matter whose cell towers you use you're likely to get pretty reliable service with high speeds for browsing the web, streaming music, and watching high-definition video.

But what about things like network coverage and plan costs? If you're trying to figure out which network is better between AT&T and T-Mobile you're in the right place.

I'm going to give you the lowdown on coverage and tell you how to save money while enjoying great service on whichever network you choose.

How to Switch to a Big Network without Paying Big Prices

Whether you settle on the AT&T or T-Mobile network you may be under the impression that you're stuck paying those specific carriers' rates.

What if I told you that you can have mobile service on these reliable networks without the high plan costs? Small carriers called Mobile Virtual Network Operators (MVNOs) give you that very option.

Not only are these alternative providers widely available, but they're also on a sharp rise. According to Allied Market Research there are over 100 MVNOs in North America and the market is set to grow more than 10% by 2023.

Benefits of MVNOs:

  • Cheaper prices - MVNOs buy the use of the big four networks and resell no-contract plans to you at a deep discount.
  • Prepaid phone plans meaning no contracts or early termination fees.
  • Bring your own phone and keep your number.
  • Custom plans - buy only the minutes, texts, and amount of data you need.
  • Easy to sign up - typically everything is done online.
  • Alternative mobile carriers have the highest customer satisfaction ratings.

Next, we'll look at a few of the plans offered by AT&T MVNOs vs. T-Mobile MVNOs.

AT&T vs. T-Mobile MVNO Plan Comparison

Cell phone plans from low-cost carriers vary just as much as - if not more than - those from the big four.

You've got a multitude of options.

Best Cheap Cell Phone Plan - Mint Mobile (T-Mobile Network)

Are you shopping for basic service like a senior cell phone plan or maybe an emergency phone for a child? Here are a couple examples of affordable cell plans:

Best Unlimited Data Plan - Textnow (T-Mobile Network)

Do you burn through data like crazy? Save money on unlimited data plans by shopping alternative wireless carriers.

Pro Tip: The average data usage of smartphone owners is less than 4 GB per month. Check out our data calculator to see if you really need an unlimited plan.

Best Family Phone Plan - Textnow (T-Mobile Network)

It's true that most MVNOs don't offer a traditional family cellphone plan. However - their rates are so much cheaper than other carriers that you'll typically save a ton of money even with multiple lines.

Best Prepaid Plan - Textnow (T-Mobile Network)

Most MVNOs work on a prepaid basis. This allows you to ensure that you don't have any unexpected data overages, taxes and fees at the end of the month.

Network Coverage Comparison

When it comes to coverage, which is on top: T-Mobile or AT&T?

After all, you need coverage in order to make calls or use your data. And there are plenty of instances where you may need both. Lost in a desert? You will need your GPS, which requires data. Taking a cross-country trip and want to stream video for the kids? You'll need cell reception.

This overview should help you figure out which network is better for your needs.

T-Mobile Coverage

T-Mobile USA is no slouch in the mobile industry. The Uncarrier took five of the six mobile network awards given by OpenSignal in 2017. Average download speeds of 19.4 Mbps make the network the fastest 4G LTE service available.

As far as coverage, the T-Mobile LTE network is incredibly strong and reliable in urban areas. Reception and speed have suffered a bad rap in rural areas, however, T-Mobile is making significant strides toward improving the situation. In fact, as Spectrum Gateway shows, the company is in the process of expanding its coverage on a large scale.

Weak/No Coverage Areas:

  • Spotty areas through the South and Northeast
  • Large portions of Washington, Idaho, Oregon, and Nevada
  • Streaks down the east and northwest areas of California

Many of the weak areas on the T-Mobile coverage map are rural and largely unpopulated. Others fall within the range of new coverage T-Mobile is deploying.

Lastly, as far as reliability, T-Mobile customers get a 4G LTE signal 93.1% of the time (as opposed to 3G speeds), putting the network in the top spot for LTE access.

AT&T Coverage

AT&T coverage is extensive, no doubt about it. The network does have some weak areas in the west, as do all the carriers, with some of those areas being covered by 3G service from third-party networks.

Weak/No Coverage Areas:

  • Northern Montana
  • Central Nebraska, Wyoming, Nevada, and Idaho
  • Western New Mexico
  • Northern Arizona
  • Northwestern California

Overall, AT&T's LTE coverage is strong, with its users getting a 4G LTE signal 86.9% of the time.

T-Mobile takes the win in speed between these two networks with AT&T the victor in overall LTE coverage.

Customer Service

Now we know MVNOs offer cheap cell phone service. But that's not all that matters - you want attentive and effective customer support as well. How do MVNOs measure up?

You may be surprised to learn that not only do alternative carriers hold up to the big guys when it comes to taking care of you, they actually beat out the major carriers.

In Consumer Reports' 2017 Cell-Phone Service Survey, Consumer Cellular, Project Fi, and Ting took the top three positions for consumer satisfaction, reliability, and customer support.

Phone Options

Once you've chosen either the T-Mobile or AT&T network you'll need to decide what device to use. Some MVNOs offer new phones for sale, however, this is seldom a cost-effective option.

It may be time to change the way you think about your smartphone. New flagship models like the Samsung Galaxy come out every year or so, but do you really need the newest upgrade every single time it comes out?

Changes to models are typically slight, yet these devices range from $400-$1,000 - that's a big investment when your phone probably has at least a couple more years left in it.

So what should you do? One of the best ways to save money on your cell phone is to either bring your own device with you or buy a used smartphone.

Benefits of BYOP (bring your own phone):

  • Save up to $30 a month per line on device payments.
  • Easily swap SIM cards out to switch carriers.
  • Keep flexibility - not tied to a carrier to whom you owe monthly installments.

Just make sure your device is unlocked. Check out our guide on how to unlock your phone.

Buying a used phone offers similar advantages, along with the ability to save up to 50% off the cost of your device. Companies like Decluttr and BuyBackWorld make it simple to not only get a quality smartphone but also sell your current one.
