AT&T Wireless vs. T-Mobile Review 2020

It’s a Godzilla versus Mothra kind of battle between T-Mobile and AT&T, and in this case, T-Mobile plays the role of Godzilla. T-Mobile’s unlimited data plans are $5–$10 cheaper than comparable AT&T plans and offer more high-speed data. Like a good Mothra, AT&T puts up a good fight against T-Mobile with its fast download speeds and superior coverage, but Godzilla rips off its wings with its superior unlimited plans.

T-Mobile vs. AT&T individual data plans

Get the most value with T-Mobile’s Unlimited plans.

T-Mobile and AT&T individual data plans

T-Mobile offers three unlimited individual plans, and AT&T offers a variety of different data plans that range from 3 GB of data in a month to unlimited data.
You get way more value with T-Mobile’s unlimited plans.

Don’t be fooled by AT&T’s cheaper Mobile Share Plus 3GB for $50 a month—you get way more value by going with the T-Mobile Essentials plan for $60 a month. Paying an extra $10 a month to go from 3 GB of data to unlimited data is like paying an extra dollar to upgrade your personal-size pizza to the kind of pizza where you get a trophy when you finish it. Don’t even get me started on how AT&T’s 9 GB plan costs the same as T-Mobile’s basic unlimited data plan.

Generally, T-Mobile plans cost $5 less than comparable AT&T plans, except for both premium plans capping at $85 a month.

Higher data caps

AT&T’s Unlimited Starter Plan is subject to sudden data slowdowns in congested areas, whereas T-Mobile’s Essentials plan gives you a generous 50 GB data cap. In other words, your data speeds on AT&T can slow down when you need it most (like when you try to call an Uber after a big event), and with T-Mobile you have a guaranteed 50 GB of high-speed data no matter where you are.

Somehow, AT&T’s basic unlimited plan costs $5 more than T-Mobile’s basic unlimited plan, and it should really be the other way around.

T-Mobile vs. AT&T family plans

T-Mobile offers a better deal for families.

T-Mobile offers three different family plans, and AT&T serves up five different options. To the surprise of nobody up to this point in the review, T-Mobile’s family plans have way more value than AT&T’s family plans.

Get unlimited data for a family of three for $105 with T-Mobile.

The cheapest family unlimited plan from T-Mobile costs about $35 a line, whereas the cheapest family unlimited plan from AT&T costs about $45 a line. Honestly, there’s not much more that needs to be said. In fact, you can get the higher-tier Magenta T-Mobile family plan for even less than you would pay for the AT&T Unlimited Starter family plan.

The only exception to the rule is the AT&T Prepaid Multi Line Monthly Plan. Each line will cost you about $26 a month, which is cheaper than anything T-Mobile offers for family plans. The only downside is you’ll share 10 GB a month instead of having unlimited data, and you’ll need to pay your bill at the beginning of the month.

T-Mobile gets the nod over AT&T for family plans, and it’s not particularly close.

T-Mobile vs. AT&T prepaid plans

T-Mobile wins this battle too.

Both AT&T and T-Mobile offer prepaid plans that cost a bit less than their postpaid plans, but T-Mobile, once again, offers way more value. Just look at the plan comparison above. Would you rather pay $40 a month for 10 GB of data with T-Mobile or $40 a month for 8 GB of data with AT&T? Imagine I’m a Southern Gentleman attorney as I snap my suspenders and say, “Your Honor, I rest my case.”

T-Mobile vs. AT&T coverage

AT&T wins the coverage battle.

Just when you thought AT&T was backed into a corner, it comes swinging back with significantly improved coverage. In the last few months, AT&T has upped its coverage game and is closing in on Verizon. Here’s how all the rankings break down for best coverage in the country:¹

• Verizon: 70% 4G Coverage
• AT&T: 68% 4G Coverage
• T-Mobile: 62% 4G Coverage

AT&T covers 68% of the country with its 4G network, while T-Mobile covers only 62% of the country with 4G coverage.¹ To be fair, a 6% difference isn’t massive, but it can make a big difference for folks in more rural parts of the country. Check out the coverage maps below and see how AT&T and T-Mobile cover your neck of the woods:

AT&T has the fastest download speeds too.

Along with the strong coverage, AT&T also has the fastest network for download speeds. Here’s how the data speeds breakdown for all four major networks:

AT&T leads the pack with download speeds of 27.5 Mbps, and T-Mobile falls to second place at 25.8 Mbps.² Download speeds make all the difference when you’re streaming videos, playing apps online, or scrolling through Instagram or Twitter. T-Mobile is no slouch when it comes to data speeds, but you should have the smoothest experience surfing the web with AT&T.

Recap: T-Mobile is cheaper but AT&T has better coverage.

It’s a close battle between T-Mobile and AT&T, but we have to give the championship belt to T-Mobile for its cheaper unlimited plans. AT&T does offer better coverage and download speeds, but its plans will cost you $5–$10 more every month. Even though we prefer T-Mobile over AT&T because of its cost, you might prefer the latter for its superior performance.

So, what do you value more—your monthly bill costing less or having a slightly better performance? Do you have any strong feelings about AT&T or T-Mobile? Let us know in the comments below.
