Believe it or not, you can find some surprisingly robust cell phone plans under $20. Sure, you won’t get unlimited high-speed data or tons of perks, but you can get unlimited calls, texts, and even a nice chunk of data for less than $20 a month. It’s kind of like getting into a fancy buffet, except you don’t pay for all the expensive wine.

We’ve narrowed down the four best cell phone plans under $20 that will give you the most bang for your buck.

Best cell phone plans under $20

Mint Mobile: Best value

Unlimited talk, text, and data
Pros
  • Only $15 a month
  • Solid network
  • Unlimited data
Cons
  • Deprioritization

What we like

It’s tough to find a cell phone plan that gets you unlimited talk, unlimited text, and unlimited data, let alone for so cheap. Mint Mobile hooks you up with all three things on T-Mobile’s reliable network and keeps your monthly bill to a tidy $15 a month.

Just $15 a month

Right now, all of Mint Mobile's phone plans are available for $15 a month for the first three months. And even after promo prices, Mint's 5GB and 10GB plans are only $15 and $20 a month respectively.

Mint Mobile is a mobile virtual network operator (MVNO) on the T-Mobile network. Translation: Mint Mobile uses T-Mobile’s network but charges way less than your typical T-Mobile cell phone plan. Think of it as the generic brand version of mobile wireless—the Kirkland of T-Mobile, if you will.

Now that we got all the jargon out of the way, let’s get to the good part. With the Mint Mobile Unlimited Data plan, you get all of this stuff for $15 a month:

  • Unlimited talk
  • Unlimited text
  • Unlimited data
  • 10GB mobile hotspot data

You can text and call as much as you want, and you still have plenty of data to use your GPS and check Instagram. 

What do I use data for?
Light Bulb

Most apps on your phone probably require data to function. Whether it’s Twitter, Instagram, or Clash Royale, you’ll need internet data to use them. Try to stick to Wi-Fi wherever you can to make that 3 GB of data last as long as possible every month.

Mint Mobile offers more data plans if you’d like to decrease your data allotment every month to save a few bucks. For example, you could choose Mint's 5GB plan or its 15GB plan.

Solid network

Mint Mobile uses T-Mobile’s network to offer wireless coverage, which just so happens to be the second-best coverage network in the country.1 As it stands right now, T-Mobile covers around 59% of the country and specializes in offering reliable coverage in more urban areas. Before you think about signing up for Mint Mobile, check your area in the map below and make sure it looks covered:

Mint Mobile/T-Mobile coverage map

Mint Mobile provides the same coverage to its customers with a caveat: deprioritization.

Fun fact: Ryan Reynolds owns Mint Mobile
Megaphone

Yes, that Ryan Reynolds owns Mint Mobile, the guy from Deadpool. At least you’ll have something to bring up if you ever bump into Ryan Reynolds.

What we don’t like

For all of Mint Mobile’s perks, it’s still an MVNO, which means deprioritization can mess up your day. No one likes their data speeds slowing down out of the blue.

Deprioritization

The catch with all MVNOs is that your data speeds can be deprioritized and throttled at any time. That's because the network your MVNO uses will prioritize its own customers over the MVNO customers. While it’s awesome to be on a bigger provider’s network and pay a fraction of the price, you still might have your speeds throttled.

Let’s say that you (a Mint Mobile user) and a friend (a T-Mobile user) attend a concert together. You take a rad video of yourself crowd-surfing, but your phone suddenly can’t get a signal strong enough to post the moment to your Instagram story. Meanwhile, your friend already posted the video of their crowd-surfing exploits.

You’d think that since Mint Mobile shares T-Mobile’s network, you would both enjoy the same coverage. Wrong! You were deprioritized on T-Mobile’s network so that your friend could have all the data to post their story. That’s so nice of you.

Deprioritization tends to rear its ugly head in more crowded and congested areas. Hopefully, it won’t be something that you experience too often, but deprioritization has a habit of showing up at the most inconvenient times.

Alternative value picks under $20

Here are some other wireless providers under $20 that give you a fairly balanced amount of data, calls, and texts.

Xfinity Mobile: Best bundle

If you've got Xfinity internet, you can cash in on Xfinity Mobile's cheap prices.
Pros
  • Cheap and flexible data plans
  • Reaches max coverage with Verizon network
Cons
  • Xfinity internet subscription required
  • Data deprioritization
Deals
Xfinity streaming + internet + mobile = big savings

One reason we call Xfinity the best cell service for bundling is because you can get unlimited gig-speed internet and streaming for just $50 per month when you add an Xfinity Mobile Unlimited plan.

Talk, text, stream, and surf the web from pretty much anywhere while saving money? That's our kind of deal.

This offer requires no term contract and comes with a 2-year rate guarantee.

What we like

Comcast Xfinity is well-known for its internet and TV service. And now it's a full house with Xfinity Mobile service.

The only catch is you need to be an Xfinity residential internet customer to sign up for Xfinity Mobile.

But if you've already got an Xfinity internet plan (or if you're considering signing up), you're ready to join this somewhat exclusive club that includes cheap cell phone plans that include 5G service.

Pay-as-you-go data

If you're not glued to your phone's screen for most of the day, chances are you don't need to pay for unlimited data. And that's where Xfinity's By the Gig plan shines.

It starts with 1 GB of data each month, and you simply pay for any extra data you use over that initial amount. Plus, Xfinity service comes with access to more than 18 million Wi-Fi hotspots across the US, so chances are you'll be able to hop on Wi-Fi instead of using your precious cellular data.

That said, if you use more than 3 GB of data in a month, we recommend the Xfinity Mobile unlimited plan instead. But both the Unlimited Data plan and the By the Gig plan come at fantastically cheap prices.

Exceptional coverage

Xfinity Mobile uses Verizon's cell towers to connect your calls and Clash of Clans gaming sessions. That's a huge perk, since Verizon tops the charts for widest 4G network coverage across the country.

There is a caveat, though: Verizon is lagging behind T-Mobile and AT&T in terms of 5G coverage. So if you've got a 5G device, Xfinity Mobile's coverage might not bump your signal up to the coveted 5G icon at this time.

Xfinity Mobile/Verizon coverage map

You'll see the same coverage with Xfinity Mobile plans as you would with a Verizon Wireless plan.

The major things to watch out for with Xfinity Mobile are deprioritization and data speed throttling.

What we don’t like

Just like most MVNOs that use one of the big three networks, your Xfinity Mobile service could suffer from deprioritization and data speed throttling. 

That means slow speeds could be in store.

Deprioritization

Because Xfinity Mobile uses Verizon's network, its service could be deprioritized, meaning folks who signed up directly with Verizon Wireless get priority speeds over you and other MVNO customers.

Thankfully, deprioritization doesn't tend to be an issue unless you're sitting in a crowded area and using your cell phone to hurl disgruntled birds at snarky pigs. But that doesn't mean data deprioritization won't show up like an uninvited guest.

Alternative mobile bundle pick under $20

If you're looking to save some cash by bundling your cell phone service, Spectrum Mobile is another option.

US Mobile: Best unlimited talk, text, and no data plan

Unlimited talk and text on the best network
Pros
  • Best coverage network
  • Unlimited talk and text
Cons
  • Less data

What we like

If you know you just want unlimited talk and unlimited text without any data, you’ll get the most value out of US Mobile. US Mobile used to offer a zero-data plan, but now they've added a $5 plan with 500 minutes and 500MB of data, as well as a $10 plan with 2GB of data and unlimited talk and text. We recommend the $10 plan, since most mobile users need unlimited texts. 

With the 2GB Shared Data Plan, you get on Verizon’s network and 2GB of data for $10 a month, which means you can make calls and get texts out from basically anywhere, plus enough data to access your movie tickets from your phone or scroll Facebook at the DMV.

Best 4G coverage network

For those of you who can live without monthly data (honestly, good for you) but still want unlimited talk and text, we recommend getting on the best network. US Mobile is an MVNO that operates on the Verizon network—by far the most reliable 4G network in the country. Mint and Tello use T-Mobile's network, which comes in first with the best 5G coverage. Here’s how the rankings break down for best coverage in the country, if you’re curious:

Best 4G coverage

  1. Verizon: 70% 4G coverage
  2. AT&T: 68% 4G coverage
  3. T-Mobile: 62% 4G coverage

Best 5G coverage: 

  1. T-Mobile: 41% 5G coverage
  2. AT&T: 18% 5G coverage
  3. Verizon: 11% 5G coverage

Verizon offers 8% more 4G coverage than third-place T-Mobile. This network really shines in more rural areas, so if you’re an avid camper, you can count on getting calls and texts whilst in the wilderness.

Do I still need to worry about deprioritization?
Pin

Since US Mobile is indeed an MVNO, you’ll still be subject to deprioritization. You’ll get the best coverage possible for a plan under $20 with US Mobile, but your signal could still drop in more crowded areas.

Check out the coverage map below to see what we’re talking about:

US Mobile/Verizon coverage map

Unlimited talk and text

You need not worry about going over your limits for calls or texts—you get unlimited talk and text for your $10 a month. US Mobile makes perfect sense for folks who know they just want to make calls and texts and not use any mobile data. You can call and text to your heart’s content and not worry about any extra charges.

What we don’t like

You won’t be able to check Instagram, download apps, or online shop without a Wi-Fi signal. Maybe that’s a good thing for some of us, but if I didn’t have my GPS app, I would get lost going to the grocery store.

No online mobile data

This US Mobile plan doesn’t come with a single ounce of data, so you won’t get much use out of a smartphone. Most apps, like GPS, online shopping, social media, and online gaming, require mobile data to work at all. You’ll need to live life in the good ol’ days before mobile data when we used stuff like Mapquest.

Get free mobile data with Wi-Fi
Light Bulb

If you do have a smartphone, you can always hop on a Wi-Fi network to get your data fix. There are probably plenty of free Wi-Fi spots around your town that you can use. You can usually find free Wi-Fi at bookstores, cafés, and libraries.

Alternative unlimited text, unlimited call, and no data plans

You can find even cheaper mobile plans with unlimited talk and text, but they won’t be on the Verizon network. But if you live in a city with generally reliable coverage, you can get away with one of the plans below:

Tello: Best data plan under $20

Get the most data you can under $20.
Pros
  • 10GB of data every month
  • No overage charge
Cons
  • Risk of data throttling

What we like

This plan from Tello was the most high-speed data we could find for under $20 a month. You won’t find a better price for 10GB of data every month.

10 GB of data every month

For those of you who want as much data as possible and still pay below $20 a month, Tello's $19 plan is your best option. You get 10GB of high-speed data a month with this plan, which means you can do a lot more streaming, posting on social media, and online gaming on the go.

Will 10GB of data be enough for me?
Pin

You can think about gigabytes of data in these terms—every hour of HD streaming you do on Netflix will cost about 1 GB of data. You can do the equivalent of 9 hours of HD streaming every month with your wireless connection. We would also recommend checking your current data usage to get a better idea of how much data you use.

No overage charges

Even if you pass your 10GB of high-speed data threshold, you won’t be charged any overages with Tello. Instead, your data will slow down dramatically to the point where you can’t really do anything on the internet, but hey, at least you won’t owe any extra money.

In a sense, you have unlimited data with Tello, but you only have a certain amount of high-speed data. Don’t plan on being able to comfortably use your GPS app or scroll through Instagram after you pass that 10GB of high-speed data, but you should be able to open up a web page with some patience. Remember, you can always use Wi-Fi to save your high-speed data.

What we don’t like

Tello used to operate on Sprint's 4G LTE network, but now runs on T-Mobile's 4G LTE and 5G nationwide network which gives you better coverage than you used to get. But because Tello is an MVNO, you still have the risk of having your data throttled.

Data throttling

As is the case with every small prepaid carrier, your may experience data throttling from time to time. Tello uses T-Mobile to provide network coverage, but during peak-usage periods, T-Mobile gives priority data to its own customers.

For example, you may notice that your data speeds grind to a halt during your commute home from work. This can happen because tons of other people are doing the same thing you are: streaming Spotify while driving home. As a Tello user, you sadly get last dibs of T-Mobile data when things get congested.

Tello/T-Mobile coverage map

Alternative data plans under $20

You won’t find any carriers that give you more than 5 GB of data for under $20 a month, but there are plenty of providers that will give you 3 GB of data for a similar price with a better network.

Recap: What are the best cell phone plans under $20?

There are a surprising number of cell phone plans that cost less than $20 a month. But if you want to keep your monthly cell phone bill that cheap, expect to make some sacrifices. You won’t have unlimited high-speed data or tons of perks, but you’ll certainly save some money every month with these cell phone plans.

  • Best value plan: Mint Mobile offers 5GB of data and unlimited talk and text on a reliable network. Somehow it all costs $15. What's even more unbelievable, all of Mint's plans are available for $15 a month for the first three months, including its unlimited data plan. All that value easily makes it our top recommendation for a cell phone plan under $20.
  • Best mobile bundle: Xfinity Mobile requires you to have an Xfinity internet plan, sure. But it offers cheap plans that run on Verizon's extensive network in return.
  • Best unlimited talk and text plan: US Mobile offers a super affordable unlimited talk and text plan on the best wireless network. You should have no problem getting calls and texts out wherever you roam.
  • Best data plan under $20: Tello mobile hooks you up with 10GB of data every month for under $20, plus 10GB of mobile hotspot data. You won’t find a plan that beats 10GB of data and hotspot data at that price.
