Mint Mobile is a new cell phone carrier taking the market by storm. Xfinity is a giant in the industry known for its internet, television, and home security services. Which company has the best cell phone plan for you?

The short answer is this: Mint Mobile’s low-priced plans beat Xfinity’s at every level. That—plus the fact that Xfinity’s service is limited to existing customers—make Mint the better choice for most people.

But some existing Xfinity customers might like the flexibility of Xfinity’s By the Gig plans. Also, Mint doesn't offer any family plans, whereas Xfinity does.

We’ll go over all the details you need to know in this review. But first, let’s go over a few tips for how to choose the ideal phone plan.

How to choose a cell phone plan

We’ve written hundreds of these reviews, and we’ve learned a thing or two about evaluating plans. Here are some features that you’ll want to make sure you look at before you make your choice.

  • Data: Knowing how much data you need is key to choosing the right plan. Keep in mind that not all data comes at the same speed. Some plans will be subject to data throttling and deprioritization.
  • Price: There are more cellular carriers than many people realize, and some of them offer wildly cheap plans. Be sure that you compare prices between multiple carriers before signing up for a plan.
  • Coverage: There are three major networks in the country. Check coverage maps to figure out which one has the best coverage in your area.
  • Features: There are tons of features and perks—like hotspot data, international benefits, and HD video streaming—that don’t come standard on every plan.

Mint Mobile vs. Xfinity Mobile plans and pricing

Mint’s prices are slightly lower than Xfinity’s at every level

Mint and Xfinity Mobile both offer a good spread of lower-data plans as well as unlimited talk, text, and data options. Mint’s prices tend to be better, but some people may like Xfinity’s By the Gig option. We’ll go over the two carriers’ plans in detail, beginning with Mint.

Mint Mobile’s data plans

Mint Mobile has four plans to choose from. Every one of these plans comes with the following:

  • Unlimited talk and text
  • 5G network access
  • Mobile hotspot data
  • T-Mobile coverage

The only major difference between each plan is the cost and the amount of data you get. Take a look.

Mint Mobile’s plans

With the three limited data options, you’ll get 4 GB, 10 GB, or 15 GB of 4G LTE data. After you reach your data limit, your speeds will be reduced to 128 Kbps, which is very slow (you won’t be able to stream video or audio reliably with those speeds).

So what about Mint’s “unlimited” data option? Well, we put the word unlimited in scare quotes for a reason. It’s more like a 35 GB plan because after you use that much data your speeds will go way down. While 35 GB is a lot of data, it’s hardly unlimited.

One more thing to note about Mint’s plans is that they are all subject to data deprioritization. This means that customers are always at risk of having their data slowed down when the network is busy even before reaching their data cap. (This is also true for Xfinity’s plans.)

In short: Mint’s plans are an awesome deal if all you need is 4–35 GB of high-speed data, and you don’t mind the risk of occasional data slowdowns due to deprioritization. But if you need truly unlimited data or the very fastest data speeds, then you might want to look elsewhere.

A note about Mint’s prices

Mint definitely offers some of the best cheap plans around, but be sure to read the fine print before you sign up. Most of the prices that Mint advertises are introductory, and they can increase after the first month of service.

For example, the company’s 15 GB plan goes from $25 to $45 after the first month. If you want to keep the $25 a month price, you have to sign up for another 12 months of service. Take a look at this screenshot from Mint’s site.

In short, Mint’s best deals are only available to those who are willing to sign up for the long haul.

Xfinity Mobile’s plans

If you’re an existing Comcast-Xfinity home internet or cable customer, then you’re eligible to hop on an Xfinity Mobile plan. If you’re not, then you’re out of luck (but don’t sweat it, Mint is probably a better choice anyways). Here are the plans that Xfinity Mobile sells.

Xfinity Mobile's plans

You can split Xfinity Mobile’s plans into two main categories: By the Gig and Unlimited Data.

The By the Gig plans start at just $15. That gets you unlimited talk and text, and 1 GB of data. Plus, you’ll get free access to millions of Xfinity-operated Wi-Fi hotspots throughout the country.

You can go up to the 3 GB or 10 GB plans if you think you’ll use more data. On any By the Gig plan you’ll be charged an extra $15 for every GB of data you use beyond the original allotment. That can add up fast, so if you use a lot of data, then the Unlimited option may be a better choice.

Xfinity Mobile’s Unlimited Data plan will get you unlimited talk, text, and data, plus 5G access and hotspot data. But your download speeds will be throttled at 5–12 Mbps (check out T-Mobile for unthrottled speeds), and your data will be capped at 20 GB (so much for unlimited). After you hit that cap, your speeds can be reduced even more.

The bottom line on Mint vs. Xfinity plans

To summarize, Mint’s limited-data plans offer more data for less money. Neither company offers an amazing unlimited data plan (for that, check out Visible, AT&T, or Verizon), but Mint’s plan is probably a slightly better deal because its data cap is higher. We hate to say it, but Xfinity doesn’t really offer any clear advantages over Mint.

Mint vs. Xfinity family cell phone plans

Winner: Xfinity Mobile costs less when you add more lines

Getting a family plan is one of the best ways to get more bang for your buck. Unfortunately, only Xfinity offers savings in the family plan department. Here’s what you need to know.

Mint Mobile’s family plans

You can have up to five lines on a single Mint Mobile account. This allows one person (the primary account holder) to make payments and changes to each line. But that’s really the only benefit of getting a family plan. Mint doesn’t offer any discounts or extra perks for those who add lines.

Xfinity Mobile's family plans

Xfinity Mobile offers great multi-line savings with their unlimited data plans.

  • 1 line — $45/mo.
  • 2 lines — $80/mo. (or $40 per line)
  • 3 lines — $100/mo. (or $33.33 per line)
  • 4 lines — $120/mo. (or $30 per line)

As you can see, with Xfinity Mobile's family plans with unlimited data, you get a much better deal than you would with Mint's "no family plans" approach.

Mint vs. Xfinity coverage

Mint’s network has faster data speeds, but Xfinity’s wins when it comes to coverage

Both Mint and Xfinity are mobile virtual network operators (MVNOs), which means that instead of operating their own cellular networks, they lease bandwidth from other, larger companies. In this case, Mint uses T-Mobile’s network, and Xfinity uses Verizon’s.

There are benefits to both of these networks. T-Mobile’s network has the largest 5G infrastructure in the country and the fastest 4G speeds. So if you want speed, Mint is the way to go. Meanwhile, Xfinity’s Verizon-run network has the best nationwide coverage.

Here’s a look at the two network’s coverage maps.

Mint vs. Xfinity phones and devices

Both carriers offer the main flagship devices

The best time to get an awesome deal on a new phone is when you’re signing up for a new plan. Mint and Xfinity both offer some sweet deals on the newest flagship devices, like the iPhone 12. Take a look at some of the best-selling phones from each company.

Recap: Which carrier is right for you?

That’s it for our in-depth analysis of Mint and Xfinity. But we like to do a quick recap before we say goodbye. Here’s the short version of everything we said above:

  • Plans: Mint and Xfinity’s plans look pretty similar from afar. But a close look reveals that Mint’s plans offer more bang for your buck at every level. Unfortunately, neither carrier offers an amazing unlimited data plan.
  • Family plans: You can add extra lines to your account with both Mint and Xfinity. However, you won’t see any family plan price discounts unless you go with Xfinity.
  • Coverage and performance: Both Mint and Xfinity have issues with data throttling and deprioritization. Mint’s T-Mobile-run network can theoretically offer better data speeds, but Xfinity’s Verizon-run network gives you more nationwide coverage.

We hope that this Mint vs. Xfinity review helped you find the perfect plan!
