Xfinity Mobile is a cell phone service offered by Xfinity.

It’s available for current Xfinity Internet, TV, or phone customers, and it may actually be a surprisingly better option than you might think. 

I’ve been using Xfinity Mobile for the past two months now, and in this review I’m covering everything you need to know about it.

Xfinity Mobile Cell Phone Plans

Xfinity Mobile has two types of plans to choose from: by the gig and unlimited. 

By-The-Gig Plans

Let’s start with the by-the-gig plans. There are three options here: 

Xfinity Mobile by the gig plans
By The Gig Plans

On the surface these plans may seem expensive, especially the $60 plan with only 10GB of data.

The secret to how these are actually super affordable? You can share the data with up to 10 lines on your account at no extra cost.

Any by-the-gig plan can share data with up to 10 lines at no additional charge

For example, a family of four could opt for the $60 10GB plan and share the data between all the lines. 

example of the $60 10GB plan split between four lines
A family of four could pay just $15 per line with Xfinity Mobile's 10GB shared data plan

Each person could use the same amount of data, about 2.5GB each, or they could use different amounts that add up to 10GB. 

Either way, the cost per line comes out to just $15/month, which is a great deal for a family of four.

The by-the-gig plans support HD video streaming, mobile hotspot, and all the standard features you’d expect like visual voicemail, Wi-Fi calling, VoLTE, and 5G access.

The by-the-gig plans are great options for lighter data users and families looking for something affordable.

But, there is one downside: data overage charges. 

If you go over your included data amount, Xfinity Mobile charges you $15 for each additional GB rounding up. 

So if you’re on the 1GB plan and use 1.2GB of data, then you’ll be billed $30 total instead of the usual $15. 

Thankfully you change plans to the Unlimited Plan at any time during your billing cycle, even on the very last day, and you will NOT receive any data overage charges. So while data overages are something to know about, they can easily be avoided by switching to the Unlimited Plan with just a couple of taps in the Xfinity Mobile application.

Xfinity Mobile data overages
You're automatically charged data overages at a rate of $15 per GB, rounding up. That means if you go over 1GB on the 1GB plan, you'll end up paying $30

There are also five easy ways to manage and reduce your data usage:

1. Data Usage Alerts

Xfinity Mobile sends you text and email alerts when you’re getting close to your limit. These are helpful for monitoring your usage.

2. Turn Off Cellular Data

You can always turn your cellular data off at any time on your device itself. 

This will prevent any additional usage if you’re getting close to your limit. 

Android users also have the additional luxury to set data usage alerts to get notified when you reach a certain threshold.

You can turn off your cellular data at any time from within your phone's settings app to stop any additional data usage
Android users can configure their phones to warn them when they have hit a certain data threshold and shut off data automatically at a certain limit

3. Free Access to 19 Million Xfinity Wi-Fi Hotspots

Xfinity includes free access to their over 19 million Xfinity WiFi hotspots nationwide. 

Your phone will automatically connect to an Xfinity WiFi hotspot when it’s nearby, and you get unlimited usage on hotspots that doesn’t count against your data allotment. 

More on these hotspots later.

4. Turn On Data Saver

Data Saver is a feature that limits your video streaming speeds to 1.5Mbps. This can stream up to 480p standard definition videos and it helps reduce your data usage.

5. Upgrade To The Unlimited Plan

You can always upgrade your by-the-gig plan to the unlimited plan at any time. 

The unlimited plan is $45/month and has no overages so you know your max bill will be $45. 

Plus, you can actually manage each line individually. 

If there is one person who is using a lot of data, then you can switch them to unlimited while keeping the rest of your lines on the shared by-the-gig plan. 

Just make sure you upgrade to the unlimited plan before you incur any overage charges. 

The Xfinity Mobile rep I spoke with said once you incur an overage charge, you’ll have to pay it even if you end up switching. 

That brings us to Xfinity Mobile’s unlimited plan.

Xfinity Mobile Unlimited Plan

Xfinity Mobile’s unlimited plan is $45 per month. It includes unlimited handset data and unlimited hotspot data. 

But, this plan isn’t actually unlimited

There are three key caveats:

  1. Smartphone data is limited to 20GB at high speeds. After 20GB, you’ll be slowed to 1.5Mbps download and 750Kbps upload. 
  2. Hotspot data is capped at 600Kbps. That’s good enough for some light email use, some light social media, and if you really wanted to you could stream YouTube videos at standard definition. The bottom line here is that the hotspot data is slow. Not ideal.
  3. Video streaming quality is limited to 720p. Video streams at 4Mbps max speed.
Xfinity Mobile unlimited plan caveats
Xfinity Mobile's unlimited plan isn't actually unlimited. It has three key caveats.

Except, you actually can get 4K video streaming at certain locations. 

(What? Location-based video streaming quality? Yes, more on that when I talk about coverage & data speeds).

Still, 20GB of high-speed data is PLENTY for a majority of consumers. 

According to Ericsson’s Mobility Report, average data use in North America is just 14.6GB.

That means something like 80-90% of you reading this right now would be perfectly fine on Xfinity Mobile’s unlimited plan with 20GB of high-speed data.

You would never notice any slowdowns or drops in performance.

And at $45 per month, it’s WAY cheaper than the $70+ unlimited plans Verizon is offering directly.

Plus, let’s not forget Xfinity’s family discounts. 

A family of four can get unlimited data for $30 per line, which is less than the $35-$45 per line unlimited plans from Verizon, AT&T, or T-Mobile. 

You’d save an estimated $720 per year by going with Xfinity Mobile.

Xfinity Mobile can save customers upwards of $720 per year compared to plans from Verizon, T-Mobile, or AT&T

Another perk is you get access to Xfinity’s WiFi hotspots. 

This means when you’re at places like your gym, your favorite coffee shop, or your favorite restaurant, or any of the other 19 million places with hotspots (that you can easily find with the Xfinity Hotspot app), you get unlimited free Wi-Fi that doesn’t count against your high speed data usage.

Wi-Fi speeds are at 25Mbps down and 5Mbps up, which is fast enough to stream 4K TV shows and movies.

You can even connect to the hotspots on your other devices like your laptop and tablet, making them great for staying connected while traveling and working from your favorite coffee shops.

Xfinity Mobile Coverage

Okay, now let’s talk coverage, data speeds, and why you can only stream 4K video in certain locations. 

Xfinity Mobile uses Verizon's LTE and 5G networks for coverage. Anywhere you have Verizon coverage, you’ll have Xfinity Mobile coverage.

Xfinity Mobile Data Speeds

Data speeds are exactly the same between Xfinity and Verizon, too. 

This is because Xfinity Mobile gets priority data. 

Priority data is typically only reserved for postpaid subscribers on Verizon (those paying $80+ on their cell phone plan), but Xfinity Mobile customers get access to it, too.

Priority data basically gives you slightly faster speeds when the network is busy, such as at sports games, stadiums, and airports. 

Xfinity Mobile vs Verizon speed test
Xfinity Mobile customers will enjoy the exact same data speeds and performance as postpaid Verizon customers thanks to also having priority data

People who are on prepaid plans, which are deprioritized, will notice slower speeds in crowded areas. 

Verizon vs Visible vs US Mobile data speed test
Verizon priority data speeds are about 2x to 3x faster than the deprioritized data speeds on Visible and US Mobile (Only when tests are run at the same time though. When run separaetly, all plans get the same full speeds available, which were about 50Mbps at my location)

Xfinity Mobile includes priority data in the by-the-gig plans for all devices and on their unlimited plan for 5G devices. 

The only exception is LTE devices on the unlimited plan, which are deprioritized. 

Customers with LTE devices on unlimited can choose to get the $20 HD Pass, which enables “higher quality cellular service during times with high network traffic,” aka priority data, and HD video streaming. 

The HD Pass is NOT available if you’re using a 5G device.

How To Stream HD Video on Xfinity Mobile

And that then begs the question: how do you stream HD video on the unlimited plan with a 5G phone, and why is it only at specific locations?

Well, I’ll tell you how: by connecting to Verizon’s Ultra Wideband 5G network. 

Xfinity Mobile gets full access to the Ultra Wideband 5G network, and all devices connected to Ultra Wideband get truly unlimited data, unlimited hotspot data, and 4K video streaming. 

I got over 3.5Gbps down on my Xfinity Mobile line at Sloan’s Lake Park here in Denver, Colorado. 

Xfinity Mobile Ultra Wideband 5G speed test
I hit peak download speeds over 4Gbps on my Xfinity Mobile line while connected to Verizon's Ultra Wideband 5G network here in Colorado

Hotspot speeds reached over 400Mbps. 

Xfinity Mobile hotspot speeds on ultra wideband 5G
Say goodbye to the 600Kbps hotspot cap. When connected to Ultra Wideband 5G, you get unlimited hotspot data at full speeds. I tested and got over 450Mbps in my area.

And when I tested with, a test that connects to Netflix’s video servers to measure video streaming speeds, I got over 1Gbps, which is fast enough to stream 40 4K movies at the same time. 

Data use on Ultra Wideband also doesn’t appear to count against your high-speed allotment, either. I used over 28GB and am still getting fast speeds. 

Two problems here though:

  1. There is no way to separate Ultra Wideband 5G use from regular use that counts against your high-speed limit. My app says I’ve used 28GB, but I have no idea how much of that counts against my high-speed limit.
  2. Verizon Ultra Wideband 5G covers like 0.1% of the population. Sure, it is continuing to expand, and its coverage could improve dramatically once C-Band spectrum is officially launched, but until then you're probably going to be stuck with the 20GB at high-speeds and the hotspot data at 600Kbps. 

Xfinity Mobile Application

Now let’s quickly talk about the mobile application. Xfinity does provide an app for managing your account. 

Xfinity Mobile app
Xfinity Mobile's app easily lets you manage your account preferences and get support

You can use the app to:

  • See active lines and remaining days of service
  • See data usage
  • Switch plans
  • Purchase international add-ons
  • View your current and historical bills
  • Upgrade your device
  • Report your device lost, damaged, or stolen
  • Suspend or cancel your service
  • Add lines to your account
  • Get support

The Xfinity Mobile application has a clean design and gives you the information and tools you need at your fingertips. 

I especially liked how you could easily switch plans right from the app, and how you got a detailed breakdown of your data usage each month.

Xfinity Mobile Customer Service & Support

How is customer support on Xfinity Mobile?

Xfinity Mobile actually ranked #1 in the 2019-2020 American Customer Satisfaction Index (ACSI®)* 

But, what is support actually like?

Customer support is available via chat on the app or online, or via phone. 

The chat presents a bunch of automated options, and I disliked how it sent me in circles trying to answer specific topics instead of connecting me directly to a rep.

Thankfully, if you ask for a rep you are typically able to request a callback or message someone directly in chat.

I found the callback feature worked best for me.

I was typically called within a couple of minutes and connected to a rep in about 5 minutes or less. The reps were able to answer my questions about the service.

For me, I thought customer service was generally good.

I think Comcast knew their internet was notorious for providing poor customer service, so they wanted to do something different with Xfinity Mobile.

Is Xfinity Mobile Worth It?

So at the end of the day, is Xfinity Mobile worth it? How does it compare to the competition, and is it worth signing up for?

Xfinity Mobile vs. US Mobile

Compared to US Mobile, which also uses the Verizon network for coverage, Xfinity Mobile’s plans are more expensive and include less data. 

$15 gets you 5GB of data on US Mobile compared to just 1GB on Xfinity Mobile.

BUT, you have to keep in mind that Xfinity Mobile includes priority data, which will offer a better experience during times when the network is busy, and they have more features like Wi-Fi calling.

US Mobile offers more affordable plans that also include more data

Xfinity Mobile vs. Visible

In terms of unlimited plans, I think Xfinity Mobile compares well. 

It costs less than Verizon’s cheapest unlimited plan and includes basically the same features. 

Compared to US Mobile and Visible though, it’s a tougher choice. 

US Mobile includes more high-speed handset data at 75GB, and Visible’s hotspot data is truly unlimited and over 8x faster at 5Mbps. 

Still, I think Xfinity Mobile’s 20GB of priority data will provide a better experience for most people than being deprioritized on either US Mobile or Visible.

You have to remember you’re also getting access to Xfinity’s Wi-Fi hotspots on Xfinity Mobile, and the multi-line discount makes Xfinity Mobile even more competitively priced.

Xfinity Mobile Discounts

Xfinity will also throw in up to a $30/month discount on your internet plan when you sign up for Xfinity Mobile. That makes the net cost of ownership for Xfinity Mobile drops down by a LOT.

Finally, Xfinity Mobile is also offering great discounts on devices for new customers. 

You can currently get:

  • $200 off a new iPhone 13, iPhone 13 Pro, or Galaxy S21 with no trade-in required
  • $200 prepaid card when you bring your own device
  • A free Motorola 5G Ace

Should You Switch to Xfinity Mobile?

At the end of the day, I think Xfinity Mobile can be a great, affordable option for a LOT of people. 

The multi-line discount makes Xfinity Mobile competitively priced, it comes packed with full-featured service, and it offers a premium network experience with priority data.

And, unlike Comcast, Xfinity Mobile is actually known for having decent customer service. 

You can check out their current deals and sign up for service here.


Three quick things I wanted to mention that didn’t make their way into the review:

  1. Billing is completely separate from Xfinity Internet and Xfinity Mobile. It’s like you’re signing up with an entirely new company. 
  2. Xfinity Mobile is also postpaid, so you’ll be issued your bill midway through your next billing cycle.
  3. If you purchase a device from Xfinity Mobile, it will be locked to Xfinity Mobile. To get it unlocked, your device must be paid off in full, and it must have been active on the network for at least 60 days.
