Xfinity Mobile Review: 10 Things to Know Before You Sign Up

  • What is Xfinity Mobile?: A low-cost cell phone service available to Comcast internet customers.
  • What network does Xfinity Mobile use?: Verizon’s network, plus access to millions of Xfinity Wi-Fi hotspots.
  • How much is Xfinity Mobile?: Shared data plans start at $12/month and $45/month for unlimited.
  • Does Xfinity Mobile allow Android phones?: BYOD has expanded to select Androids or buy a new one from Xfinity Mobile.
  • How good is Xfinity Mobile?: No major complaints after two years with Xfinity Mobile — read on for the pros and cons!

My cell phone bill got a lot cheaper after I made the switch to Comcast’s Xfinity Mobile, a low-cost wireless provider that uses Verizon’s network.

A few months after Xfinity Mobile quietly launched in 2017, I signed up for the affordable wireless plan and typically spent $12 a month before taxes and fees — $15 all in.

In this post, I’ll outline the top 10 things to know about Xfinity Mobile.

My review is different from some of the other Xfinity Mobile reviews you may find online because I’m not just a writer — I subscribed to the service for two years.

Read on to learn what you should know about Xfinity Mobile before you sign up…

1. Eligibility Requirement

Xfinity Mobile is unlike other mobile virtual network operators (MVNOs) because you must be an Xfinity internet customer to sign up for the service.

If you’ve had a lot of issues with Comcast cable or internet in the past, I can understand why you may not want to consider this service. I was willing to take the risk.

No Comcast in your area? Unfortunately, you’re not eligible for the mobile offer. Consider a service like Visible instead.

If you sign up for Xfinity Mobile and later cancel Xfinity internet because you move or for any other reason, you can continue to use Xfinity Mobile. However, there will be a $20/month per line fee added to your bill. Learn more here.

To be clear, that fee is not charged if you maintain Xfinity internet service. It’s only assessed if you later discontinue that service and want to keep Xfinity Mobile.

2. Plans and Pricing 

Verizon’s postpaid unlimited data plans cost between $70 and $90 for a single line of service. Xfinity Mobile uses Verizon’s towers and charges about half the price, but you won’t get special perks like the year of free Disney+ that Verizon is offering.

Xfinity Mobile features unlimited nationwide talk and text, no activation or line access fees on up to five lines and access to 19 million Wi-Fi hotspots.

Here are the new data plan options for Xfinity Mobile, which went into effect in August 2019:

  • Unlimited: $45/month per line and no monthly data usage limits (reduced speeds after 20GB)
  • By the Gig: 1GB =$12/mo, 3GB = $30/month and 10GB = $60/month; pay $12 per GB if you exceed your chosen amount

The $45/month Unlimited plan is per line, but the By the Gig plan is available for single lines or the data can be shared across all of the lines on your account. Taxes and fees are extra with all plans.

3. How I Paid $0 Per Month (Before Taxes and Fees)

Unfortunately, Xfinity Mobile has eliminated the 100MB of free data that it offered per month for new customers. The change went into effect with the launch of the new plans in August 2019.

Comcast says existing customers an keep their old plan and continue to get the 100MB of free data every month.

By connecting to Comcast’s Wi-Fi hotspots and monitoring my data through the Xfinity Mobile app, I was able to stay below that 100MB threshold for several months. My bill was $2 or $3.

Although the minimum new customers can pay is now $12 per month for 1GB of high-speed data, I wanted to point this out because using those Wi-Fi hotspots can significantly reduce your data consumption.

After I initially wrote my Xfinity Mobile review and uploaded my YouTube video, I’ve heard from dozens of people who switched from unlimited plans with their old providers and now pay less on the shared data plan with Xfinity Mobile. You just have to be willing to monitor your usage and connect to those Wi-Fi hotspots.

4. Flexible Data Plans: Unlimited vs. By the Gig

Here’s what I really like about Xfinity Mobiles service: Many other cell phone plans will offer 2GB or 5GB of data for a set price per month, use it or lose it. However, Xfinity Mobile gives you the option to pay for your data one gigabyte at a time.

For example, you can choose the 1GB plan and pay $12 per month. If you need a second GB of data, just pay another $12.

But if you need more data and the $30 for 3GB or $60 for 10GB plan becomes a better value, just switch. You can make changes to your plan during the middle of your billing cycle.

Of course, many people don’t want to worry about checking their data usage throughout the month. They may prefer the $45 a month unlimited plan.

My suggestion: Start with the By the Gig plan and see how it goes. You can always switch to the Unlimited plan if you end up using too much data. There are no penalties to switch back and forth between plans.

5. Xfinity Mobile vs. Verizon Data Dpeeds

One of the primary reasons that I left Sprint for Xfinity Mobile was for Verizon’s network, which RootMetrics consistently ranks as the best in the nation, followed by AT&T.

I’ve read stories about how Verizon may slow down data usage for its MVNOs, but that’s not my experience.

I downloaded the Speedtest by Ookla app and tested my Xfinity Mobile download speeds 10 times. Each time the download speed was between 40 Mbps and 70 Mbps — really fast!

In fact, that’s much higher than the speeds that Comcast says Xfinity Mobile customers should expect:

4G LTE network: typical download speeds of 5-12 Mbps and upload speeds of 2-5 Mbps

According to Verizon’s website, its 4G LTE wireless broadband is able to handle download speeds between 5 and 12 Mbps (Megabits per second) and upload speeds between 2 and 5 Mbps, with peak download speeds approaching 50 Mbps.

6. Mobile Hotspot 

Mobile hotspot is included with Xfinity Mobile at no additional charge. This allows you to get online by using your mobile data to create an internet connection.

For example, I tested this feature when I needed to use my computer while traveling in a place without Wi-Fi.

Xfinity Mobile’s website says you need to be on the By the Gig plan ($12 per GB) to get 4G LTE for hotspot-powered devices. Speeds are limited to 600 Kbps for those on the Unlimited plan.

  • By the Gig plan: 4G LTE mobile hotspot speeds
  • Unlimited plan: 600 Kbps mobile hotspot speeds

Translation: With the Unlimited option, you can still read email and browse the web, but there may be buffering when streaming video or music. There are no speed restrictions for the By the Gig plan.

I temporarily switched to the Unlimited plan to play around with the mobile hotspot feature and provide a better review of my Xfinity Mobile service.

Despite what Xfinity Mobile warns on its website, I was able to stream video without buffering and watched an entire show on my laptop that was powered by the mobile hotspot.

Although there are no additional charges for the mobile hotspot feature, the data that you use will count toward your data charges for the month if you’re on the By the Gig plan.

Learn more about setting up your personal mobile hotspot on Xfinity Mobile’s website.

7. Video Streaming

Some of Verizon’s postpaid unlimited plans allow for HD-quality streaming, but that’s not a guarantee with Xfinity Mobile.

As of August 2019, By the Gig defaults to HD resolution (720p for phones, 1080p for tablets) and Unlimited defaults to standard resolution (480p).

By the Gig users can turn on Data Saver to watch videos in standard definition, which requires less data. That’s what I would suggest.

Meanwhile, Unlimited plan users can add HD Pass to get 720p on phones and 1080p on tablets for $20 per month.

I streamed plenty of video on my smartphone while with Xfinity Mobile — things like Netflix, Hulu and YouTube — and I never had any problems with the video quality. Perhaps because a phone screen is so small that I couldn’t tell the difference between SD and HD.


Tip: To save money and still watch video in HD, you can always connect to Wi-Fi at home, work and whenever possible. Remember, the data you use over Wi-Fi doesn’t count against your plan’s data allowance.


8. Call and text performance

I had a great experience with Verizon’s network in the past, so I wasn’t really worried about Xfinity Mobile’s call and text performance where I live.

Since Xfinity Mobile runs on Verizon’s network, the coverage map looks a lot like the one for Verizon’s postpaid service. The difference is that Xfinity Mobile also has millions of Wi-Fi hotspots.

Take a look at the coverage maps below:

A great feature is that Xfinity Mobile supports Voice over LTE (VoLTE), which let me talk and use data at the same time. Wi-Fi calling has also been expanded to all but a few devices.

9. Phone Selection 

The latest iPhones and Samsung devices make up most of the 16 or so phones that Xfinity Mobile sells online and in its stores, but there are a couple of options for under $200.

Xfinity Mobile now allows you to bring select Androids to its network. They include the Samsung Galaxy S8 and S9. Unlocked iPhones are also compatible.

Samsung compatibility is significant because this is something Xfinity Mobile had been promising for a long time. Now, it’s finally here!

In addition to BYOD, you can purchase phones from Xfinity Mobile. Here’s a partial list of phones available for sale as of November 2019:

  • Apple iPhone 11
  • Apple iPhone 11 Pro
  • Apple iPhone 11 Pro Max
  • Google Pixel 4
  • Google Pixel 4 XL
  • Samsung Galaxy Note10+
  • Samsung Galaxy Note 10
  • Samsung Galaxy S10
  • Samsung Galaxy S10+
  • Apple iPhone XR
  • Apple iPhone XS
  • Apple iPhone XS Max
  • Samsung Galaxy Note9
  • Samsung Galaxy S9
  • Samsung Galaxy S9+
  • LG G8 ThinQ
  • LG Stylo 4 and 5
  • Motorola Moto E6

When I signed up for Xfinity Mobile in September 2017, I bought a Samsung Galaxy S8 online and it arrived two days later. Xfinity Mobile was offering $200 off new phones at the time.

If you don’t want to pay in full as I did, qualified customers can spread device payments over 24 months at 0% APR.

Speaking of phone deals, Xfinity Mobile has shifted to offering prepaid cards instead of cash discounts. There’s typically some type of phone sale going on for high-end devices like the Samsung Galaxy S10 or the Apple iPhone 11.

However, I’ve noticed that only one brand or the other (Samsung or Apple) is usually on sale at once. For example, there was a $250 prepaid card offer for the Samsung Galaxy S10 the last time I checked, but no iPhone discounts were available.

If there’s not a deal for the type of phone that you want, just wait a few weeks. The sales change frequently.

10. Customer Service

I set up my Xfinity Mobile service without ever visiting a store and didn’t have any problems getting started.

There are a number of FAQ pages that you can find within the app to answer questions about setting up service, switching data plans, billing and more.

You can also contact customer service via text, Facebook Messenger and phone — with an estimated wait time given. Xfinity Mobile’s customer service number is (888) 936-4968.

The first time I needed to contact Xfinity Mobile customer service was when my Samsung Galaxy S8 suddenly malfunctioned. I went to an Xfinity Store and couldn’t get an immediate replacement, but I was mailed a new phone the next day.

Since my phone was less than a year old and still under warranty, no additional money came out of my pocket.

The second time I called Xfinity Mobile was to ask whether my Samsung Galaxy S8 was locked or unlocked. Apparently, it was locked. Xfinity Mobile unlocked the device without a problem.

Final Thought 

I saved a lot of money during my two years with Xfinity Mobile! Although Visible and Total Wireless offer cell phone plans that run on Verizon’s network, Xfinity Mobile may be less expensive for light data users.

With a cheaper cell phone plan, you may expect to make compromises — not with Xfinity Mobile.

Pros Cons
Great value for By the Gig and Unlimited plansMust be an Xfinity internet customer
Verizon's top-rated wireless networkCan only bring select Androids to the service
Fast data speeds$20/month HD Pass for unlimited plan
Flexibility to switch data options
Phone customer service

My biggest fear about switching to Xfinity Mobile was that Comcast would take advantage of my loyalty and find a way to increase my internet bill — but that didn’t happen.

When my internet promo rate expired, I called Comcast’s customer retention department and they worked with me on the price. I ended up getting an extension of my $52 a month internet package for another year.

If you ever cancel Comcast internet service for a move or any other reason, you can keep Xfinity Mobile — but you may not want to. In that case, a $20 line access fee will be added to your bill. Learn more here.
