Xfinity Mobile Review: From a Customer (Updated for 2021)

This Xfinity Mobile review has been updated for 2021. Long-time readers may be quite surprised to find this Xfinity Mobile Review on this site. Given my extensive collection of diatribes against Xfinity (Comcast) in recent years, I’m as surprised as you are.


  1. I’ve previously and extensively reviewed the cheapest data plans, cheapest prepaid plans, and cheapest mobile WiFi hotspot plans on the market, and I’ve come to the conclusion that, at this moment, Xfinity Mobile may be one of the most compelling budget offerings of them all – and can potentially save you some serious money.
  2. Despite my prior grievances with Xfinity Mobile’s parent company, Comcast, I have been an actual Xfinity Mobile customer – we have tested Xfinity Mobile on one of our mobile devices for many months.
  3. Xfinity is not holding me hostage. Nor did they compensate me to write this review.

So let’s jump right in. Here’s what you’ll find in this Xfinity Mobile review:

What is Xfinity Mobile?

Xfinity Mobile is a newer mobile service from ISP/Cable TV conglomerate, Comcast Xfinity. It somewhat quietly launched to customers in May of 2017, and was live in all Xfinity markets in August, 2017.

In addition to 5G and nation-wide 4G LTE coverage (on Verizon’s network), Xfinity Mobile also boasts 18 million+ WiFi hotspots, and flexible low-cost plans.

Can I Get Xfinity Mobile? Xfinity Mobile Availability

In order to become an Xfinity Mobile customer, you must first be a residential Xfinity Internet service customer, residing within Xfinity’s market map.

If you’re unsure about Xfinity availability, you can check if Xfinity internet service is available in your area here. If it is, and you’re an Internet service customer, you can get Xfinity Mobile.

What Network Does Xfinity Mobile Use?

Xfinity Mobile is a mobile virtual network operator, or MVNO. As an MVNO, Xfinity Mobile doesn’t own its own wireless spectrum, it buys wholesale priced access from one of the 3 big wireless spectrum owners in the United States.

Xfinity Mobile runs on Verizon’s Network. Making a call? You’re calling on Verizon’s network. Using mobile data? Verizon’s network. You’re basically getting all of the touted benefits of Verizon’s network at a fraction of Verizon prices.

Xfinity Mobile Coverage Map

Xfinity Mobile, by virtue of running on Verizon’s Network, has access to 5G in select locations and the largest 4G LTE network in the US. Verizon touts that it covers 327 million people, 99% of the country’s population, and more square miles than any other network. Here is an interactive coverage map.

Xfinity WiFi Hotspot Map

In addition to offering up Verizon’s Network for prices that are much cheaper than Verizon (more on that in a bit), Xfinity Mobile sets itself apart from the competition in that you can tap in to over 18 million WiFi hotspots. Xfinity makes this possible through using modems it leases to customers as WiFi hotspots. Devilishly clever.

This can allow you to keep your mobile data usage to a minimum, if you’re able to find a hotspot to connect to. Here is an Xfinity WiFi hotspot map or you can use the Xfinity app, which can be used offline.

Xfinity Mobile Plans & Prices

Xfinity Mobile plan costs are low and flexible. Certainly lower than any of the big 3 carriers, but lower than even most of the cheapest of bare-bones MVNOs (who often have close to zero customer service).

For starters, everyone gets:

  • Unlimited nationwide talk and text, at no added charge
  • Up to 10 lines included
  • Free access to the 18 million+ WiFi hotspots

Additionally, Xfinity Mobile offers international roaming coverage (for a price).

Beyond talk, text, & WiFi – if needed (and I plan to only need it if on an extended trip), you have a choice of data plan options:

  • By the gig (3 options): $1 GB for $15, 3 GB for $30, or 10 GB for $60. Data can be shared on up to 10 lines. No rollover.
  • Unlimited: $45/line/month (after 20 GB of monthly data use, speeds are reduced to a maximum of 1.5Mbps download/750 Kbps upload). Note: this is the lowest price I’ve seen for that much 5G.

You can switch from “by the gig” to an “unlimited” plan within the same month or from “unlimited” to “by the gig” at the start of the next billing cycle. You can find lower price per GB data plans out there, but you typically have to pay for talk and text with those plans, which would wipe out the benefit.

The Xfinity Mobile app (Android here, iPhone here) shows you where your data usage is each month, in order to keep your data usage in check.

Does Xfinity Mobile Have Contracts?

No. There are no contracts with Xfinity Mobile. You can leave at any time, if you’re not happy, without penalty or early termination fee. However, you may have to pay off the remaining balance on your phone and plans (which is fair).

Can you Use Xfinity Mobile as a Personal Hotspot?

You can use Xfinity Mobile data to create a personal WiFi hotspot. According to Xfinity Mobile:

If you have the Unlimited data option, speeds on any connected device will not exceed 600 Kbps. At that speed, you’ll be able to perform common tasks such as email, instant messaging, and basic web browsing. However, you’ll likely experience buffering when streaming audio and/or video on your connected devices.

If you prefer 4G LTE for your hotspot-powered devices, go for By the Gig. Personal hotspot speeds are not automatically limited with this data option, but you can still use Data Saver to dial down your data speed and help manage your costs.

There are no additional fees for using your phone as a hotspot, and you can do it whether you have By the Gig or Unlimited. Data used as a mobile hotspot will count toward your data charges for the billing cycle. Remember, your laptop may consume more data than your phone would for similar activities.

If you Cancel Xfinity Internet Service, Can you Keep Using Xfinity Mobile?

Yes, you can keep using Xfinity Mobile if you cancel Xfinity Internet. A $25 per line monthly charge applies if at least one of the following post-pay subscriptions are not maintained on the account: Xfinity TV, Internet or Voice service.

Xfinity Mobile Phones

Xfinity Mobile has a solid offering of mobile devices (mostly on the higher end), including both iPhones and Androids. You can either buy the phone outright or spread out the cost of the phone over 24 months (at 0% APR).

Xfinity Mobile BYOD (Bring Your Own Device)

There was no Xfinity Mobile option to bring your own device (BYOD) until recently, but now you can bring your own iPhone device (iPhone 6 and later for iPhones, and Galaxy S8 or later for Android). You can check device compatibility here.

If you bring your own device, there are no added fees, and you can get a free SIM card. And yes, you can still access the WiFi hotspots.

The Elephant in the Room with Xfinity

I alluded to this earlier, but any Xfinity Mobile review on my behalf would not be complete without addressing the elephant in the room: my previous beefs with Xfinity customer service and pricing. I’ve written many articles over the years on topics such as how to get rid of your Xfinity modem rental fee, how to replace an Xfinity modem with your own, how to negotiate with Xfinity, how to cut your Xfinity bill, and so on. Xfinity is a publicly traded company – and as such, their goal has been to maximize profit through their fees, pricing, and contracts.

I do see the broader company making serious efforts to improve its customer service and experience. For example:

  • With Cable/Internet pricing, they have started offering existing customers extended contracts at prices previously only accessible to new customers (having to quibble over pricing and continual increases has long been a complaint of mine and others).
  • Their customer service reps do seem much more accommodating in recent years, which is a reflection of company policy.
  • Their revamped Xfinity stores are much closer to an Apple store than the DMV these days (I recently visited one and was shocked).

Xfinity Mobile reviewed as #1 in customer satisfaction compared to all measured full service providers in the 2020 American Customer Satisfaction Index® (ACSI) survey of customers rating their own wireless service provider’s performance.

I looked long and hard for gotchas with Xfinity Mobile. I wouldn’t say these are “gotchas”, but on the “unlimited plan”, the following applies, which is fairly common practice for unlimited plans these days:

  • Video streams up to 480p, standard-definition quality. HD streaming is available on Xfinity WiFi.
  • On any connected device, mobile hotspot speeds will not exceed 600 kbps.
  • When they added 5G service, they increased their lowest price from $12 to $15, but this was likely the result of a new contract with Verizon.

Aside from that, the pricing is fair, honest, and cheap. There is flexibility to switch plans. You can get 0% APR financing on phones if you can’t afford to buy outright (at the same total price). And you can BYOD without added fees.

I’ll be the first to let you know if any of this changes, but they’ve had a sound track record for over 3 years now.

Xfinity Mobile Promos and Discounts

Xfinity Mobile frequently runs promos and discounts. You can find a list of Xfinity Mobile promotions and discounts here.

They have been offering rotation promotions in the form of Prepaid Visa cards on a number of their devices. For example,

  • $200 card on any Samsung Android
  • $250 card on any iPhone
  • $25 if you bring your own device
  • A free Moto E or iPhone SE (see my iPhone SE review for more info).

Final Thoughts on My Review of Xfinity Mobile

If you’re already an Xfinity Internet customer, Xfinity Mobile is a great deal. I really appreciate:

  • the free unlimited nationwide talk & text on Verizon’s network
  • 5G access and strong internet performance
  • no line fees (unless you are no longer an Xfinity internet customer)
  • the ability to share data, with up to 10 lines on “by the gig” plans
  • the option of multiple data plans, and flexibility to switch
  • the ability to bring your own device (BYOD)
  • the extensive WiFi hotspot network to help keep data costs low
  • clear, fair, and transparent pricing
  • no contracts

If interested, you can get a discount on an Xfinity Mobile phone or bring over your own device here.

Review Summary:

Xfinity Mobile is a very strong prepaid mobile offering for Xfinity internet customers. They use Verizon’s strong network, but charge less than Verizon, and have flexible pricing options and month-to-month switching capabilities. There are no contracts, and no line fees (unless you drop internet service). While the phone offering was a little weak in the beginning, it has improved tremendously, and now includes Android, iPhone, and BYOD options.

I’m also impressed with the new phone and Visa debit card offers that Xfinity offers for new lines. They often included $250 off or cash back. And if you spread it across multiple months, there is a 0% APR.

Whether you want an unlimited plan, or you want a bare bones unlimited talk/text/minimal data plan ($15/talk/text/1 GB), Xfinity Mobile’s pricing is about as good as it gets.
