  • Only available to Xfinity internet customers
  • Offers flexible and inexpensive data plans
  • Uses the Verizon wireless network, with access to Wi-Fi hotspots and 5G service
  • Frequent discounts on iPhones and mobile accessories
  • Slowdowns, throttling and data caps are to be expected

Xfinity Mobile offers cellphone plans that are both inexpensive and flexible, thanks to an arrangement to use the Verizon network to deliver service. And they keep it simple by offering just two plans: one for unlimited data, and one for those who want to pay for a set amount of data. Those who use 3GB of data a month or less will be best served using the By the Gig plan, and those who need more should consider the unlimited data plan.

Xfinity even scores better than Verizon in some consumer surveys, likely due to Xfinity’s network of millions of hotspots across the U.S. that almost ensure users will find a location to connect to.

Xfinity Mobile: How it works

Xfinity’s cellphone service is a little different than most carriers, because you must be an Xfinity internet customer to sign up. If you do already get your internet from Xfinity, it’s pretty simple to add a cellphone plan to the mix. Xfinity doesn’t require contracts, so you’ll only pay month-to-month for your service. 

Once you decide between a By the Gig plan or unlimited data, you can get a new phone through Xfinity or simply bring one you already own. Your phone number will come with you when you make the switch. 

Xfinity Mobile plans

Flexible phone plans and fair pricing without hidden fees or contracts.

Mobile customers at Xfinity have a choice of two different types of plans depending on their needs and budget: By the Gig and Unlimited. Both plans include 4G LTE and 5G data access where available, as well as 4G LTE hotspots and high-definition streaming with HD Pass for an additional $20/mo.

By the Gig lets customers pay based on their monthly data usage and may be best for those who aren’t heavy data users. If you primarily use your phone for talk and text, without a lot of video streaming, By the Gig offers good value. These plans all include unlimited talk and text, plus an LTE Data Saver function to limit data usage. Pricing for By the Gig works out as follows:

  • $15/mo. for 1GB
  • $30/mo. for 3GB
  • $60/mo. for 10GB

There is a charge of $15 per GB when you exceed the plan amount, and no data rollover is allowed. By the Gig plans allow for a maximum of ten lines, including tablets and smartwatches. There are no fees for extra lines, but the data you use is shared across all lines.

Unlimited offers no data cap for a set monthly fee of $45 per line. When compared with other providers this is very inexpensive — until you get to three lines. At this point, most phone companies start giving you discounts, but Xfinity’s pricing is $45 per line no matter how many you add. Those who need four or five lines may want to consider going with a cheaper family plan. Here’s how Xfinity compares to the cheapest unlimited plans from other carriers:

With AT&T, T-Mobile and Verizon, you’ll typically get better perks like streaming subscriptions and cloud storage. And because those companies operate their own networks, you’ll usually get faster and more reliable coverage, too. 

Tablets and smartwatches can be added to Xfinity Mobile accounts as either By the Gig or Unlimited plan lines for $10/mo. They do count as separate lines, but share data with the host phone.

Xfinity Mobile phone deals

Xfinity offers some discounts on phones, but they aren’t as generous as you’ll find with bigger wireless carriers.

As mentioned above there are not many extra perks like streaming subscriptions and cloud storage being offered with Xfinity Mobile plans. Their strength is offering low-cost wireless service. By avoiding additional perks they are able to keep per line costs low, while also avoiding activation fees, line fees and contracts. 

Where they do offer some opportunities to save is in their deals on new phones. These are some of the best ones going right now.

$250 off all iPhones

With this deal, any new customer or new line activation qualifies for $250 off the purchase of a new iPhone, with the exception of the iPhone SE. New customers must transfer their existing phone number within 30 days and the $250 is applied as a credit over the 24 months of the payment plan. Existing customers can also take advantage of the deal and will receive a $250 Visa Prepaid Card.

Get $50 when you bring your own phone

Those coming from another carrier will receive a $50 prepaid gift card when they bring their own phone and switch. Users get to keep their existing phone number and a SIM card will be delivered right to their homes with easy to follow instructions.

Save 25% off select accessories

Purchase new accessories for your phone and get 25% off. This deal doesn’t include Apple and Samsung branded products, but it’s a great way to get a new phone case with a discount.

Xfinity Mobile coverage and speed

Xfinity offers up excellent coverage across the U.S. and reliable, if sometimes slow, speeds thanks to its use of Verizon’s mobile network.

We’ve already mentioned that for users that only need one or two lines Xfinity is the cheapest option among the major mobile carriers. But what kind of performance do you get? The good news is Xfinity doesn’t have its own mobile network. Instead, it uses the Verizon network, which happens to rate top scores in many of the categories users care about, such as coverage, reception and video streaming.

As you can see from the table above, Verizon comes in at the top of these categories, and so Xfinity does by default as well. The one caveat to this — for Xfinity users on the unlimited data plan, after 20GB of monthly data use, speeds are reduced to a maximum of 1.5 Mbps download/750 kbps upload. And video streaming is at 480p by default, although higher resolutions are available for those willing to pay $20/mo. for the HD Pass service.

It’s interesting to note that in some surveys, Xfinity actually has somewhat better coverage ratings than Verizon. This could be because the Xfinity network is bolstered by millions of hotspots across the U.S.

How is Xfinity’s 5G network?

Based on research conducted by OpenSignal, Xfinity’s 5G network (Verizon) outperforms other networks in several metrics. The most notable of these is download speeds, where the network download speed was measured at 494.7 Mbps, which was nearly twice as fast as the nearest South Korean competitor and nearly five times as fast as the nearest U.S. competitor. 

However, Xfinity users found their ability to actually connect to a 5G network was just 0.4% of the time, versus 22.5% for T-Mobile and 10.3% for AT&T. So the Xfinity users had amazingly fast download speeds when connected, but other carriers’ customers were connected to 5G 20-40 times as often.

How does Xfinity compare to other wireless providers?

Xfinity combines low costs for users who need one to two lines or those who have limited data needs, with the top nationwide mobile coverage provided by the Verizon network.

Xfinity compares very favorably with other wireless carriers thanks to its use of the top-rated Verizon Wireless network and its low cost when compared with other providers. Of course, that’s somewhat offset by the data throttling and low-resolution video streaming offered by Xfinity. Those who choose to pay for faster data transfer and higher resolution video might find themselves paying more than with other comparable wireless networks.

When it comes to customer service the entire wireless space is often given a bad rap. Xfinity is lumped in with that group, but it has been making improvements to the customer service experience. Overall you could consider Xfinity a solid, inexpensive option for those who are already paying for Xfinity internet.

Xfinity Mobile customer service

When Xfinity launched their mobile service in 2017 the ratings for customer service weren’t good. That continued into 2018, when the American Customer Satisfaction Index (ACSI) report ranked Xfinity seventh among internet service providers and 10th among fixed line providers. That’s changed dramatically and as of 2020 the ACSI report ranks Xfinity number one in customer satisfaction among full-service wireless providers. Here’s how you can get a hold of them:

Should you switch to Xfinity Mobile?

If you’re already an Xfinity residential internet user and don’t need more than three lines, choosing to go with Xfinity Mobile is a good move. The combination of the Verizon network and millions of Xfinity hotspots, plus the cheap pricing of one- to three-line plans means you’ll be getting excellent service all across the U.S. without paying the high costs of some of the major mobile providers.

That said, you will have to deal with the throttling imposed by Xfinity after you exceed 20GB of monthly data, and you’ll also have to deal with low-resolution video streaming all the time unless you want to pay an extra $20/mo.

If you don’t use a lot of data to begin with you will be even better served by the By the Gig plan, where you can get up to 3GB of monthly data for just $30 without throttling and with higher quality video streaming.

Xfinity Mobile FAQs

Are there any additional costs or fees with Xfinity?

Xfinity is somewhat unique in that they don’t require a contract, so there are no early cancellation fees. They also have no line charges, no activation fee, no overage charges and basically no hidden fees. You are required to have Xfinity internet to use the mobile service, and that could be considered an additional cost.

Not only can you bring your own phone, Xfinity will give you a credit if you bring your own phone (as of December 2020). They will also allow you to bring your phone number along, saving you the hassle of getting a new number.

With only two options to choose from you may not need a long time to figure out the best answer for you. Basically, if you use more than 3GB per month of data, which costs $30 and has a $15 per GB charge if you go over, it’s best to get the Unlimited plan. If you use just 3GB or less per month, go with the By the Gig plan. You might have to sign up for By the Gig first to see how much data you actually use each month if you don’t already know.

You cannot get Xfinity Mobile if you aren’t an Xfinity residential internet customer. However, you can keep your Xfinity Mobile plan if you’ve signed up already and later drop your Xfinity internet. A $20/mo. additional charge applies in this case.
