  • Xfinity offers data plans that are flexible and inexpensive
  • Uses the powerful Verizon network to deliver one of America’s largest networks, Wi-Fi hotspots and 5G service
  • Frequent discounts on iPhones and mobile accessories
  • Only available to Xfinity internet customers
  • Slowdowns, throttling and data caps are to be expected

Xfinity Mobile has created wireless 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 that need more data should consider the unlimited 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.

Some potential downsides are the lack of any additional perks to the Xfinity plans, and the requirement to be an Xfinity residential internet customer to get Xfinity Mobile service.

Xfinity Mobile plans

Xfinity offers flexible wireless phone plans and fair pricing without hidden fees or contracts.

Mobile customers at Xfinity have a choice of two different rate plans depending on their needs and budget. These two plans are By the Gig and Unlimited. Both plans are similar in offering 4G LTE and 5G data access where available, as well as 4G LTE hotspots and high-definition streaming (with HD Pass, 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 could offer good value. This plan also includes an LTE Data Saver function to limit data usage. Pricing for By the Gig works out as follows:

  • By the Gig 1GB: $15/mo.
  • By the Gig 3GB: $30/mo.
  • By the Gig 10GB: $60/mo.

There is a charge of $15 per GB when you exceed the plan amount. No data rollover is allowed. By the Gig plans allow for a maximum of five lines, including tablets and smartwatches. Data sharing between lines is allowed with this plan.

If you aren’t using more than 3GB of data per month then By the Gig is going to be the most cost-effective choice. If you use more than that, Unlimited is the way to go.

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 a less expensive option. Here’s how Xfinity’s unlimited data plans compare:

Tablets and smartwatches can be added 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 promotions and deals

Xfinity keeps its costs low by avoiding perks and other possible gimmicks.

As mentioned above there are no additional perks 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 customers a great way to save is in the deals they offer on new phones. Current deals include:

Save $200 on any iPhone

With this deal, any new customer or new line activation qualifies for $200 off the purchase of a new iPhone. New customers must transfer their existing phone number within 30 days and the $200 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 $200 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.

Take $150 off an iPhone 11 Pro

This deal stacks with the prior $200 offer, so customers can receive a total of $350 off a new 512GB iPhone 11 Pro in Space Gray while supplies last.

Save $300 off the iPhone XS or iPhone XS Max

Customers receive a $300 credit on the purchase of an iPhone XS or XS Max. Cannot be combined with other offers.

Save $200 on an LG G8 ThinQ

While supplies last, customers can receive an LG G8 ThinQ for just $579.99. This is a $200 savings off the regular retail price.

Save 25% off select accessories

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

How do Xfinity’s cellphone prices compare?

Xfinity doesn’t have the widest variety of mobile phones available, nor do they have the cheapest in most cases, but they do have solid offerings overall. The brands on offer as of July 2020 are:

  • Apple
  • Samsung
  • LG
  • Motorola
  • Google

If you look at the average price across all phones available then Xfinity seems to stack up very well, but on a case-by-case basis you’ll find that for almost every model there is another provider with a cheaper, and sometimes substantially cheaper, price.

Xfinity’s average prices for popular phones come out to around $794, compared to $653 for AT&T, $721 for Verizon and $843 for Sprint.

For example, when looking at iPhone models there is not one single case where Xfinity has the lowest price, although in most cases their price is the same as other carriers. Primarily, this is because AT&T features very low pricing on many iPhone models. At Xfinity, the best deals are the items on sale, such as the current sale on iPhone 11 Pro handsets. Xfinity also has a good deal on the iPhone XS Max, with its $699.99 price tag coming in $200-$300 lower than most competitors, although AT&T offers the model for $600.

The same is true for Google Pixel phones, where Xfinity is equal to slightly cheaper than competitors, with the exception of AT&T, where the Pixel is roughly 60% cheaper than Xfinity’s prices.

Xfinity’s LG offerings seem to be where it shines, with the carrier offering the best deal on the LG G8 ThinQ. Again, AT&T might be a better option for hardware, with that carrier selling the LG V60 ThinQ 5G for just $300.

There are very few Motorola handsets on sale anywhere, but Xfinity and Verizon match prices on the two models they do offer.

In the case of Samsung phones there’s a huge variety available. Xfinity has the best pricing on the various Galaxy Note10 models. It also has the best Galaxy S20 pricing by a couple hundred dollars. However, those looking at the entry-level Galaxy A51 would pay $399.99 at Xfinity while they could get the phone for just $30 from Verizon and free from AT&T.

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, 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 506.1 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 0.5% of the time, versus 19.8% for T-Mobile, 10.3% for Sprint and 9.7% for AT&T. So the Xfinity users had amazingly fast download speeds when connected, but other carriers’ customers saw improved 5G download speeds 20-40 times as often.

As of May 2020, Xfinity offers 5G service in 34 major cities across the U.S. plus the District of Columbia with coverage expected to expand nationwide in the future. The 5G service is included in all plans without additional costs, and speeds are up to 20 times faster than 4G service. Cities currently included in 5G coverage are:

  • Atlanta
  • Boise
  • Boston
  • Charlotte
  • Chicago
  • Cincinnati
  • Cleveland
  • Columbus
  • Dallas
  • Denver
  • Des Moines
  • Detroit
  • Grand Rapids
  • Greensboro
  • Hampton Roads
  • Hoboken
  • Houston
  • Indianapolis
  • Kansas City
  • Little Rock
  • Los Angeles
  • Memphis
  • Minneapolis
  • New York City
  • Omaha
  • Panama City
  • Phoenix
  • Providence
  • Salt Lake City
  • San Diego
  • Sioux Falls
  • Spokane
  • St. Paul
  • Washington D.C. 

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:

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.

Can I bring my own phone to Xfinity?

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

Which Xfinity plan is best?

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.

Can I get Xfinity Mobile if I’m not an Xfinity internet customer?

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.

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.
