If you want to keep Verizon’s network but lower your monthly cell phone bill, Xfinity Mobile offers one of the best wireless deals right now.

Smartphone data plans including 5G access now start at just $15 a month with Comcast’s Xfinity Mobile.

What Is Xfinity Mobile? Here’s What You Need to Know!

This service is only available to Xfinity internet customers. In this article, we’ll review everything you need to know if you’re thinking about switching to Xfinity Mobile.

Network Coverage

Xfinity Mobile customers get access to Verizon’s LTE network and 5G service in select cities nationwide.

A unique feature of Xfinity Mobile is that it provides access to 18 million Wi-Fi hotspots across the country. When you connect to one of them, you don’t use cellular data. That’s one way this service can save you money.

During my two years as a customer, those Wi-Fi hotspots helped me keep my average data usage below 1GB per month. Overall, I was pleased with the call, text and data performance.

Before you make the switch, verify that coverage is strong where you live. Here’s a link to Xfinity’s coverage checker.

Plans and Pricing

You must have internet service through Xfinity to sign up for the mobile deal. Subscribers get unlimited nationwide talk and text, and there are no activation or line access fees on up to five lines.

Xfinity Mobile introduced 5G data plans in May 2020. Here are the options:

  • Unlimited: $45/month per line on up to five lines; speeds reduced after 20GB
  • By the Gig: 1GB for $15/month, 3GB for $30/month or 10GB for $60/month; $15 per additional GB

With the By the Gig plan, data can be shared across all lines if you have family or friends on the account.


Flexible plan options differentiate Xfinity Mobile from its competitors. Customers can switch from By the Gig to Unlimited data during their billing cycle at no additional charge.

Also, accounts with multiple lines of service can mix-and-match By the Gig and Unlimited data options.

Unlimited calls to Mexico and Canada are available for $10 per month per line, and international long distance and roaming service is available in more than 200 countries. See the rates here.

Mobile Hotspot 

More and more low-cost cell phone service providers allow you to use your phone as a mobile hotspot including Xfinity Mobile. But your speeds will vary depending on the plan you choose:

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

By the Gig customers get faster speeds, but using a phone as a mobile hotspot on this plan counts toward your monthly data allotment. That could result in a higher bill.

On the other hand, those on the Unlimited plan will have to settle for slower speeds for hotspot-powered devices.

How slow is 600 Kbps exactly? Xfinity Mobile says Unlimited plan subscribers who use mobile hotspot should be able to check email and browse the web, but streaming video or music may result in buffering.

Video Streaming

Video streaming quality will also depend on which Xfinity Mobile data plan you choose.

If you sign up for the Unlimited plan, the resolution is set to 480p when you’re using cellular data. To watch a video in HD resolution (720p for phones, 1080p for tablets), you can buy an HD Pass for $20 a month per line.

In addition to improved video resolution, HD Pass includes better cell phone service during times of congestion.


For customers on the By the Gig plan, streaming in HD resolution is standard. But if you don’t need HD streaming, you can turn on Data Saver to limit data usage and keep your bill under control.

Here’s a tip: With either plan, connect to Wi-Fi to stream in high-definition without using cellular data.

Phone Selection

Xfinity Mobile now lets you bring your own Apple iPhone, Samsung Galaxy or Google Pixel device to the service. Follow this link to check phone compatibility.

If you prefer, you can purchase a phone from Xfinity Mobile. Options include:

  • Apple iPhone SE
  • Apple iPhone 11
  • Samsung Galaxy S20+5G
  • Samsung Galaxy A50
  • Google Pixel 4
  • Moto G7 Power

Xfinity Mobile sometimes offers phone deals, like up to $300 off when you activate a new line and transfer your number. Check Xfinity Mobile’s website for the latest deals.

In addition to phones, tablets and smartwatches are available for sale.

Customer Service

You can get started with Xfinity Mobile 100% online, but visiting your local Xfinity Store is also an option. Customer support is available over chat, text or by calling (888) 936-4968.

The Xfinity Mobile app is easy to use. It lets customers manage payment information, view data usage and switch plans.

Final Thought

By the Gig and Unlimited plans from Xfinity Mobile are priced competitively, but they don’t take into consideration the cost of internet service. After all, you must have an Xfinity internet account to sign up.

If you have Xfinity Mobile and later cancel internet service, you’ll have to pay a line access fee.


For that reason, I recommend this service for people who are happy with their Xfinity internet service and don’t plan to move out of an area where it’s offered in the near future.
