My wireless bill is now the cheapest it has been since I got my first cell phone more than 15 years ago.

For the past year, I’ve tested out Comcast’s Xfinity Mobile, a cell phone service from the cable and internet giant that’s designed to help you save money.

Here’s a snapshot of the billing details on the last day of my first cycle:

How did I manage to lower my monthly cell phone bill to just $12 before taxes and fees? It was surprisingly simple. And there’s even a way for light data users to pay $0!

I’ll share more about my experience later on, but first here’s how Xfinity Mobile works…

Everything you need to know about Comcast’s Xfinity Mobile service

Verizon’s 4G LTE network + Xfinity’s Wi-Fi hotspots

Xfinity Mobile runs on Verizon’s strong and reliable network, but it’s Xfinity’s more than 18 million Wi-Fi hotspots nationwide that can help subscribers cut costs by only paying for the data they use.

In addition to using Wi-Fi at home, nearly 70% of customers connect to those hotspots while on the go to limit data usage.

Xfinity Mobile: How much does it cost?

You must have internet service through Xfinity to sign up for the mobile deal. It includes unlimited nationwide talk and text, 100 MB of shared data and no line access fees on up to five lines.


After using up the 100MB of included data, there are two monthly data options to choose from:

  • Unlimited: $45 per line on up to five lines; speeds reduced after 20GB
  • By the Gig: $12 per GB of shared cellular data across all lines

Using only that 100MB of shared data, extremely light data users could potentially have a $0 monthly bill before taxes and fees, a Comcast spokesman confirmed to

One of Clark’s Facebook fans said that’s what he does:

Bobby: “I’ve been using it for a few months… and have kept it under 100MB most of those. Service has been great… I hope this stays a ‘secret.'”

Subscribers would still pay the monthly installment on their phone, if applicable.

Switch back and forth between plans

One thing that makes Xfinity Mobile unique is its flexibility. 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.

You may not be able to bring your own phone 

Xfinity Mobile now lets you bring your own unlocked iPhone to its network, but Android users will have to wait for that option. Here are some of the smartphones that the wireless provider sells:

  • Apple iPhone XR
  • Apple iPhone XS
  • Apple iPhone XS Max
  • Samsung Galaxy S10
  • Samsung Galaxy S10+
  • Samsung Galaxy S10e
  • LG Stylo 4
  • LG K30
  • Motorola moto e? play

Xfinity Mobile sometimes offers phone deals, like $200 off when you activate a new line and transfer your number. Check Xfinity Mobile’s website for the latest deals!

My experience with Xfinity Mobile

Moments after the Samsung Galaxy S8 I bought through Xfinity Mobile arrived at my door, I was up and running.

There have been no issues with call, text and data performance during my first year of service. I’ve also been impressed with the number of Xfinity Wi-Fi hotspots that I’m able to connect to when I’m away from home or work.


Take a look at how those hotspots helped me keep my data usage to 0.4GB for one entire billing cycle:

By limiting Facebook activity when I’m not connected to Wi-Fi, activating Chrome’s Data Saver and utilizing Wi-Fi only mode for Google Maps, I’ve used even less cellular data than I expected.

Xfinity Mobile makes it easy to monitor your data usage, refreshing it every 20 minutes in the app.

I also like how I’m not tied down to the “By the Gig” plan. If my data usage happens to spike for some reason, I can switch to “Unlimited” without being penalized.

However, with Wi-Fi available in so many places, I’ve been happy with the “By the Gig” plan so far.

UPDATE: After my first 12 months with Xfinity Mobile, I’ve paid a total of $180.11 for cell phone service, including taxes and fees. That works out to just $15 a month!
