Xfinity Mobile An Overview

Xfinity Mobile is an MVNO that launched in 2017 and it is owned and operated by Comcast.  It operates on Verizon’s network.  Phones can be configured to automatically connect to Comcast Wi-Fi hotspots to provide data to subscribers. Wi-Fi calling is supported for iPhones and select Android devices.

Xfinity Mobile is only available to those who are also subscribed to Comcast’s Xfinity Internet.  Despite that limitation, Comcast was able to grow its subscriber count rapidly.  Comcast acquired 380,000 Xfinity Mobile subscribers just months after launch.

Xfinity Internet subscribers used to be able to get unlimited talk and text on Xfinity Mobile with 100MB of shared data free of charge.  However, on August 1st, 2019, Xfinity Mobile reconfigured its wireless plans to Second Generation.  Second Generation plan subscribers no longer get unlimited talk and text free of charge or the first 100MB of shared data for free.  First Generation plan subscribers are grandfathered in and allowed to keep their plans if they so choose.

In May of 2020, Xfinity Mobile issued another plan update. The base By the Gig plan price was increased to $15/month. However, subscribers on the plan now get 5G data access if they have a compatible phone and live in a location serviced with 5G. Another important plan change to note with the update is that subscribers now have higher network priority access. Priority access is now more in line with those that subscribe to Verizon’s postpaid network.

The Xfinity Mobile’s unlimited data plan priced at $45/month only contains 20GB of high speed data before data throttling to a maximum of 1.5 Mbps download and 750 Kbps upload.  Subscribers on a shared By the Gig data plan can have up to 5 total lines on their account at no extra charge. So an account with 5 lines with 1GB of shared data will be billed just $15 per month total with overages charged at a rate of $15/GB.  In contrast, unlimited plan subscribers must pay $45/month for each line that they have that is unlimited.  Customers are allowed to mix and match plans.  As an example, a customer with 5 lines may have 4 By the Gig shared data lines with 1GB of shared data for $15 total, while the 5th line would be billed at a rate of $45/month, making the account holder’s total monthly bill cost $57/month.  Taxes and fees are extra.

Where To Buy Xfinity Mobile Service Plans And SIM Cards

Since Xfinity Mobile is only available to Comcast Internet subscribers, service and SIMs can only be purchased directly from Xfinity Mobile.

Supported Phones And BYOD Devices

A variety of phones are available for purchase.  Xfinity Mobile sells all the latest devices including Apple iPhones and Samsung Galaxies.  Phones from LG and Motorola are also carried.

Bring your own device is supported for iPhones and Samsung Galaxy devices including the S8, S8+,S9, S9+, Note 8 and Note 9.  Your iPhone must be out of contract and compatible with Verizon’s network to be able to use it.  Supported Samsung Galaxy devices from any carrier should work if they have been unlocked.

Xfinity Mobile Customer Support

Customer support is available through Facebook Messenger, online chat, text messaging and over the phone at 1-888-936-4968.

Before you buy Xfinity Mobile, know these restrictions (not in their FAQ or ToS):
1. (Confirmed) Your phones will always stay associated with the line Xfinity Mobile originally activates. You can swap SIMs to another phone, but the latest Xfinity backend system won’t show this to you in your account, or let you or Xfinity Mobile staff update devices shown in your account. Neither the store nor telephone CS can help you do this. If you request a CS ticket, it will fail. If the phones you used are BOTH BYOD, you can port out BOTH phone numbers and port them back in to update your account.
2. If you buy insurance for a new Xfinity Mobile phone, the insurance is associated with the original line and phone, even if you swap in a different Xfinity Mobile SIM card. To file a claim, you have to give Assurant the original phone number and IMEI combination, or they will reject your claim. Assurant will not suspend your phone line; you call Xfinity Mobile CS to do that. When you receive the replacement phone and SIM, Xfinity CS activates it with the original phone number associated with the lost or stolen phone.
3. If you port out out a phone number associated with a phone you bought from Xfinity Mobile, a Xfinity Mobile CS supervisor told me they will block the phone from working with Xfinity Mobile service. If Xfinity Mobile unlocks that phone (after it is paid off), they would still NOT activate that blocked & unlocked phone again. It will be blacklisted from further use with Xfinity Mobile even if you swap in an active Xfinity Mobile SIM. You would have to BYOD a different phone originally bought from another carrier or dealer to activate a new line, or buy another new Xfinity Mobile phone.

Do you know if xfinity mobile has access to Verizon’s extended network? I know some of the mvno’s have access and some don’t. I’ve been getting mixed answers from Xfinity when I talk to their customer representatives. Half of them have no idea what I’m talking about. I’m referring to the towers that aren’t owned by Verizon, but the ones they have agreements with for post-paid accounts. Extended network, roaming, etc. Is the xfinity coverage exactly the same as post-paid verizon wireless cover? Thanks!
