Flex Home Screen.jpg


Xfinity Flex brings you what you love, all in one place - your TV! And now, you’re eligible for Flex if you have Xfinity Internet, even if you don’t have Xfinity TV service.

With Xfinity Flex, you’ll be able to stream more than 10,000 free movies and shows, access premium subscriptions like Netflix, Amazon Prime Video, HBO and Showtime, and rent or purchase top movies and shows - all without switching apps or inputs, and with one-stop search and control thanks to our award-winning Voice Remote.

Flex customers can also access their music choices, like Pandora, iHeartRadio and Amazon Music. Certain Xfinity features are also available if you’re using Flex with an xFi Gateway, like pausing WiFi and setting parental controls through xFi.

To use Xfinity Flex, you'll need an Xfinity Flex streaming TV Box. The first Xfinity Flex streaming TV Box (a 4K-enabled box) is included with your Internet service. Each additional box is just $5/month. If you'd like to cancel your service for any reason, you’ll need to return your Box.

To get Xfinity Flex, go to and select Get Flex. You can also get Flex by calling 1-800-xfinity or visiting a retail store.




Eligibility Requirements

To qualify for Xfinity Flex, you'll need:
  • Xfinity Internet
  • TV with an available HDMI port

Please note:
  • You can have a maximum of three streaming TV Boxes on one account.
  • You must return your Xfinity Flex streaming TV Boxes upon the end of your Flex service.
  • If you're an Xfinity TV customer, you aren’t eligible for Flex.
  • Internet Essentials, Prepaid Internet and Bulk customers aren’t eligible at this time.



You can get Xfinity Flex shipped directly to your home or by picking up your equipment at a local Xfinity Store. If you pick up at a store, you should receive an Xi6 TV Box and an XR15 Voice Remote as part of your Flex order.

Just follow the instructions in the Self-Install Kit and you'll be up and running in no time. You'll need the phone number associated with your account when you activate the device, so have that handy.

If you’re renting a Gateway, it’ll automatically connect during the activation process for the TV Box. If you’re using an eligible modem that you purchased, you’ll be prompted to set up WiFi manually during activation.

As you activate your Xfinity Flex streaming TV Box, watch for tips and tricks to help you get the most of your experience, like how to easily find content or how to set up xFi if you’ve got an xFi Gateway.

Activation Troubleshooting

  • If you're having trouble activating your Flex streaming TV box, the most common solution is to restart it by reconnecting your USB-C power cord and HDMI cable to both the box and TV.
  • Make sure you’re connected to the Internet. Restarting your modem can fix many common Internet-related issues. You can also try to connect with a wired Ethernet cable to check if the issue is with your WiFi connection.
  • If you're having network connection issues or need to reestablish your network connection, you can press the WPS button (two arrows icon) on the bottom of the TV Box.
  • Until you're able to complete your Voice Remote pairing, make sure you point your remote directly towards the front of the TV Box.
  • If you come across an error screen and you can't fix the issue on your own, please mention the error code on the bottom-right corner of your TV screen when talking with us.
