After launching in mid-2017, Comcast's Xfinity Mobile service has slowly been improving by expanding availability and growing its device lineup. Now Xfinity Mobile is rolling out a new feature for its customers.

Xfinity Mobile customers can now bring their own device onto the service. Select unlocked iPhone models are available for Xfinity Mobile's Bring Your Own Device (BYOD) feature to start, including the iPhone X, iPhone 8, iPhone 7, iPhone 6s, iPhone 6, iPhone 5s, iPhone 5, iPhone 5c, and iPhone SE. You can go to this page to determine if your specific iPhone model is compatible.

If your device is compatible with Xfinity Mobile's BYOD program, you can bring it in to an Xfinity store and a representative will help you activate it on Xfinity Mobile. If your device isn't compatible, you may be able to trade it in to Xfinity and get a gift card to use for upgrading to a new device.

Additional devices are expected to be added to Xfinity Mobile's BYOD program later in 2018.

Letting customers bring their own device when switching to a new network can help convince them to switch. Not only does it make the switching process easier since they can keep their phone rather than upgrading to a new device and transferring their data over, but it's also cheaper since they don't have to shell out hundreds for a new device.
