How do I change my mobile plan?

If you want to change your mobile plan, it's no problem. You have the flexibility to switch between Xfinity Mobile data options online or in the Xfinity app, and Xfinity has great choices. To learn more about Xfinity Mobile service, plans, and benefits, visit xfinity.com/learn/mobile-service.

If you choose to downgrade your plan, you’ll stay on your current plan until the end of your billing cycle. Your new plan will start at the beginning of the next billing cycle.

Change your mobile plan

Here's how to switch between data options using your Xfinity Mobile account online:

1. Login using the Primary or Manager's Xfinity ID.
2. Go to Activity > My Data.
3. Select a line.
4. Scroll to Data Options and select Change plan.
   
5. Review the Order summary, including the Estimated charges due on the next bill, and the Estimated monthly bill moving forward.
6. Select Confirm changes.
   
   
   • If you downgrade from Mobile Plus, you will lose the included Xfinity Mobile Care Plus (XMC Plus) protection for that phone line. If you don’t have any other phone lines on Mobile Plus, you will also lose device protection for any connected tablets and watches on your account.
   • Select any devices you’d like to keep covered with Xfinity Mobile Care (XMC) and confirm you agree to the changes.
   • Select Continue
7. Select Got it
   • Reboot your device after you change your plan.
   • *Service availability varies by location.

Here's how to switch between data options using the Xfinity app.

1. Sign in to the Xfinity app using the Primary or Manager's Xfinity ID.
2. Select the Services tab.
3. Select the Mobile lines and data usage located within the Mobile services card.
4. Select a line.

5. Under Line details, select your current mobile plan, and follow the prompts to upgrade your service.

   • You may be required to sign in again.
   • Reboot your device after you change your plan.

You'll be charged one price for all the data used by that line at the end of the month, based on which data option you choose.

By the Gig data option

The By the Gig data plan is only available to customers who joined Xfinity Mobile before April 22, 2026. If you already have By the Gig, don’t worry — nothing is changing for you. You can still manage your By the Gig lines anytime in the Xfinity app or at xfinity.com/mobile.

If you stay on your current pricing plan and remove all your By the Gig lines or switch them to an Unlimited plan, you’ll need to contact Xfinity if you want to go back to By the Gig.

If you move to the latest pricing plan, your By the Gig lines must be changed to either Mobile Select or Mobile Plus* and you won’t be able to move back to By the Gig pricing because the plan isn’t available on the latest Xfinity Mobile pricing plan.

*Service availability varies by location.
