Starting March 22, 2024, all new Xfinity Mobile customers choosing the By the Gig data option will have one option for By the Gig. That's 1GB of data that can be shared with others on your account. You can upgrade your account to the latest plan by visting My Account online or the Xfinity app.
If you're on our second-, third-, or fourth-generation plans you can choose between three By the Gig data amounts. Our second-generation plan comes with a choice of three By the Gig data amounts. But just because you choose one when you sign up, it doesn't mean you have to stick with it. You have the flexibility of changing your data amount based on your needs.
If you're not using as much as you expected, you can change to a smaller amount. If you're using more than you expected, you can go up to a larger amount.
Are there any restrictions to changing my data amount?
You can change as often as you'd like, at any time in your billing cycle. You'll pay for the amount you're on at the end of the billing cycle.
The only exception is that you can't change to a smaller amount if you've already exceeded that threshold. For example, if you're on a 10 GB amount and you've used 7 GB, you're unable to change to the 3 GB amount.
