To add unlimited data to Xfinity, you have two main options if you are on an older 1.2 TB capped plan: switch to a current Xfinity Internet plan that includes unlimited data by default, or add the Unlimited Data option to your existing plan online, in the app, or by contacting Xfinity. All current Xfinity Internet plans now include unlimited data, so moving to one of those is the simplest path to avoid overage charges.
Check if you already have unlimited data
Before making any changes, verify whether your plan is a current unlimited-data plan or an older 1.2 TB capped plan. Log into your Xfinity account online or in the Xfinity My Account app and look at your Internet plan details. If you see "Unlimited Data" or a plan name that indicates unlimited data, you are already covered. If you see a 1.2 TB data usage plan, you are on an older capped plan and can proceed with one of the methods below.
Switch to a current Xfinity Internet plan
The simplest way to add unlimited data is to move from an older 1.2 TB plan to any current Xfinity Internet plan. All current plans include unlimited data by default, so switching eliminates data caps and overage charges entirely. To do this:
- Log into your Xfinity account online or open the Xfinity My Account app.
- Navigate to the "Manage Internet" section and look for available plan upgrades.
- Select a current plan that includes unlimited data and confirm the change.
After the switch, your data usage will no longer be capped, and you won’t pay overage fees.
Add the Unlimited Data option to your existing plan
If you prefer to keep your older 1.2 TB plan, you can add the Unlimited Data option. This removes the data limit and overage charges while keeping your current plan structure. Xfinity says you can add Unlimited Data online, in the app, or by contacting them. Xfinity says customers with Unlimited Data won’t pay overage charges and there is no data limit or overage charges on that option. After adding it, there is no data limit and you won’t pay overage charges. You can also remove the Unlimited Data option anytime by contacting Xfinity.
Use xFi Complete for unlimited data
xFi Complete includes unlimited internet data if you are enrolled in the 1.2 TB internet data usage plan. This option bundles unlimited data with an xFi Gateway modem and advanced security features. Note that xFi Complete is not available in Northeast markets. Xfinity’s 1.2 TB plan FAQ says the 1.2 TB usage plan does not apply to xFi Complete or Unlimited Data Option customers. If you are on a 1.2 TB plan and eligible, xFi Complete exempts you from the usage plan entirely. To add xFi Complete, log into your account and look for the option in the "Manage Internet" or "Upgrade Options" section. If you don’t see it, contact Xfinity to check availability in your area.
What about Xfinity Mobile?
Xfinity Mobile’s current plans are separate from home internet data. Both Mobile Select and Mobile Plus include unlimited cellular data, talk, and text in the US, but this does not add unlimited data to your home internet account. Xfinity Mobile’s current plan page says both Mobile Select and Mobile Plus include unlimited international data, talk, and text for 215+ destinations at no extra cost. If you are looking to understand how Xfinity Mobile work, it is a cellular service that runs on the Verizon network and offers its own unlimited data for mobile devices. However, bundling Xfinity Mobile with home internet does not change your home internet data cap. For home internet unlimited data, use one of the methods above. You can manage your Xfinity Mobile services and settings through the Xfinity Mobile section of your account, but those settings only affect your cellular plan, not your home internet data limit.
