Can’t upgrade to unlimited data plan

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

Hello, @dior_11 how are you? Some things that come to mind are making sure you're logged in as the primary user, trying different browsers, devices and clearing cache, cookies, and history. This can help!

Do you have an owned modem or a leased Xfinity modem? If these steps don't help feel free to send us a direct message, so we can add unlimited data for you. The good news is you can add it mid-month to avoid any extra costs. 

You can use the Direct Messaging icon at the top of the page to send your name and service address to "Xfinity Support." It's next to the bell icon on the right side of the page. 

@dior_11 Thanks for allowing us to help. I'm glad we were able to add the unlimited data plan for a good price. If you need anything else, don't hesitate to make a new public post. Have a great day!
