Hello wchang207, thank you for reaching out to us here with this concern. Due to COVID-19 I myself have had to add unlimited data to my data package as well so I know how important it is to have this feature while working from home or if you just spend more time using your data services. I'd be happy to help you add the unlimited feature to your account, for further assistance please send me a private message with your full name and account number by clicking on my name (ComcastAmir) and then click "Send a message".
Thank you for this information Wang, let's get this feature added to give you the peace of mind in not going over your data cap. Before submitting your order, I want to spend a few minutes confirming with you that I've accurately captured the services you want. I'll ask you to review the order and, if it's correct, to please approve it. What phone number or email address would you like to use to complete this process?
