Is it possible to get a notification when I have used a certain amount of cellular data on my xfinity mobile account, eg 900 MB? I spent a long time on the online chat with an agent who thought it was possible but I do not have any of the "Notification" options she mentioned on either the xfinity mobile app, nor the xfinity mobile website. She thought maybe it was no longer possible. I have an iphone.
That should be in your phone: Settings search for Billing cycle and data warning scroll down to it, click on it and set the options you want.
