I have the Performance Plan along with the Flex Box which I have been using a lot during the Coronavirus shutdown. I am up to 281 GB already in April. The graph seems to only go up to 300 GB. So I am guessing that is the monthly limit. Does any one know how I can find out what my data limit is? Is is not on my bill because with this plan I have auto pay and online billing. I live in PA so not in tetrabyte area.
The graph expands as your usage rises, it just happens to be at 300 at the moment. As you use more data it will expand farther.
There is no data limit in PA. Please see https://www.xfinity.com/support/articles/data-usage-plan, especially https://www.xfinity.com/support/articles/data-usage-find-area.
