Is there a way to see details of data usage (when/how much was used), not just summary? It says I have used 2gb in less than 4 days, which would be highly unusual for me… I typically use about 8-10gb in a month.
the usage summary button only seems to show telephone and sms
@Tashik unfortunately not. PM won't be able to give you detailed reporting. As mentioned below, best bet is to check your phone to see how much cell data has been used and when. I think Android can provide more detail, iPhone has some data but not in great detail. Iphone can sort by which apps have used the most data, but not to the detail you're looking for.
it is very difficult to detect your data use from carrier service, it could involve in your personal information. but you can check your personal data use from your phone. If you are using iphone, you go to settings and then go to cellular, scroll down the list, and the data usage will show up there.
