MyVerizon used to have a way that my detailed bill would tell me how much data, what time, and potentially a location that the data I'm being billed for was used.
I'm aware of how to use the Usage>Data page to look at which phone on my account is using the most data. I'm aware that I can look at types of data that are generically categorized like "Games" vs "Social Media." There used to be a way that you could get a report that showed a timestamp, amount of data, and location (probably a cell tower).
I'd like to know where my data is being used so I can potentially fix wifi connectivity issues when we travel.
