I looked at my bill online, and if you go through a few layers, you can view details, such as all calls and texts show the number and time sent or received.

As far as email and Messenger, those are data, which only shows up under the date and kilobytes used. I could not find any details on these.

I really don't think an employer would have the time to snoop through all this. But like the above poster said, the fewer the red flags, the better, I suppose.

Good luck!
