How do network providers keep track of data used?
I’m sitting here in a small closed room, deep in a building with poor reception. I click a link to open up a picture from the internet, and then it takes several minutes for the picture to load. If I had been outside, with better reception, the picture loads in under a second. So I am assuming the cell tower is continuously sending the information to my phone. Does the network read the amount of data sent by the tower or does it only count what my phone decrypts? Follow up question: if it only counts what my phone picks up, then wouldn’t that be exploitable?
