If they happen to be using OOKLA Speedtest to check data speeds, it can consume a huge amount of data before you realize it. I burned up 626mg of data the first day I got the S4 after switching to Verizon from Sprint, LOL. Never realized Speedtest used that much because of the miserably slow speeds I was getting on my Sprint phones. Was wonderful to finally see great download speeds everywhere I went, until I realized those 50Mbps speed checks were actually using 50mb of data every time I did it
