Hello - I know this question has come up before, but I have not seen any threads recently and am wondering if anyone can help. I upgraded one of my lines from a 4s to a 5 (right before the 5c and 5s were released). This line previously used about .5 GB data per month. In the first 10 days since I had the 5, Verizon is reporting this line used 2.3 GBs and the phone itself says 150 MB. Can anyone explain what is going on and how to fix this? I understand that LTE uses more data than 3G, but not 5x the amount of data. I've called Verizon and Apple and nobody is helping. Thanks!
