What you have mentioned is exactly what I have been doing since I've gotten the phone. My web browsing routine involved turning off data(via data toggle in the notification pan) and only having wifi enabled. with that being said; Does the phone continue to use the 4g lte even with data turned off and wifi enabled? Also,I am waiting for a reply to the my verizon app problem. On both website and mobile app, I am at 901mb of the 2gb limit. While a text was sent to me that I am at 75%. The data monitoring feature in the phone settings also states I am at 901mb. Just to put it out there, the same monitoring app( the one found in the phone settings) states I am at 9GB data consumption via wifi.
