I must disagree with you. I tried doing the same browsing that I usually do with yahoo.com as my home page. On 4G LTE, I blew through 250 mg of data in what Verizon listed as 1 hour of connection (20 minutes for me). I still cannot figure this out.
However our daily usage for checking emails and browsing Yahoo.com is about 25mb.
I am still looking for a valid explanation of why so much more data went through, even if I had been on for 1 hour. During this time there were no updates or movies being downloaded.
