I have had a uscell wireless broadband account with a 5 gig limit for the last 7 years. I've seen the overage cost go from 50 cents a meg to 10 dollars a gig. When you get charged 50 cents a meg for overages, you learn real quick how to track and estimate your usage. I've been within 100 meg many times and within 2 to 300 meg consistently. NOW...I bought a NOTE 3 connected to the share everything plan through Verizon that started on the 1st of January. I have already used 2.5 gig in 7 days. Hey, I understand data usage but when I download files that are between 250-300 meg total(I put them in their own folder to ease measuring) but my data usage show between 700 and 750 meg? I am using it as a password secured hotspot to connect to my laptop wirelessly. I am the only user. A sales person speculated that because I'm connecting at 4g rather than 3g that I am using more data. Not sure how downloading a 40 meg file using 3g magically becomes(guessing) 100 meg using 4g.? data is data so how does the file get denser based on 3/4g? I have tried to a hardline tether from the phone to the pc and that seems to use less data? Is there a doubling of data transmission that gets accumulated? 1 time from the network to the phone and then again from the phone to the laptop? As I said, I understand data, did 26 years in IT, converted bits, bytes, into k, meg and now gig and beyond but this doesn't seem right to me.
