I live just outside of 4G coverage and when I am on 3G, I get a download speed of 864kbps and upload speed of 748 kbps. However, when I switch on 4G, even though I don't get a 4G signal, phone still says 3G, I get a download speed of 1349kbps and upload speed of 656 kbps. I have tested this several times and every time it is faster with the 4G switch turned on. I do have 4G coverage at work so I know for sure that I am only on 3G at home. I would like to see if anyone else can test this out.
