Hi, i got an unlocked galay note. I live in san francisco ca and have Att and was wondering how to get 4g lte on my phone or is it possible thanks for the help!! I think i just have 3g or 4g iono. It says 3g but when internet starts it changes and shows an H+ with little arrow going up and down. Is thay 4g or 3g thanks for that help too. Also when i got the phone i had to manually enter the proxy server and etc stuff to get the internet to work on my phone so if i need to change that what are the steps thanks.
