I wish I could buy you a beer!!! So here is te rundown:3G radio? Do you mean someone told you it has only 3G cellular service connectivity? If so, that is wrong. It has 4G and will fall back to 2G if needed and possible since 3G service has been shutdown by carriers several months ago (starting a little over 1 year ago). You should see 4G show up in the upper right corner of the upper touch panel. If not, what does it show?
Can you supply more information about the problem?
