Nice to have 4G available, you should notice better data rates, unless the signal is really weak. Sounds like your carrier is using different spectrum for 4G which is the normal. Last I looked Wilson didn't have a single solution to covered the 3G data/voice spectrum and the 4G Data solution. So you will need an additional solution to amplify the 4G signal. Kind of a pain but needed until the carriers move to VoIP over 4G and move away from the current circuit data solutions.
