This is a true 4G network. The internet speed in my area is about 30 MBPS and voice quality is top notch.
Even in areas with low signal I manage to got about 5 MBPS. It has 3 LTE bands so by default it will connect to the band with highest signal so you will always be connected to the internet but with a fair speed ( 2-5 MBPS ) .
Superb network !
