In the past, when Android was first commercially available to users, we all experienced high-speed 3G "technically". 3G generally provided us with signals from mobile networks around the world, but enjoying streaming or browsing the web without a website was not enough. Then came 4G and revolutionized the speed of cellular Internet.
