As the world is pacing by, we can see a significant advancement in technology and electronic gadgets. Consider the time when we used the 2G internet network.
But, it was too slow and time-taking to open any website or download files. The 3G wireless network came on 1st September 2010. It was definitely faster than a 2G network.
