“Impact of the mobile phone
While 2G and 3G basic and feature phones were tremendously important for people to open their worlds, be able to communicate whenever and wherever they wanted and made life so much easier, 4G enabled the smartphone to revolutionize our lives in ways that go well beyond how we communicate. Besides calling and texting, almost 4 billion people around the world are connected to the mobile internet and use their devices to send money, navigate, book cab rides, follow the news, learn a new language, watch movies, listen to music, play video games, memorialize vacations, and, not least of all, participate in social media.”
