the difference of 2G 3G 4G era

- Apr 19, 2018-

2G era: call, send text message, send MMS, on wap page

3G era: In addition to the basic functions of 2G, you can also use video calls, downloads to watch video music and other multimedia, app-based speed Internet surfing (here I only outline, please add your own vain)

4G era: In addition to 3G features, there are services and applications such as HD voice, virtual reality, and real-world enhancements. (Because we only entered the foot of the 3G era, we haven't fully explored the applications in the 3G era, so we still don't recommend introducing 4G to ordinary users. Applications such as virtual reality are foreseeable, but they are still early in the business. So there is no way to explain it in detail.)
