run jio 4g in 3g smartphone -

I heard somewhere that we can run JIO 4G sim in 3G devices and wondered that how is it possible? because JIO is a pure 4G network. So, if we look technically, it is impossible I thought. But, I personally tested myself and found that I got a network of JIO in my MOTO G2 as well as I can use it’s Internet without any problem.

So, I today tell you some of the different methods to run JIO sim in your 3G handset.
