Gio is the best net using simcard. And the best part of this card is that this is absolutely free of cost. and the speed. What can we say about it, just its is lightning fast.I can say that this is the best ever speed I am using or used in my life. And with that they are giving us free applications also. in that we can see movies with best quality. the best part I already said that its speed we can operate 3-4 mobiles at a time without buffering. so I must say that we should take this but as coin has two sides it is also having that sides that means it is also valid for the 31st december of 2017 and it only works on the 4G mobile. so only latest 4G mobiles are usefull for this. I dont know what ambani sir are going to do after 31st december but now this is the best ever sim card.
