Few time ago no one know about what is gio now if you ask anyone what is 4g they say gio. The reason behind this is free Internet and calling services of gio to all its customers. Now gio giving excited offers for their customers. If you want to experience true 4g experience with low price. You go for gio but one drawback of gio is poor network and uneven Internet speed other than this gio is best for common people. I am telling you all this after using reliance gio from one month. Thank you guys
