Reliance gio is giving three monthes of free service including free call for life time over lte and three monthes of 4g data and sms.But from my personal experiance I can tell you gio is not provoding that much speed.i never get 4g speed during download.but on playstore and youtube it is givining almost 4g speed.basis of calling gio is not greate in my city I do not get full tower but when out of home sometimes I get full tower.during most of the call it says all route is busy. otherwise this is a good telicom brand.
