Now a day most trending sim in the market is of jio because of its unbelievable offer . Jio is giving free calling facility , free messages and free 4G net which is the main point for which people are buying this sim. I also have one sim in starting the speed of net was very good but as the time passes speed is constantly decreasing and call connectivity is also not good many friend of my are complaining that they can not call on my gio sim which is the main problem bt the connectivity improves at night.
