Network coverage is good but not very good because day by day user are increased so that’s why network coverage are little bit down that time but its totally free. The service of this company is for me any company will give free service of data and voice is totally free there is no matter about service and all, I am using full 4g data service of jio with any cost I am very happy no tension about billing no tension about charges its free for the time I suggest to the people who never use jio please only one time take this service and enjoy
