I used jio last two months. It is good but not best. Jio says it gives the free 4G speed internet but it not really gives. It gives 2g and 3g speed of internet. The network is not available every where if available their is very poor signal. Therefore it not have a large network area. Jio’s internet is unlimited but is not really unlimited . It has daily limitation of speed after 4gb uses it speed is down it become 4G to 2G. Jio not provide full day 4G speed of internet . The calling experience is really very very bad . Everytimes say all lines are busy. There are so irritating. Jio not realible for calling purpose. Its gives free services is good but not best. There are Brand vaule is depends on its services.
