Jio is suddenly emerging mobile network due to its very cheap offers and high speed . I also used it and it work perfectly for a while. With the increase of popularity and usage in public, signal strength started decrease and after that no speed is there . To open a simple website like Facebook or playing a video it take lots of time & get a heavy lag. Cost of plan started increasing. If we ask something about our plan or complaint about the network from executive they behave very rudely to us which is very disappointed. So may be this will help you to choose your network
Thank you
