I m using jio for a long time, previous days network worked fine but after 3 months speed reduced day by day.sometimes I feel very worst about the speed, u can, t download any movie better and u can, t play any video without buffering, I feel angry but now I will port .if u talk about call. U can, t talk sudden to anybody, because the network drop the call minimum 3 times then u may talk, sometimes u will be unable to hear the clear words of othersides and same there, mean otherside person also not be able to hear clear voice.bad feeling.
