I brought jio sim one month ago, because there is viral for jio. But when I insert sim in mobile and there is verification and then it say start tomorrow 11 a.m. I wait till tomorrow and not start till 6p.m I called customer care they say it will start tomorrow .and tomorrow it start around 9p.m. it waited me so long. So now I start free calling but it didn’t call anybody in 3to 4 time so basically network is not so strong and call dropping is major issue .so for emergency it didn’t call u need an secondary sim for calling. Now it turn for internet and4g and I was very excited but it give speed 4mbps I say ok but slowly slowly speed down to 1mbps and some time give me in 500kbps oh it not 4g it is slow I it is 2g.i humble request don’t use jio because bad network call dropping and slow internet connection.
