My JIO app has a glitch which gives "Get a Jio sim" offer to most handsets if you go offline. Expect it to be fixed in upcomming update.Activated the unlimited offer in my g4 plus.I downloaded those 4 apps and went offline in myjio.Then i got this thing"Get jio sim" and I click on it.It will say no internet connection.Then switch on Wifi then click on "get jio sim" again .It'll show jio preview offer activated.
