I got a message for STB delivery, I haven't opted for any plan other than 199 plan so don't have one. I did see the message on Jio app as well. From the various CC I contacted you can use the link on sms to get STB delivered or contact CC to arrange appointment for STB installation but you need to select a plan like 699/849 etc to avail the STB. Regarding 199 plan what I've mentioned earlier is what I know. Wait till 2mrw for more info on tht. If your free offer is still working, enjoy till it lasts. (BTW the Jio sales guys in my area were not helpful either)
