Normally we see "get JIO sim" option when we have installed all 10-11 JIo apps. So even while trying to activate unlimited offer, these apps should not be uninstalled? Asking since the procedure mentioned in the link shared by you says un-install all jio apps.
Does it means that Username / password entry field and Get offer TAB appear on same screen? In my case if I enable data on the password screen it is unable to log in.
