Same situation bro. Actually on JioTV Web Version, I was not able to sign it. It said Invalid Credentials. So I just logged in to my jio account to see if my credentials that I was entering were correct and holy cow! I see 10GB credited same day (yesterday) around 3PM. See your recharge history- It shows Recharge of Rs 301 done on 28-Feb.
I havent yet put SIM in my phone. Should I put it, are u able to use without Prime subscription?
I guess they are doing it to keep sim active
