Thanks bro! What I was doing wrong: trying to activate plan more than than the balance.Go to MyJio app and confirm it's login from your number only
Choose recharge option
Select payment option as balance
Remember you should have complete balance of plan like for 399 you should have 400 and also you can't use coupon but you'll get coupons of 50 rupees discount too.
