For activating a binge pack, you can pay it through any of the payment methods and using Tataplay balance is also one of the options. Once you have paid for it and activated any of the binge packs, it will be activated for an entire month and can be viewed irrespective of the balance in the Tataplay account. For renewing it in the next month, you should have sufficient balance and in that case, if you have less balance, it will not activate the binge pack due to insufficient balance.
