14. Is it necessary for customer to have another additional Data quota or additional Data balance on my mobile to use unlimited YouTube, Facebook, WhatsApp?

Yes.

Additional data may consume for background apps  & other processes (e.g – mostly initiate the application, notifications, etc..)

But data used from the relevant applications offered via Unlimited Blaster would be completely consumed from the Unlimited Blaster plan.

Since applications such as YouTube, Facebook, WhatsApp depend on several other background processes as well, it is recommended to have a positive data balance to support the same.
