Where is my caller ID option on my Windows phone after the Denim update?

[Windows Central Question]

I am not having caller id option in my windows phone denim update.

All my network+ app and extras is updated to latest, and still no caller id option. As a result i cannot use the "Live caller id" feature of truecaller. I have a NOKIA LUMIA 1020 with a carrier "IDEA CELLULAR" in INDIA.
