I see enriched calling but not advanced what are you wanting to turn off

I can't access internet service while talking on the phone . It is a phone issue or app

Oh that would depend on carrier also can think of one that doesn't allow that only thing to check would be Hotspot if using that or data but that wouldn't stop a call by itself
