Airtel- Vodafone Volte issue

I am facing the Volte issue in my ZenPhone Max Pro M1 :

1) It was working previously but after new update it is not working

2) I checked with my service provider and also tried different service provider still the same issue.

3) No option on phone for Volte to Enable



  • This is a feature of asus max phones. They don't charge for it, it comes free with the devices.
