Hi @Nerosx9 
VoLTE is by standard in the ROG Phones, but it's dependent on the service provider. I would recommend checking with them if VoLTE on the ROG Phone 7 is activated on their network.

Which service provider are you using?

Thanks for your feedback. I am using VINAPHONE service and am contacting them to discuss this issue.
