Plans for VOLTE on ROG Phone II
So, I am one of those ROG Phone II owners (global version) and go figure, I do not have VOLTE on my phone as well. I've been reading up some posts and forums in regards to VOLTE. What I get from it all is that the option for VOLTE requires both parties (carrier and and phone software) to fulfill certain criteria and ASUS apparently have to get confirmation from carriers so that VOLTE can function. So here's the thing, I know that the ROG Phone II is capable of VOLTE. But I am not sure whether the feature is enabled or disabled in the ROM or its just that my carrier is not sending the information required (IMS registration) for VOLTE to be enabled on my phone.
One thing is for certain is that I know my carrier has VOLTE. So which is it? ROM side or Carrier side that needs to enable whether that needs to be enabled for it to work?
I have read someone actually succeeded in enabling VOLTE by forcefully enabling it (editing system level file and ADB sideload). Obviously doing so voids warranty but this also tells me that ASUS colud actually just enable the feature and that would be up to respective carriers' to support this feature. Can ASUS simply just leave VOLTE option on then?
