For voLTE, yes. But on the phone, they will insist it's your phone issue if you can't get voLTE, you need to convince them to submit request for voLTE activation. This is my experience for a few times using Hotlink and Maxis, last was a year back. Not sure if now, it's auto or not.

For voWIFI, I not sure

How to know voLTE enabled/used? Can see on the phone, got voLTE symbols.. but if don't have, try to make calls and see if it stays on 4G or goes to 2G.

That means got voLTE

Last update.. June 2024. I ported to Hotlink again.

Once new SIM activated, don't have voLTE

After check with CS, then only voLTE started working.
