I don't think VoLTE uses anywhere close to this level of data. I saw somewhere that video calls over LTE (which DO get charged as data) use a few (maybe 4 or 5) MB per minute. So it would take 3 hours of video calls to use 1GB. And I guarantee you that VoLTE audio only calls use only a fraction of that amount.hmmm I have a co-worker who has a ip6 and he recently turned on the option that allows voice & data at the same time and he is burning through his data he is already at 7gb+ only 1/3 way through billing cycle.
