More than likely not due to the Telus grey market device policy. I tried my 8T+ 5G from T-Mobile with a friend's SIM on Sunday and could not get VoLTE provisioned, even after using an app to toggle it on without being provisioned. This device worked for two years on Telus before it was deprovisioned and I was told it was due to the grey market device policy. When I upgraded to an s23 Ultra from T-Mobile USA, I was told the same thing by a Telus Senior Network Engineer after providing them my device IMEI's.
