VoLTE not working

Xian W.

Hi everyone. I switched the sim card for VoLTE months ago, today I got mail from Fizz says "Your SIM card switch is done, nice", with 5G perks.

Does it mean that VoLTE is now functioning on my iPhone 12 mini? I restarted and tried twice today, still shows 3G when calling.

Anyone? thanks.
