Now check your IMS status in * # * # 4636 * # * #
under the IMS menu it should say registered or not.
You won't see other indication if VoLTE is enabled.
Or, if VoWiFi is working, you can connect to WiFi and try
to make a call while on airplane mode. Another indication
that IMS is working but not really related to VoLTE.
Or, switch to 5G/LTE only and make a call. If it works,
it's doing so over LTE.
