VoLTE feature is not available on my iPhone 8 Plus

If I get you well, then all iPhone 8 Plus with model number A1864 should not support VoLTE

I said that feature is enabled in MTN network in the last quarter of 2019 and that’s the reason for this discussion.

i even enabled for one lady

The carrier service is supporting that feature.

I think iPhone 8 Plus should support but mine with Model A1864 is not.

That's my concern I needed assistance
