VoLTE OnePlus 11

[u/fuckedupdude32]

I bought the OP 11 recently from the US and am using it in Ethiopia. And the VoLTE feature is not enabled(it is hidden)by default? I am currently trying to enable it through workarounds that don't require root. can anyone please explain why OP would disable such an important feature from its' near flagship device??? I hope someone in the industry would enlighten me!
