Unable to Add Call

I have several other Android phones not purchased from T-Mobile and they all have worked fine. Only difference is that the S22 has Android 12.
But are those other Android phones US or international variants/models, i.e. imports? I'm thinking this "Add Call" or "Merge Call" functions is proprietary to T-Mobile and is US only, which international variant phones may not support.
It's something I've never seen from carriers either in UK, Ireland, or China. And the nearest thing I know is conference call..
