How to get VoLTE/VoWIFI of 9RT to work on T-mobile or Verizon (Visible)?
Actually, 9RT doesn't work on Verizon (Visible) at all.
Thank you!

I will wait for a few more days for solution until I give up 9RT and buy a Samsung S22 series.
OnePlus phones are no longer useful, at least dual sim models for U.S. users.
