I have an ROG phone II on AT&T, and as of March 1st I can no longer make any phone calls. I have the latest update installed, 18.0210.2201.211, which I had to do manually because the FOTA service never works properly. I know I can root my phone and use the workaround, but I'd prefer not backing up all my data to unlock the bootloader and root my phone. This phone came out October 2019, and I bought mine in March of 2020. Any guidance on if or when there will be official support? AT&T locks my SIM when I remove it now since it's not on the VoLTE list they have. My sim is from my iPhone 5s, around 2013, so that may also be an issue. Data still works perfectly fine.
