Hi, seems like I had to use Shizuku and Pixel IMS to get it working, also had to make some APN modifications to get MMS properly working. All good at the moment though.
Hey, thanks for the post! Out of curiosity, now that it's been a few months is VoLTE still working for you on your Oneplus 11? And what oxygen os update build are you running? Not sure if I should update to CPH2451_14.0.0.833 lol.
