On my Pixel 7, I just flashed Graphene OS. It went fairly smoothly.
But I ran into a problem: The phone now does not support SMS or calls. Graphene OS Messenger displays "connection error 111" for me.
My SIM card worked flawlessly when I tried it on a different phone, so the issue is not with the card.
I attempted a restart.
I made an effort to clear the network cache and data.
Still, I am unable to activate Signal and perform many other random tasks without SMS.
Can anyone help me out, please? If not, I must turn to my "fiendly neighborhood stalker," Google.
