Hello
When setting sim to 4g only i am unable to make and revive calls. Upon changing to any other option (4g, 5g) calls come in and I can dial out again. I've just installed yesterday after receiving pixle 6a. Build TQ2A.230305.008.E1.2023032600
Thanks
Please ensure that VoLTE is enabled in Settings | Network and Internet | SIMs | VoLTE.
In LTE-only mode you can't make calls w/o VoLTE provisioned and enabled. More, see here - https://discuss.grapheneos.org/d/4025-setting-to-lte-or-lte-only-blocks-phone-calls/3
I see, thank you. I don't have that option in settings. Does that mean the carrier doesn't support it?
My carrier and plan support VoLTE - do I have to enable it in developing settings or else where?

Honestly, I'm not so sure. I got this toggle option after the last update 2023032600. I saw it in its changelog, too - https://grapheneos.org/releases#2023032600.
My operator is currently transitioning to 4G/LTE and this option was missing before the update to 2023032600. However, I was in 3G but yesterday I did some tests with LTE-only and discovered I have VoLTE already. Not sure when I was migrated.
A couple of months ago my phone was switching from 4G to 3G when receiving/making calls. Now with VoLTE enabled it stays on 4G/LTE during voice calls.
Oggyo thank you for your help
