The carrier can still make a special exception to have call/text only plans but it gets implemented via TCP/IP using either mobile data or the Wi-Fi calling tunnel.

Google Messages does work on GrapheneOS but requires special configuration for at least some users due to the anti-spam checks and isn't guaranteed to keep working due to it being a Google service in practice where they could add Play Integrity, etc.
