Heads is good reference for what could be done at BIOS level. It can connect via ethernet but only because the firmware is built in (The GBE section in IFD stands for Gigabit Ethernet). If you want an SSH server, this needs to be built separately because Dropbear is too big to include by default. Due to the size of firmware and range of different wifi cards that could be installed plus the software to connect, wifi is not possible in Heads. Similarly with Bluetooth. For cellar, the firmware, software and configuration would be needed to BIOS. There is also how no service/roaming would be indicated without any physical meter like LEDs (Ethernet has LEDs to show connection). It would also take time during the boot cycle to connect to a cellular service and would block booting the OS. That said, you could add a service at boot of your OS to do this and connect to something like a NextCloud Phone Tracker to do this.
