All phones can, and all networks in the US and EU at least are legally required to accept emergency calls from any phone, if it’s in their network or not, or if it has a simcard or not.
The SIM card only acts to identify you, it is not technically necessary to place any call
now that’s just not true, or at least can be made not true. There is no technical measure preventing someone from flashing a ROM that completely blocks 911 and other special numbers, or be like postmarketOS on quite a few phones and don’t support calls at all.

I wonder how it decides what network to use when the Sim is out.
Strongest network? Preferred network? Chooses the one that’s been the biggest bitch as a fuck you to them?
It probably uses the same logic as when you’re roaming out of your carrier’s area.
Roaming is usually a contractual thing. Like Sprint might always roam onto Telus in Canada.
These would be phones with nobody to have a contract with?
