More referring to selling a device classified as a mobile phone that might not be able to connect to emergency services without any tinkering. My google-fu is failing me now, but I’m trying to see what the actual requirements are, if they exist at all, to sell a mobile phone. All I’m seeing is that the radio shall connect to any available base stations during an emergency call regardless of subscriber status.

I don’t know how the linux phone OS’s are handling these kind of interactions with their baseband processing, if at all.
