I very much operate within the Apple ecosystem, so I will not pretend to be an expert on Google... That said, yes, I also send SMS messages via my laptop... but that laptop leverages a bluetooth connection to my iPhone, which in turn leverages the cellular carrier. I stand by what I wrote as a general rule: Sending or receiving an SMS requires the cellular carrier's messaging infrastructure.
Let's not even get into SMS gateways in general...
Let's do. SMS gateways one way or another end up connecting to the cellular carrier's messaging infrastructure. If AC wanted to, it could probably enable such traffic fro specific gateways... but it has (wisely) chosen not to.
Or the fact that basically every cell provider allows calls/SMS over wifi, which definitely works at 35k feet with the cellular radio off.
I think you missed this in my post:
