It's more than that. There's no reason for there to be any routes for
anything except phone to APN, and no reason for them to not filter out
all incoming requests and inter-phone traffic as a security measure.

You can't persuade your cable modem to let you talk directly to your
neighbor, either.

Even if you found cases that worked, with phones hopping from tower to
tower, and there being no reason for it to work as a matter of policy,
I don't think it's anything you could ever make robust and reliable.
