If I hand dial the cell, I get a modem-seek noise, but it takes a minute to do, so it is not a bad phone number. I am getting four bars for signal strength (and of course on their software, every time I hook right up, and the cell phone’s Data Usage screen logs it.)

Is this engineering on the part of the phone people to ensure they get paid? Has anyone done what I am trying to do successfully?

You are trying to modulate digital data into audio. Your phone then converts it back into digital data, using rules designed to handle voice. The process is reversed at the other end.

Cell systems are designed to use minimal bandwidth to transmit VOICE audio. It's not designed for the audio tones used by telephone modems.

And on top of all that, I'm not sure that your Bluetooth connection isn't trying to make a digital connection after all. And AT&T has explicitly disabled that, unless you pay for what they call "tethering".
