There were only two posts on the thread that you linked, and neither one really addressed my question. You just explained how to turn off EVDO once it's on and connected. That's too late for me.

Thanks for your input, though.

I want to know about how heavily MMS relies on the data network, and if turning all the connections to WORK makes the MMS unable to connect to data. I've already concluded that completely deleting the #777 BBA account will put a halt to all data communications, including MMS.
