That's easy to fix. Remove those from the GPRS status.

That is not possible either to our understanding. If it were possible, the ISI modems would expose that data separately, which they don't.

That is different. If you are outside of coverage, or in a non-GPRS area, you can turn auto-attach on. That will make some operators happy but it wont't attach just yet.

Whether it makes practical sense, I dunno. Operators ask for this. Maybe there is a reason (maybe not).
