I've got an embedded system that uses a Nokia 6081.
I need it to know when the phone is able to call (ie. is registered to a network operator).
How could I do this?
I can send AT commands to it through a Psion GSM GoldCard, but none of the ones I could think of (+creg, +cops, +csq,...) did work.
Obviously this is not a really easy question, but if someone could indicate a better place or person to ask, it would grately appreciated.
