I have several 1841s with 3G HWICs. They are connected fine and have been running services at the roadside for a couple of years. Does anyone know of a way I can find out the sim number of the attached sim without going out onsite and powering off the kit and physically looking ( i need either the normal dialling number or the 24 digit number printed on the sim). Is there a command within IOS to see what the own number is much like the way you can on a vodafone mobile by dialling *#100# or force the HWIC to send out an SMS or force it to dial another number (without the connection irrevocably dropping)
So far I've not got anywhere with this, but if anyone knows, then please let me know.
