How can I read the SIM number?


I currently must roll out over 50+ computers each with their unique User/pass for the cellular network.

These user/pass combos are unique to each sim and my idea is that I want to automate the install process much due to the PC's will see around 2 reinstalls in their lifetime, so I dont want to type this info in 150+ times.

I've already tried to export the profile off the software, the user/pass is cleartext so it should be straight forward to import new profiles if I am able to read the SIM number off the computer.

The specs are as following:
Fujitsu Siemens LifeBook T5010
Windows XP Tablet Edition
Sierra Wireless HSPA Network Adapter (MC8790)
Sierra 3G Watcher build 1822.

I am able to extract the IMEI of the WWAN adapter from the registry, but I am not able to extract the SIM number which is what is relevant. I have also had a look around the WMI info without being more clever.

Any idea's on how I might accomplish this?

By the SIM Number do you mean the long number printed on the SIM Card, or the actual phone number associated with that SIM?

The first should be possible, but the latter certainly isn't. This is because the phone number isn't stored on the SIM Card, but is related the SIM Number (long number printed on the SIM Card) by the network provider.

Hello again,

I've researched a bit more. According to the manufacturer of the chip it should be possible to talk with the chip using the COM interface.

However I am unable to do this, because I get the Portsettings wrong. Are there anyone who knows HyperTerminal and can help me with talking with my modem to get the command AT+CIMI sent to the modem from there?
