I thought I already solved this problem. There is no phone number associated with the sim. The company that issues the sim is very integrated with the GSM network and the system doesn't work the way we expect it to because it doesn't have to.
As I already posted in the third post 882-35 is the international network number for Jasper Systems, inc, which happens to partner with AT&T and (assumingly) is the company providing the network access.
It does sound like the number is the MSISDN, which probably means there isn't "phone number" attached to it as they access it directly by the MSISDN at the BSC/MSC level...something our mobile phones are not expecting (they expect a phone number).
