I am a a SIM farmer. I buy and sell sims by the 100's. One of the things I look for when I buy sims
(I call it harvesting) is that occasionally there will be an active sim with a working number,
these can be sold and are worth quite a bit more than an inactive SIM. At
any rate, I am looking for a device that can read the actual phone number
connected to the sim, I need this in order to sell the sim. For at&t, and
Tmobile this is easy if you have a phone running on that network. But often
I get sims from outside the US and and can tell that they are still active
but can not determine the number associated with the sim in the regular way. If you have any
insight into this or can point me in the right direction that would be a
great help. I prefer this to be a stand alone hand held device, but realize that what I am looking for will
probably be usb based and need to be connected to a computer. If this is the case as there a OSX version?
Thanks for your time. I appreciate it.
