Hi All

 

i am very new to this I have bought a simple usb SIM card reader of the internet and some blank cards. I have installed the SIM card reader and windows says it’s there but when I open the software it says it’s not present this is the software that came with it and the divers I have tried it on a windows 7 pc and it shows me the com port open and what it is and when I open the program to copy the SIM card it says insert card or reader both are inserted and I am going out of my mi d with this. Any help would be appreciated. I am doing this as an experiment for my sons as I think one of them has already had it done to him and it was very costly on his bill indeed. 

thanks in advance

In general, you better ask the manufacturer.  Perhaps they have a support forum?

As it's not a forensic tool, you may not get any answers. You will have somewhat better chances if you state the make of the equipment, and perhaps also the software.  That way it's at least theoretically possible to say if you can do what you want to do with it.

Again, in general, it sounds as if you have something old designed for COM ports, retrofitted to USB by some kind of COM-over-USB emulator. I've seen that with GPS devices and SIM readers, and never had much luck with them, as they often seem to require COM ports to be enabled and related interrupts to be free. A bit to messy for my mind.

 

Questions about cloning SIM cards are probably easier to get answers to, though.

Agree with @athulin observations.

 

Some historical background discussion that may help.

Historical issues might be useful to note BUT I suspect if you discussed with one of the forensic suite tool providers out there about how their tool produce 'cloned' evidential SIM Cards they might point you in the right direction.

As an observations, if you are discussing cloning SIM Cards are you stating or perhaps, through conjecture, implying one of your sons handed over their SIM Card to another person who then copied it or that someone stole the SIM Card and your son didn't notice it had been taken?

I am not saying this is what has happened, but it could be inevitabilty people may think that is what you are saying.

In the alternative, could the subscription mobile network operator assist by identify the local cell sites (Masts/Towers) and show the calls are 'inconsistent' with the local cell sites used where your son make his mobile phone calls (i.e. calls made in New York at 21hrs00 are then made in Texas 21hrs05)?

You may wish to read this article (and there are many out there on the internet) https://securityintelligence.com/posts/clone-or-swap-sim-card-vulnerabilities-to-reckon-with/

Lastly, you mentioned "costly". It doesn't automatically follow that the SIM Card has been tampered with or suffered from SIM Swapping etc. Spyware and auto-rediallers can be downloaded on to most modern smartphones when visiting particular websites that are less than honest. Checking the billing to define the difference between phone calls made and data-plan usage could be another option you may wish to consider.
