Right away, I'm not looking for ways to intercept sms/text or calls. But my questions does have something to do with it. To make long story short, a friend on mine who's not very tech savvy, asked me to look into ways to tell if his Iphone sms and/or calls being intercepted. If it was a PC I wouldn't have any problems as I would to a sweep and monitor network activities and such, but when it comes to iphone I'm really at the loss.
So my question is, are there any tools to see if his SIM card was duplicated somehow (the only way I'm thinking it could have happened through blue tooth, maybe, as no one had physical access to his phone)? Which brings me to the question, can the SIM card be duplicated and used in another device to "silently" listen and/or view incoming texts and call logs? If the answer is yes to any of the above, any help as far as where I can purchase proper tools to do diagnostics and prevent this heppening and what is the security situation for the Iphones in regards to intercepting calls/text, would be greatly appreciated.
He has Iphone4, it's not jailbroken.
Thanks in advance.
