And that differs from the Junk text messaging I’m getting from my mobile phone carrier because?
Criminals can empty your bank account now by hacking your SIM or they can make your phone bill reach millions of dollars. Which is why my mobile phone is for making phone calls and I only use prepaid cards, so my tinfoil hat is working good so far. This is OK when your phone has a removable back and battery - you just pop the SIM card out and flip it over, but what if your SIM is a microSIM, stuck in a tray, fixed into an iPhone?
The obvious solution might be to call another phone, but if the device has no service or the service has been disconnected, don’t despair. Subscribe to the OSXDaily newsletter to get more of our great Apple tips, tricks, and important news delivered to your inbox!
A friend asked me about this after finding an iPhone, figured it would make for a good article for those not familiar. When someone answers just tell them you found the phone, you can guarantee that someone on that list knows how to find the owner and will get ahold of them. No idea what my number is, I change my network every couple of months, depending on what country I’m in and the best deal, and one rarely has to read out a number these days (you just send a group text) so I might have never actually read my number, myself. Of the seven billion modern SIM cards in circulation, hundreds of millions are estimated to be susceptible. With root access, these malicious apps could then obtain any data stored on your SIM, including your address book, or sensitive banking details stored by mobile payment apps. I always thought they were cheap, dumb memory in the order of a few megabytes to store basic data on. Another option would be to just start calling the lost owners contacts for obvious relationships, like moms, dads, grandparents, but that may be a bit intrusive. The hacks allow a would-be attacker to infect your SIM with a virus that sends premium text messages, or records your phone calls — and, in some cases, access the secure, sandboxed details stored on your SIM by mobile payment apps, giving a hacker access to your bank and credit card details.
Anyway, if you have found someone elses iPhone, be a good citizen and try to track down the rightful owner, they’ll appreciate it!
Enrique OrtizAccording to Nohl, he estimates that out of 100 mobile phones, he could gain root access to the SIM card on 13 of them.

In actuality, the SIM card in your phone is actually a small computer, with memory, a processor, and even an operating system.
The number will be printed on the SIM card itself but is very small, especially on the nano- and micro-SIMs used in newer iPhones.
As you can see in the diagram below, there is a chip beneath those gold contacts, and on that chip there is a processor, ROM (firmware that stores the OS and SIM apps), EEPROM (which stores your phone book, settings, patches), and RAM (for use by the SIM’s OS and apps). How to find your SIM card number on an iPhone running iOS6 To find your SIM card number, from the homescreen: Tap Settings. In this case, modern SIM cards run a very simple OS that loads up Java Card — a version of the Java virtual machine for smart cards (of which SIMs are a variety of). Java Card essentially runs small Java applets, and each applet is encapsulated and firewalled (sandboxed) by the Java VM, preventing sensitive data from leaking to other apps. Your phone interacts with these apps via the SIM Application Toolkit (STK) to display information on your screen, and to interact with the outside world. To load apps onto the SIM or to update them, hidden text messages are sent by the carrier, containing over-the-air (OTA) programming in binary form. These messages are signed with a cryptographic key, so that the SIM knows that these messages have originated from a trusted source.Now, German security researcher Karsten Nohl has discovered a way of finding out that all-important cryptographic key. By sending his own OTA SMSes that aren’t signed with the correct key, he discovered that some phones pop up an error message that contains a cryptographic signature. Once he had this key, he could send apps and viruses to the SIM card that can send premium text messages (racking up huge bills), re-route or record calls, collect location data — you name it, with access to the SIM, you can do just about anything.
