A new bug has been found in Apple’s iOS platform which allows any device to be factory unlocked to any network by using an R-SIM and directly modifying the ICCID. The device will then continue to work, without the R-SIM, using any network’s SIM card.
iPhone and iPad owners are used to hearing about iOS bugs but are also used to them being discovered by security researchers and used for the purposes of trying to find a route into the device for jailbreak purposes.
It’s rare – at least in the modern world of iOS – to have a bug discovered that is uniquely related to unlocking the device and ensuring that a factory locked iPhone can be used with any network without having to request Apple or the locked carrier to interject. However, with the right tool, and with the right process, that’s exactly what we appear to have here.
The process of unlocking the device by changing the R-SIM ICCID has been shared on the Internet and has since been picked up and shared profusely on various outlets. It won’t be long until Apple gets wind of this issue – if the company hasn’t already – and puts fixes in place to prevent it from happening.
The process appears to be as follows:
Note: You will of course initially need R-SIM for this to work. You can get it from here.
- Insert a unsupported SIM with the R-SIM into a locked iPhone
- Type *5005*7672*99# and then tap edit ICCID
- Type 8901-4104-2778-0604-3133
- Restart the device and follow the setup
- Once back at Home screen, remove the R-SIM and just use the previously unsupported SIM card
And voila! There you have it. By changing the ICCID, it leverages a bug in the iOS system and actually unlocks the device for use with any SIM card. It is being pointed out that this isn’t entirely permanent and will be put back to being a factory locked device if a hard reboot or reset is performed on the device.
However, you can go through the process of an over-the-air (OTA) firmware update without the unlock being taken aware. However, if you do a full restore through iTunes, then the unlock is removed and the hard work is undone, so to speak. If you have a device that needs unlocking and you have access to an R-SIM, then it’s worth giving it a try.
