The process relies on a vulnerability in some phones—most notably older iPhones (iPhone 4 through iPhone X) and a limited number of Android devices. Here is the step-by-step:
If you still choose to explore ICCID unlocking – for example, while waiting for a cheaper official unlock – proceed with caution. Use only well‑known bypass cards, keep your data backed up, and never assume that a black‑unlocked device will stay unlocked forever. Your phone’s freedom from carrier restrictions should not come at the cost of its security or your peace of mind.

: This is not a brute-force or hacking method. It relies on configuration files (e.g., carrier or commcenter files on iPhones) or software that rewrites the SIM’s virtual profile.
Updating your phone’s operating system can break the hardware exploit, rendering your interposer chip useless.
The tool functions by tricking the iPhone into believing it has been authorized for use on any network. The Hardware

: The tool uses a thin chip placed under your SIM card to mimic a legitimate carrier handshake by using updated ICCID (Integrated Circuit Card Identifier) codes.
If you are looking for an ICCID unlock tool, you must be aware of their highly temporary nature. For years, Apple and major carriers have engaged in a continuous game of cat-and-mouse with the creators of these bypass chips.
No. The ICCID exploit is specific to Apple’s activation server architecture. Android phones use different unlock methods (bootloader, service codes, or paid remote unlocks).
It is crucial to distinguish this method from the "official" unlocking process. An official unlock—usually done through the carrier or a whitelisting service—registers the phone’s IMEI in a global database as "unlocked." This is a permanent status change that survives factory resets and software updates. The ICCID unlock tool, by contrast, is a transient bypass. It is often favored by users in regions where official unlocking is prohibitively expensive or unavailable, or for devices that have been blacklisted due to unpaid bills or insurance claims (though an ICCID bypass cannot circumvent a blacklist of the device IMEI, only the carrier lock). Your phone’s freedom from carrier restrictions should not
While instructions vary depending on the specific brand of the unlock chip (e.g., R-SIM 15 or R-SIM 17), the general methodology follows these steps:
Press "Send" or "Accept." Reboot the phone immediately.
: The tool prompts you to enter a 19-20 digit ICCID code.
The unlock lasts until you perform a "Factory Restore" via iTunes or wipe the "Activation Record." OTA updates, reboots, and SIM swaps are safe.
