Understanding SIM Card Number Check Codes and ICCID Numbers Effective SIM card management is becoming more and more important in the world of IoT (Internet of Things).

If you don't own an iPhone, Pixel, or Samsung, another way you can find your SIM card's ICCID number is by using the secret short codes for Android, particularly the Man-Machine Interface (MMI) code.

Depending on the mobile carrier or network provider, you may have a limited number of attempts to enter the correct PIN code before the SIM card becomes permanently blocked.
