Do you need to change your PIN code for added security or because you’re having trouble remembering the current one? Don’t worry, changing it on Apple smartphones is very straightforward. In this guide, we will explain step by step how to modify your iPhone’s PIN code.
The PIN code (Personal Identification Number) is a key security feature for all smartphones, particularly for iPhones. It protects access to your SIM card, preventing unauthorized users from accessing your information if your device is lost or stolen. Therefore, it is crucial to have a strong code and to change the default code (often 0000) that some operators provide.
Furthermore, it is advisable to change it frequently. Before diving into the details, remember that your phone code is a distinct element and unrelated to it. In this tutorial, we will explain how to change, deactivate, or reactivate the PIN code of your iPhone. The method described is valid regardless of the iOS version you are using.

🤔 What to do if I forgot my PIN code?
If you have forgotten your PIN code, be aware that your SIM card will be automatically locked after three incorrect attempts. It’s best to be cautious in this scenario.

Additionally, note that after ten incorrect attempts, the SIM card will be permanently locked.
