Answer :
Final answer:
The code to reset a forgotten PIN is the Personal Unblocking Key (PUK), unique to your SIM card, and provided by the mobile network operator.
Explanation:
The code used to reset a forgotten PIN is called the Personal Unblocking Key (PUK). This code is unique to your Subscriber Identity Module (SIM) card and is required when you have entered your PIN incorrectly more than three times. Your mobile network operator can provide you with your PUK code, which can then be used to reset your PIN and regain access to your SIM card. It is not the Home Location Register (HLR), Electronic Serial Number (ESN), or the SIM that can reset a forgotten PIN directly, but specifically the PUK code.
