where is my puk code on my sim card

PUK stands for Personal Unblocking Key/Unlock Key in SIM cards, 3GPP cards, and Mobile phones. Sometimes it is also called personal Unblocking Code (PUC). It is used to reset the PIN (personal identification number) if the user has forgotten it. PUK code is also required if you want to switch your network provider without changing your number (sim portability). In this blog, we'll discuss InrQH.
