SIM Card PIN and SIM PUK Code
In case you're wondering what the SIM Card PIN and PUK code do on your OPPO phone, it is an added layer for your data security, most especially for those saved on your SIM Card. Refer to the following detailed guide for a more detailed explanation.
PIN (Personal Identification Number)
A PIN is a 4-8 digit passcode used to authenticate a user to a unique system. PINs are often used in SIM or ATM cards. The phone's PIN is a storage unit inside the SIM card, and it is also a security measure to protect the SIM card from being stolen. If the "PIN Security function" is supported by your phone and is in "activate mode," then you would need to enter the PIN to unlock your SIM card each time you start your phone. In case both PIN and the lock screen password are enabled on the handset, then you need to enter PIN first, followed by the lock screen password to unlock your phone. The telecom operator provides the PIN, which can be reset and modified.
PUK (Personal Identification Number Unlock Key)
PUK is also called PUC (Pin Unlock Code). PUK is a string of eight irregular numbers which cannot be reset or modified by users. It only changes when the SIM card is replaced. PUK is used to unlock the PIN and some PUK's come along with the SIM cards.
