Unlock PIN on a new SIM card inserted in my smartphone
Unlock PIN (Personal Identification Number)
PIN is set to prevent unauthorized user to access your SIM.
If your device locks when used with a SIM card and requesting for PIN code, simply insert your PIN code to unlock your SIM card.
A new SIM card usually comes with a temporary default PIN of 0123 or 1234.
SIM card will be blocked if you enter incorrect PIN code for 3 times.
Once SIM has been blocked, it will request for PUK code.
If you does not have your PIN / PUK code, you have to contact your Mobile Network Operators (Telcos) to obtain your PIN / PUK code.
