Pin number
If you have lost your pin number, the only way to rest the PIN is either using a different SIM card, or entering wrong PIN three times, triggering in PUK code, and then calling SIM card phone company to unlock the PUK.
A lost PIN cannot be retrieved, only the PUK can be discoverd, but you will have to call the phone company.
PUK means "personal unlocking key" .
The PUK code is asked if you enter a wrong pin 3 times.
You need to call the phone company that released the SIM card, they can retrieve the PUK code from a database for free.
In your case you need to contact your SIM card provider technical support to unlock the SIM.
The
SIM card provider is the brand on the SIM card. For example if you have
a Vodafone card, you will need to call Vodafone to get the PUK.
The PIN and PUK are related to the SIM card, not to the phone.
If you replace the SIM card with a different one, then the phone will not ask for the PUK anymore.
