I need to know the PUK2 code but have no booklets with phone

Hello
PUK2 are series of numbers that you need to use in case the PIN and PIN2 of your SIM card is blocked.In most cases, your operator or service provider is the best source of assistance with PIN and PUK codes. If the PIN code is entered incorrectly multiple times, your phone may request a PUK (Personal Unblocking Key) code. The PUK code is an 8-digit code provided by your operator or service provider. If the PIN2 code is entered incorrectly multiple times, your phone may request a PUK2 code also provided by your operator or service provider.
Hope this helps
