Why am I being asked for my phone’s PUK or PUC number?
You have entered the wrong PIN more than three times
Your SIM card has been reported lost or stolen
Most phones permit only three attempts to insert the correct PUK number (PIN) and should we fail to do so the phone is programmed to automatically lock.
What happens if I continue to insert an invalid PIN?
Should the owner continue to repeatedly insert the WRONG pin number, and ten attempts is usually the maximum permitted, then the cellphone locks permanently and your SIM card may as well be thrown away.
How do I find the PUK number?
The PUC code or PUK key is found on the SIM certificate, which you get when you first connect to a wireless network. Entering the PUK number will bring back the original unlocked status of your cellular phone. The PUK can also be obtained from the network service operator (ie. AT&T, Vodafone, Rogers, Movistar, T-Mobile, etc.) after following the appropriate security measures.

How do I insert the PUK number into my wireless device?
The cellphone will prompt you to enter the PUK number (Personal Unblocking Key) when a blocked SIM card is inserted. If it does not then just reboot the phone. After you have entered the correct PUK code, you must set a new security PIN number.
What happens if I forget my new PIN?
Go back to square one; you HAVE to remember the PIN number or suffer the futility of inconvenience.
Is unlocking my PIN the same as Unlocking my Phone?
No. The commonly used term “unlocking my mobile phone” refers to a procedure that permits the user to substitute the SIM card with a SIM provided by an alternate Network (see Unlocking FAQ’s)
