Using Your SIM Card's PIN When you receive your SIM card, you will be provided with a Personal Identification Number (PIN), a four-digit number used to verify the identity of a user for security purposes. Below are some tips to keep in mind regarding your SIM card's PIN: ⅷ You will be prompted to enter your PIN each time you power the phone on with the SIM card installed (whether or not your phone is in GSM mode). Keep your PIN handy. ⅷ If you enter an incorrect PIN three times in a row, your phone will lock itself and your PIN will no longer be accepted. You will be prompted to enter a PUK (Personal Unblocking Key) code. You will need to call Sprint PCS International Roaming Solutions from a landline phone to get the PUK code.
