Hello, My daughter was playing around with the settings on her Iphone 4S and it asked her to enter the Sim card PIN. She entered her Iphone login PIN and it locked her out. Now the phone won't call or text with the Sim Card installed. But it does call and text with the Sim Card removed. How do we reset the PIN on the Sim Card??? Thanks Fred
PUK is Pin unlock code and is a security lock code.I would suggest you to call Sprint Worldwide Care to unlock your sim card -888.226.7212.
