Normally pin code would be 0000 (4 zeros) if you haven't change it. DON'T input pin code more than 3 times cos your phone will be locked up if those codes were wrong. But it's just a tricky way to solve your problem.... input wrong pin code to get your phone locked then ask your network provider for pin2 code or puk code to unlock your phone, now you can use a new pin code as your liking.
