ok ive forgotten my password before and i looked online for my puk code and it worked. However, yesterday my little sister was trying to guess my PIN code and it locked on her - i was happy to let her try and guess because i was confident that i could find my PUK code on the O2 website. But i looked today and when i typed my phone number in it said that they didnt have a PUK code for this number! i did exactly what i did last time, my phone number hasnt changed - i even tried five more times and checked my number, but to no avail - and i dont knoww how i can gte my PUK code and unlock my phone!! Please help me, megan xx
