Stupid M1 sent me a message to restart my phone. And when I restart my phone, I am required to type in my pin code.
As I don't remember what is it, I just try my luck for 3 times. And TADA! It is "PUK" locked.
Only way to solve it was to call up the subscriber for the code. My dad not in Singapore that day.
And today, I called him and he took the puk code for me. Now my phone has regained it's normality again!
However, I didn't feel VERY upset over the phone because it's just the time for me to play...
