hey i am having a problem here. i need help. i tried to put my fido sim card in a locked bell phone, and it asked for a pin. i tried 2 times with different pins and failed, so i took out the sim card. I put the sim card back into my regular fido phone (sony ericsson vivaz pro), and when i turn it on, it is still asking for the pin. I have 2 attempts left, and wish to not destroy or ruin my sim card. I need help because im not sure what pin to put in, do i put in my PUK? or my regular PIN to get in?
