Nokia 3200 security code HELP!

I have recently used a Nokia 3200 cell phone but have just got a new, better phone. But when I tried to use the Nokia with another SIM card, it asked for the security code. It only works with my old SIM card. I looked in the security settings section and found that the security level is set to phone. I must have set it by accident and forgot the code.

Can anyone please help me? I've seen another post on this forum with a similar situation that seems to have been resolved and thought maybe someone can help me like they did that guy.

Thank you.

Never mind, it is solved.

ok but... tell us how you've solved this problem..

I used the standard code: 12345. I'm an idiot.

But this site has great tools (I can't post links so just put the name together) http :// www . unlockme . co . uk /
