    Re: 3220b I have got an IMIEI unlock and that worked. I popped in my existing SIM card no problem. I then put in a 3G SIM card from other smartphone which does work on my other same carrier older Nokia phones and then pop ups a prompt asking for a security code.

    What do I need to do?

    Standard security code on Nokia handsets is 12345. If that doesn't work whoever had the phone before you did changed it to something else. If you cannot get hold of them to tell you what the security code is there was a security code unlock site though I'm not sure what it is try this: Security Master-code calculator for Nokia mobile phones

    I'm the original owner, i never changed the code. I recall hearing a long time ago that the 3G SIM cards are not backward compatible with this phone/model. The 12345 doesnt work btw. The security unlocker link above does though! I appreciate you taking the time to reply. thanx!!! :)
