How to unlock Nokia 5530 phone?

I think I can solve your problem buddy. Recently when my friend bought a Nokia phone and was facing the same trouble with security lock code, he fixed it quite easily. As I said that don’t worry much about it so it you can fix it yourself. So I must tell you that you cannot reset such security code at your own and the only way to unlock is to service your phone from Nokia care or from any retailer if they have sufficient knowledge. But, most of them don’t have any idea about unlocking phone and those who know they usually charge $2 for unlocking normal phones. So I will not recommend you to contact a retailer instead. You can ask your operator for Personal Unblocking Key and if it will not work then ask for IMEI code and it will help you to fix it same time. So take my advice and contact your customer care as soon as possible. I am sure this much info is sufficient for your problem. Good luck buddy.
