Its not blocked its locked - there is a way to unlock it. Change the Phone ID with software called Nemesis service suite. Change to generic N73 PID then upgrade software via nokia site - ddebranded and siorted!!

Nokia n73 doesnot on if i insert sim card

i have a friend almost has the same problem as yours with N73, and when it turns on it wont even send a single message. try cleaning up the sim slot and the sim card itself, and if this doesn't work you'll need to take your phone to the nearest nokia service center. (please vote for me)

Lock code error

It seems your phone is blocked. Take the phone to your nearest shop that deals with your air time, ie O2, T-Mobil etc. They should be able to unblock the phone for you. They may have to send the phone to the manufacturers which should take no more than fourteen days, and there maybe a charge for this service.

Try..Try N Try

Now your sim card needs PUK number. If it is sim lock then Please contact your service provider and ask for the code. If it is phone lock then you need to reload the software for your phone. But this will erases the data on your mobile. Or click on the below link or copy the URL and paste it in your web browser. And follow the steps.

Thank you......
