Imei no is 353203030349453. tell me restriction code plzzzzzzz.

If your Nokia mobile phone displays Phone Restricted with an Undo option and selecting Undo results in an Enter Restriction Code error, your Nokia mobile phone is Network Locked. This means your Nokia mobile phone has been restricted for use on one specific network and a Restriction Code or Unlock Code must be entered before the phone can be used with alternative networks.
You can get the restriction code at here Theunlockarena.com you need to specify the Network,country it locked,then get the code and Unlock it.

Well if you are tied to a particular network all you have to do is to unlock your phone to use it any other GSM network. You can get the unlock code through online. Give your IMEI number & get the unlock code for ur mobile .............You also get through online..........I will suggest the website superunlockcodes which is doing good service .....you can approach this website.
