Nokia rm162 is asking for a ristriction code, may i have one please

There can be many ways to Unlock your phone. As far as i know unlocking by codes is the simple and safe way. I will suggest the website http://www.unlock-zone.com/ which is doing good service and they were recommended highly in the cell phone forums.
I used them to unlock my cell phone. contacted them and within 30 mins i had my unlock code and my phone was unlocked.
Hope this helps.
