Is your Nokia N73 locked with any particular network?If so when you try to insert other network sim cards you will get the error "Sim not valid" or "Sim invalid" or "Sim not supported". Try to unlock the mobile.I suggest you can approach Theunlockarena.com and specify the country,locked network.Based on the availability you can get the unlock code along with free instructions. http://www.theunlockarena.com/nokia-n73/rs13wp9/
