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)

Sim card not vaild

If the sim isnt accepted, that means that the phone is locked to t-mobile by the provider which she originally bought the phone from

The phone can usually be unlocked directly by T-mobile and would be worth a try to call T-mobile and provide them with the IMEI number of the phone (press *#06#) and get a unlock code from them.

Hope this helps

Look, your phone don't recognize the card try to put another card, if it won't help clean the place of the sim card with a tooth brush its probably dirt.

Forgot my lock code for N73

you need to have a master reset code to reset all the settings. I do have an unlocker for this. if you want just give me the IMEI code and I could process it for you FREE.
