The tray that your Sim card sits in should have your product code in it.

have a semalhante, need urgent update ...

What code is it asking for?

anyway,
NOKIA LUMIA 800 : Existing device hardware version/s: RM-801 ("global") & RM-819 (Latin Americas) >>> If you are from Vietnam, you should use RM-801.

If you have used wrong firmware variant don't worry, follow case 1


Case 1: If it is asking for a 25-digit code, broken down to 5 boxes, it is easy to get it. You can obtain it from Microsoft HERE

Case 2:

Install Nokia Care Suit.
Connect your phone to PC and launch the NCS.
Check the phone details there. You should get the variant code as well.

Use this variant; this should work fine.​

Case 3: If your phone is carrier locked, use NSS PRO to unlock SIM.

1. Connect Phone to PC.
2. Start NSS PRO and use SIMLOCKS > WP7 > UNLOCK

This should do the trick, and you can use any SIM on your LUMIA phone.​
