Please call the Customer Care of your Network Operator (sim card provider), they will tell your the code. There's no other way or no means to get the code except from the Service Operator. They might ask your few questions related to the Sim Card, like your name or your address, tell them promptly and they will give you the puk code for your sim card. It's also important to note down the Sim Card Number (number written on the sim card) if in case they ask you the sim number. You will also be assisted on how to disable the security settings.
Note: if you keep entering random/unknown numbers/codes, the sim card will be locked and will be rejected. It'll not be usable anymore. Good luck.
The "insert sim" error is a common error. Usually it is caused from putting the sim in incorrectly.
Try this. If this is the one with the sim card ports that are on top of eachother than put the sim card in the port closest to the phone with the gold side pointing up.
Insert battery, turn on phone.
On the phone, go to the main menu. Tap phone settings. Tap dual sim settings. Tap to open sim 2. Go back to the main screen.
If that does not resolve go back to phone settings, tap dual sim settings, tap to open sim 1, go back to the main screen.
If this is the type of phone with the sim card ports seperate, insert sim with gold side down in either port. Go to phone settings, tap dual sim settings, tap open dual sims. Go back to main screen.
If this problem persists than either the phone or the sim is defective. Test the sim by putting it in a phone that belongs to the carrier the sim came from. If it works in that phone it is not the sim.

Try typing #pwd# and then "send. It will reset your password to the the last 4 digits of your phone number. Then you can reset your password back to what ever one you can remember. credit given to jlh for this tip
hello, hope these instructions help:
1. To expose the SIM card slot, peel back the bumper from the top-left edge of the device. (fig 1)
2. Insert the SIM into the slot with the gold contacts facing forward and the cut corner facing out. (fig 2)
3. When you release the SIM, make sure it is locked into position behind the catch so it will not spring out.
4. Replace the bumper and turn on the device.
Any problems, let me know :) Si
