I need unlock code for orange to o2 samsung sgh g600

What unlock code did you mean? Samsung SGH G600 network unlock code? If that code is what you mention you can get that from your network provider in this case you can call o2 customer service and make request about samsung unlock code, they will need to know your account details to process your request. I hope my solution can help you.

If you are currently a customer of Orange. You can call and request unlock codes from that company for the phone. You can do like wize with other cell phone companies. Some companies will give you the codes on request. Others will hassel you, but more then likely they will walk you though it if you call them from a diffrent phone. So that you can use other companies service.

need puk code for samsung sgh g600

I have just tried it with my new locked to orange g600 and it works fine on all networks.

1-Turn on the phone without sim card .
2-Pull off the battery cover and insert any non-accepted sim card (without turning off the handset)
3-Do full reset *2767*3855# , phone will reboot and goes to Menu .
4-Customize Sp-lock code *7465625*638*00000000*00000000#
5-Unlock your phone with new SP code #7465625*638*00000000#
6-Enjoy G600 unlocked
if it doesn't work after step 3.. try changing the 'non-accepted' sim card that ur putting in..
eg if you are locked to vodafone and you try this method and use an orange sim card and it doesn't work, try using a o2 sim or even virgin :)
its easy good luck
