I have a Samsung gt-c3300k, it was given to me by my mother, but i have an orange sim card and it's an o2 phone. She gave me the phone because she got a phone upgrade on her contract. Is there anyway to get the network unlocking code without having to pay money.

Try 0000 or ask the one who had enabled the sim lock setting...if you want to try different codes then keep in mind do enter wrong cone consecutively thee times it will you puk number or in some case the device it self

Hello, You need unlock code to use it with O2. If your device is now out of contact you can Orange for the unlock code or else you need a third party unlocking website to provide the unlock code. The unlock code unlocking is permanent so you can use any SIM card in future.

Hi i think your Samsung c3300k mobile is locked to some other network provider due to this it wont accept your sim card .To solve this you must unlock it .Code are the best solution to unlock it .To purchase code visit Mobile-unlocker.com here they ask you the network name to which your mobile is locked and the IMEI number of your mobile .Then at last they deliver you code to unlock your mobile .Once your mobile is unlocked then it will be free to all network sim in it.

SAMSUNG C3300K and SAMSUNG C3300K Champ both are same,you can unlock it simply using the unlock code,get the unlock code from the site Superunlockcodes.com and unlock it from Network lock,then use with any GSM Network Sim card.

Yes
Rmove your SIM CARD then turn your mobile on
And type the code below on your mobile screen :
*2767*3855#
This code will make hard reset for your mobile and erase all passwords.

well, my old phone was the Samsung Soul U900, and axidentally put a Puk lock on that, and my dad rung up Orange, and asked for the Puk Code, and they gave us it and you just type into your phone the number you were given and it should unlock, obviously, you wouldn't ring orange unless orange is your network, so just ring the network that you have.
Hope I helped :) xx

My local shop in town unlcoked my pixon from o2 -> orange for £10 with a cable, i guess if you google how to this yourlsef you could save the tenner

i phoned orange and they where very helpful they told me to take sim card out and read out number on the sim card 10 secondons later they gave me a code for that sim card (which can only be used twice before a new sim card card can be issued ) this u locked my phone
