I forget my phone lock so how i can get phone lock, when it swich on it ask me phone lock.

Hi there, You may contact to your carrier service provider Samsung GT-C5212i Unlock Code, they can open up all networks for you where you want to use your phone. Once your phone is unlock, it will work with any networks worldwide without sticking to one network only. I suggest to visit Samsung Unlock Code site, they will provide you an accurate code with easy to follow instructions on how to unlock your phone.
Hope it helps.
