I want to unlock my handset and switch over pre paid connection. If you know the process of unlocking a handset, please help me. I am availing AT&T network and I have got a password from them fot unlocking the handset, but still, I am unable to go through the whole process of how to unlock a cell phone. I am using Samsung A177, if anyone has tried to unlock the handset, please share. It would be very grateful to you. I thank you in advance for your valuable suggestion.
