How to unlock phones?

Hi, the procedure is really very simple. You just have to go Rio mobile customer care service centre and you have to tell them about your current service provider. You will have to fill a form which includes the information about your mobile, your network connection you are contracted with and the name of the provider you want your phone to get contracted. Also I want to make clear that you will have to pay some bucks to unlock your phone and unlocking charges vary from Company to company. It may take two to three hours and till then you have to give your mobile phone to the customer centre and they will enter a code. After some time, you will have a phone without contract and can use to whichever network you want to use in. Thanks
