An unlocked phone is programmed using an IMEI code and a SIM card.
For an unlocked cell phone to be programmed it needs a few things. First is a number called the IMEI code, which identifies individual phones. The second is a memory card from a network provider called the SIM card that connects a cell phone to the provider's network. With these things and the cooperation of the providers, an unlocked phone can be programmed to work with a new network.
Instructions
1. Request the IMEI code from the last network the cell phone was connected to. If it's uncertain which provider was last used, there are third-party sources online that will find the phone's IMEI code for a fee. Although, generally, it's cheaper and wiser to work directly with the network provider, although based on provisions of the phone's initial contract they could still charge for the code.
2. Remove the plate covering the phone's battery and make sure the phone has a SIM card. The slot for the SIM card can be found near the battery; it will be small enough to house a chip-sized memory card, or will actually have a memory card in it. If you are switching network providers, remove the card and insert the SIM card supplied by the new provider. If not, leave as is. If empty, add a SIM card from the network provider that you want the phone to work with, also supplied by that provider.
3. Restart the phone. The phone will detect the new SIM card and will ask for the IMEI code as confirmation to move forward. Entering the code at this point is what allows the unlocked phone to be programmed, the inserted SIM card is what makes the unlocked phone programmable. After entering the code the phone will be programmed and begin functioning with the new network.
