The unlocked iPhone includes all the features of iPhone but without a wireless contract commitment. You can activate and use the unlocked iPhone on the supported GSM wireless network of your choice, such as AT&T or T-Mobile in the United States. The unlocked iPhone will not work with CDMA-based carriers, including Sprint and Verizon Wireless.
If you don’t want a multiyear service contract, or if you prefer to use a local carrier when traveling abroad, the unlocked iPhone is the best choice. If you choose T-Mobile, your iPhone comes with a T-Mobile SIM card already installed. You will need to contact T-Mobile or visit an Apple Retail Store to activate your iPhone.
Otherwise, the unlocked iPhone does not come with a micro-SIM card for iPhone 4s, or a nano-SIM card for iPhone 5c or iPhone 5s so you’ll need to get one from any supported GSM carrier worldwide. To start using your iPhone, simply insert the SIM card into the slot and turn on iPhone by pressing and holding the On/Off button for a few seconds. Then follow the onscreen instructions to set up your iPhone.
Purchasing an unlocked iPhone means you will not qualify for the lower iPhone price associated with a contract. The unlocked iPhone 5c model is A1532 (GSM). The unlocked iPhone 5s model is A1533 (GSM).
