The SIM-free iPhone comes without a wireless contract commitment or carrier financing. It doesn’t come with a nano-SIM card for iPhone 6s, iPhone 6s Plus, iPhone 6, iPhone 6 Plus, or iPhone 5s. And because it’s unlocked, it isn’t tied to one carrier, so you can get a nano-SIM from any supported carrier worldwide, such as AT&T, T-Mobile, Verizon, or Sprint in the United States.
Purchasing a SIM-free iPhone means you will not qualify for the lower iPhone price associated with a contract or a carrier installment plan.
If you don’t want a multiyear service contract, or if you prefer to use a local carrier when traveling abroad, the SIM-free iPhone is the best choice.
The SIM-free iPhone 6s model is A1633 and the SIM-free iPhone 6s Plus model is A1634.
The SIM-free iPhone 6s starts at $649 USD.
