You can order an iPhone 15 directly from Apple, which is an excellent option if you don’t want a carrier lock. 

The iPhone 15 and iPhone 15 Plus are thinner than their legacy counterparts. They come equipped with a USB-C port, 6.1-inch and 6.7-inch displays, and the Dynamic Island camera design. The Apple iPhone 15 Pro and iPhone 15 Pro Max come with Apple’s new A17 Pro CPU, a faster neural engine, and camera improvements, including a 5X telephoto lens on the Pro Max. 

You can receive up to $630 in credit when you trade in an older device and purchase through Apple. Apple Card cashback is also available. If your device doesn’t meet trade-in standards, Apple will do the legwork to ensure you can recycle your device for free.
