Apple launched the iPhone 18 Pro Max in September 2026 as its largest and most capable iPhone. The new model keeps the 6.9-inch Super Retina XDR display but features a smaller Dynamic Island, an aluminum unibody design with Ceramic Shield 2 on the front and Ceramic Shield on the back, and a redesigned rear camera system (Fusion main with dynamic aperture, Ultra Wide, and Telephoto with up to 8x optical-quality zoom).
The iPhone 18 Pro Max is available in Black, Silver, Glacier, and Burgundy, with storage options ranging from 256GB to 2TB. Pricing starts from $1,199 in the US.
Like previous generations, Apple produces several regional versions of the iPhone 18 Pro Max. There are 4 model numbers: A3473, A3716, A3717, and A3718. Although they share the same basic design and core hardware, these variants are configured for different markets and can differ in cellular band support (including mmWave availability), SIM configuration, battery capacity (eSIM-only models are larger due to the absence of a physical SIM tray), and (in the US case) the modem.
Knowing the model number is particularly important if you are buying an iPhone from another country or importing one for use in the United States. Here is a breakdown of the four iPhone 18 Pro Max models and their differences.

iPhone 18 Pro Max A3718
| Description | The A3718 is exclusive to mainland China. It features dual physical nano-SIM support (plus eSIM options) and no mmWave. Local restrictions may limit certain features (e.g., some Apple Intelligence or satellite capabilities depending on configuration). Battery is smaller due to the dual physical-SIM support; wireless charging is limited to 15W in this market. It uses Apple’s C2 modem. If you want to use iPhone in China, this is the recommended model because you can’t install an eSIM profile from Chinese carriers with iPhones purchased overseas. |
