About model A1660

The model number A1660 belongs to the iPhone 7 (Global) (device identifier iPhone9,1). Apple assigns multiple model numbers to each device for regional and connectivity variants, so one device usually carries several of them.

How do I find the model number on my device?

Open Settings > General > About and read the Model Number field. The number is also printed in the fine print on the back of the device and, on some models, on the SIM tray. Our model identification guide walks through every method.

What is the difference between A1779, A1780 and A1660?

Nothing software-related. These model numbers all refer to the same iPhone 7 (Global); Apple uses them for regional and connectivity variants, and firmware support is identical across all of them.
