About model A1550
The model number A1550 belongs to the iPad mini 4 (Cellular) (device identifier iPad5,2). 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.
