The iPad mini 4 models -- casually described by Apple as a little iPad Air 2 -- pack similar, but not identical, internals in a smaller case.

Both iPad mini 4 models, this Cellular-equipped model and its Wifi only brother, feature a 7.9" 2048x1536 (326 ppi) LED-backlit IPS touch-sensitive display with an antireflective coating, a dual core 1.5 GHz Apple A8 processor, 2 GB of RAM, and 16 GB, 32 GB, 64 GB, or 128 GB of flash memory storage.

Other notable features include dual cameras -- a rear-mounted 8 megapixel "iSight" camera capable of shooting stills and 1080p video and a front-mounted 1.2 megapixel "FaceTime HD" camera capable of shooting stills and 720p video, dual-band 802.11a/b/g/n/ac Wi-Fi with HT80 with MIMO capability and Bluetooth 4.2, as well as dual microphones and speakers. Connectivity to computers, if desired, and power is provided by the Lightning port. Housing color options consist of silver with a white front, gold with a white front and a medium-toned "space" gray with a black front.

The battery life of this iPad mini 4 model is reportedly 10 hours "surfing the web on Wi-Fi, watching video, or listening to music" or nine hours surfing the web using cellular data capabilities.

This Wi-Fi/Cellular iPad mini 4 (A1550) has support for A-GPS, GSM/EDGE, UMTS/HSPA+/DC-HSDPA, CDMA EV-DO, and perhaps most importantly LTE bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 18, 19, 20, 25, 26, 28, 29, 38, 39, 40, and 41. In the US, this single device is designed to run on the AT&T, Sprint, T-Mobile, and Verizon networks and even ships with an "Apple SIM" that is designed to allow one to switch between AT&T, Sprint, and T-Mobile at will (but AT&T  locks the Apple SIM upon activation with the carrier, defeating its purpose entirely, and Verizon does not participate in the Apple SIM altogether). In the UK, Apple also provides an Apple SIM. In other countries, a traditional carrier nano SIM can be used.
