The iPhone SE, is indeed the most basic iPhone currently available on the market. It is a 4-inch device, with the exact same specs as the iPhone 5 that came out in 2012. The iPhone SE has a slower processor, comes in 16GB model only and lacks the 3D Touch functionality of the iPhone 6S. The iPhone SE is a great device and I would recommend it to anyone who finds the iPhone 6 or 6S too big or too expensive.
