The JioPhone may be smart, but, it’s still a good old feature phone on the inside and out which means that it’s as basic as they come. Basic not so much in terms of features and functionality, but, in terms of design and build, and ease of use. It’s like any other regular feature phone out there, the JioPhone. It’s built entirely out of plastic. The front is dominated by a 2.4-inch screen and a T9 keypad, while the back panel is removable, and so is the battery.
