The $12 “Gongkai” Phone
How cheap can you make a phone?
Recently, I paid $12 at Mingtong Digital Mall for a complete phone, featuring quad-band GSM, Bluetooth, MP3 playback, and an OLED display plus keypad for the UI. Simple, but functional; nothing compared to a smartphone, but useful if you’re going out and worried about getting your primary phone wet or stolen.
Also, it would certainly find an appreciative audience in impoverished and developing nations.
