Hyundai appears to be bringing flip phones back to the market. The Hyundai Flip feature phones are a thing of the past now that almost everyone uses either smartphones or just simple keypad phones. But Hyundai took the decision to bring the flip phones back. They will bring the flip phone back based on the FCC filing.
The FCC is the Federal Communications Commission which is an independent US government agency which regulates international communication by means of radio, television, satellite, and cable. The mobile phone with model number D275D is lying with the FCC for certification.
