The Nokia 6310 is a business-oriented mobile phone announced on 15 March 2001^[2] and released at the end of the year as the successor of the Nokia 6210.

This phone was used on the Mercedes-Benz S-Class (W220) (1998—2006 type), where it was held in a cradle and connected to the car's integrated car phone and media system called COMAND APS.^[3] It was also Nokia's first mobile phone with Bluetooth connectivity (version 1.1).

Despite the lack of polyphonic ringtones, it was the first Nokia phone to feature a startup tone in ADPCM format. Polyphonic ringtones were skipped due to the relatively low speaker volume during playback of ADPCM files.^[4]

An updated variant of the 6310 was released in 2021 to celebrate the phone's 20th anniversary, featuring modern-day updates including a 2.8" color display, polyphonic ringtones, a VGA rear camera and a microSD slot.^[5][6]

In April 2024, a refresh of the model was launched.^[7]
