The 5510 shared many of the features of the Nokia 3310 due to both phones sharing components with each other, such as a built-in calculator, stopwatch and a reminder function. It also includes the same five games that came with the Nokia 3330: Snake II, Space Impact, Bumper, Bantumi, and Pairs II. However, the 5510 also had the ability to play digital music files transferred onto its 64 MB internal flash memory via USB encoded in LSE format via the included Nokia software (from either MP3 or WAV format); as well as being able to receive FM radio.
