The Nokia 5510 is a type of 2G mobile phone. Aside from its music playing abilities (detailed below), many aspects of the phone are similar or identical to its predecessor, the Nokia 3310. has a 64 megabyte memory for storing .lse audio files. The Nokia 5510 features a full QWERTY keyboard and an 84 x 48 monochrome display. Its successor is the Nokia 3300.
The 5510 shared many of the features of the Nokia 3310, such as a built-in calculator, stopwatch and a reminder function. It also includes the same 5 games that came with the Nokia 3310: Snake II, Space Impact, Bumper, Bantumi, and Pairs II. However, the 5510 also had the ability to play digital music files transferred onto its 64MB internal flash memory via USB (encoded in either MP3 or AAC format); as well as being able to receive FM radio.
The 5510 is unusual compared to most mobile phones, as it has a has an almost complete QWERTY keyboard, rather than the conventional telephone keypad. This keyboard is divided on the left and right sides of the front panel, with the 84 x 48 monochrome display at the center, and the navigational buttons below it (the display and navigational buttons are almost identical to those found on the 3310). Despite (or, perhaps, because of) the full keyboard, the 5510 lacks the predictive text ability that other phones in its family (such as the 3310) had. Also, 4 black buttons are located on the side of the phone to allow quick access to the music player, FM radio, and the volume controls.
The 5510 can play both MP3 and AAC music files once they are converted and transferred by the nokia PC suite, as well as record audio directly from its internal FM radio, or though its built-in 2.5 mm (3/32")audio jack. Any songs recorded by the phone are encoded in the same format used with music transferred to the phone. The music player on the phone also has a built-in equalizer with several pre-sets to fine-tune the music being played.
The Nokia Audio Manager software downloads music from the computer to the phone. There are also some alternative software that allows users to transfer music, such as Nokia Audio Loader, and Nokryptia for Linux.
The internal part of the 5510 has a cellphone unit inside which resembles that of the Nokia 3310.
The removable backplate on the handset was designed in such a way that pressure on the middle of the plastic could easily cause the plate to crack, This was highlighted in many reviews of the model at the time of release.
