The Nokia 5110 features an 84×48-pixel monochrome LCD with four LED backlights, operated by the Philips PCD8544 display controller.

The Nokia model 5110 received some notoriety following the triple October 2002 Bali bombings that resulted in 202 deaths.

A shard from the (remote bomb detonation) phone was recovered outside the US consulate in Denpasar.

With this information police & intelligence could then unravel the entire Jemaah Islamiyah terror cell's network.

The 5110i has longer talk and standby times, and had a more ergonomic, redesigned, silicone keypad.
