Nokia 1100

The dirt-cheap Nokia 1100 too is among the best-selling mobile phones of all time. Sporting a no-frills design and stellar battery life, the 1100 was launched in 2003 and had a built-in flashlight. It could hold 50 text messages and came with a cool-collection of ringtones.

We can personally attest to its toughness, as this author has seen it fall from a four-storey building and survive to work just fine.
