One of the slimmest-width phones Nokia had made, the Nokia 7210 was also one of the first devices with a color screen. Released in 2002, the daring design of the keypad brought in many customers who wanted to upgrade from the older handsets.
The phone itself wasn't too groundbreaking but featured a fully square 128 x 128 pixel resolution screen. One of the great benefits of the device was its weight; a considerably lighter 83g compared to the common 133g weight of the Nokia 3310 due to its thinner and more efficient battery.
