The Ericsson GA318 was an evolution of the highly successful
Ericsson GH337 with a twist. It was redesigned to be a more consumer-friendly and more affordable device with a coloured facsia and smoother edges. The ear-piece design was also simplified.
The GA318 was an all plastic device compared to the GH337 which had a metal mid-frame. It was offered in blue, green and grey. The unit in the Mobile Phone Museum collection is the grey variant.
