The Sony Ericsson Z310i (and its sister product the Sony Ericsson Z310a) had a design that was inspired by the
Sony Ericson Z610. The Z310i was a tri-band GSM phone that was sold around the world, except for the US where the Z310a was offered to provide a quad-band variant.
The phone had a 65k colour display and included a basic VGA (0.3 megapixel) camera and a small 96x64 pixel monochrome display hidden under the semi-transparent surface on the outside face of the phone. It also concealed several indicator lights that could be customized to show a different colour for different callers. It was also possible to upload photos directly to a blog site.
The phone was available in three colours: Jet Set Black, Blush Bronze and Lush Pink colour combinations.
