Physically, the Firefly has to be one of the smallest and lightest phones available. Our review unit weighed a mere 58.5g (2.06oz) - including the SIM card. Few devices available anywhere can match that low weight. Physically, the Firefly measures up at 88mm x 44mm x 20mm (3.46" x 1.73" x .79"), making it smaller than a typically sized business card. Making a handset that small is not so much a huge engineering feat when you consider that the Firefly has only 5 buttons and a small display on its front.
