A phrase used to describe a half-smartphone and half-tablet mobile device (a phone/tablet hybrid). A phablet is a small pocket-sized mobile device that is a bit larger than the size of an average smartphone, with a touch screen ranging in size from 5 inches (e.g. the Sony Xperia Z) to 6.1 inches (e.g. the Huawei Ascend Mate device).
While larger than a smartphone, the phablet is much smaller than most tablets and can be held and used in one hand. Phablets typically use 3G or 4G networks for cellular calls and are Wi-Fi-enabled devices.
