BT has great ideas but seemingly don’t do their market research before launching some of them. And when they do have a disaster they appear to try very hard to have another one.
In 1999 BT’s Onephone launched, based on an Ericsson GSM/DECT design, providing one phone for home and away. It failed disastrously leaving some distributors with unsalable bricks.
Having woefully overestimated the market once, BT gave the concept another shot with Bluephone / Fusion based on UMA technology.
Although more popular, BT are closing the service so expect loads of new Nokia, Motorola and Samsung handsets going cheap on eBay.
