Viewsonic ViewPhone 4e
Mobile World Congress 2012 stroke the world with some of the most high-end devices of the time. But those who travel around much should probably keep a closer eye on one of Viewsonic's GSM dual-SIM smartphones, which include the ViewPhone 4e.
The device can operate with two SIM cards simultaneously, making it easy for frequent travelers to stay connected. The specs are definitely not the most impressive, but we can expect the price to be much more enticing.
