The GlobeSurfer X.1 is a compact router allowing users with a USB Cellular Modem to easily and reliably connect to the internet. The X.1 does not require any installation software as its built-in GUI (Graphical User Interface) enables users to access its features by simply opening an internet browser (such as Internet Explorer, Firefox, etc.). When a USB Cellular Modem is inserted into the GlobeSurfer X.1, it will establish a LAN (Local Area Network) and allow computers supporting Wi-Fi to access its networking features. Computers without Wi-Fi can also connect via the Ethernet ports on the back of the X.1.Option: ICON 210, ICON 225, ICON 315, ICON 322 (AT& T Quicksilver) , ICON 401, ICON 431 (Vodafone K3760) , ICON 451, ICON 452, ICON 505, ICON 505M, ICON 515M (Orange).
