UNIVERSE SCMi250u is the first of its kind to make use of the USB 1.1 (Universal Serial Bus) interface for the computer to connect to the Internet. It takes the DC power directly from the USB interface so there won't be any charging device required. With GPRS class 8 (4 downlinks & one uplink), 64Kbps throughput can be easily achieved. The driver software is available for Windows 98/ME/2000.
