Huawei E586 will be able to support download speed at 21.1Mbps and Upload speed at 5.76 Mbps (HSUPA). Beyond the blistering fast speeds, the Huawei E586 MiFi has a horde of other features. Firstly, there’s an OLED display on the front of the unit which displays key information like the amount of data used, speed of the current connection, length of browsing time and dashboard for viewing SMS and changing settings. Compared to other MiFi units, the display alone is enough to win our hearts.
