The Huawei E5573s-856 is a compact, battery-powered 4G LTE Cat4 mobile WiFi hotspot (MiFi) from Huawei's popular E5573 series. The "-856" suffix denotes a regional/carrier variant (commonly distributed via China Unicom), and like other E5573s units it pairs LTE connectivity with a removable battery and a small status-LED interface. It delivers peak download speeds of 150 Mbps and shares up to 10 WiFi clients, making it a typical entry-level pocket router. The "dual firmware" reference in the page relates to the unlocking procedure rather than a hardware difference.
