Excerpt: Three has updated the modem it uses for its Mobile Wi-Fi (or Mi-Fi as some people call it) service to the Huawei E585 model, the older one being the 3 Mi-Fi Mobile Wi-Fi (Huawei E5830) . Confused? You shouldn't be, but is it just a number change or is there a reason to ask for an upgrade?
Pros: Connect up to 5 devices wirelessly, improved status screen, 3 home hub to help monitor data
Cons: Can't easily see continuous data usage, requires good 3 network coverage to work
