I have a Huawei E585 Mifi device, which works great for mobile broadband. It was originally on the 3 network but was unlocked, I bought it on trademe.

The device has the capability of sending and receiving text messages. When I go into the web interface it tells me I have 25 messages (all automated notifications), but when I hit the "text messages" link it briefly shows the screen that would let me choose between inbox and creating a new message, but it quickly disappears and goes back to the main menu page.

Does anyone have any idea how I can get into that screen?
