This product has a terrible user interface and very old firmware. After updating the firmware I still couldn't get the device to work. Don't expect support, the wiki support page links to a post where a determined user claims to have gotten the device to work without AT commands. Since it's supposed to work as a USB stick, I connected the modem to my Windows machine and was able to install the drivers, but I couldn't turn the device on. Waveshare offers a little support.
