I plugged in my SIM card and it worked RIGHT NOW out of the box. Here the fun ended. All attempts to set the firmware to the "correct" setting for your provider gave poor results. Changes broke the connection and were not saved in most cases. I checked for a firmware update but there is none. Failed to set MTU, Failed to set WAN DHCP setting, just stuck on Static, which I'm not. Thank god I was working with an ISP that didn't require APN setting or probably didn't work either. Either way, it's a good idea with terrible firmware. Yeacomm is much better, albeit without Wi-Fi. Another plus if they ever fix the firmware is that it works on 48v POE so it can be stretched to a pretty decent length with extension cords. I think if they fixed the firmware it would be a good device but for me it's trash now.
