Marcin Yes, you can
Ah ok, perfect! Are AT commands universal to lock the cell? (like those used for mikrotiks or Quectel modems).
Marcin You can even instal openwrt on your MF286D...
I'm tempted to install it, but I would like to keep the ZTE with nordic for "normal" use, and maybe in particular situations unmount its modem and mount it in a mpcie adapter or a dell laptop, so that I can make the most of it. Although I would like to modify the antennas of the zte and, maybe, make it a 3d printed box to be mounted in a rack or something like that.
