I have brought 2 set of Mavic 3 with DJI Cellular 4G dongle and with the hanger for the Mavic 3. I saw the video from China and some video from Hong Kong , that its work very well in China and hong kong , but i don't know why suddenly hong kong doesn't work . My 2 sets of DJI Cellular 4G dongle  became rubbish.

Yeah, Dji BS all of us about the Mavic 3 having 4G, what a disappointment.
