I have the same problem with a new JY-UOS03N4G.
no SIM card detected.
SIM card working perfect on a smartphone, compatible with this device, even tried with another SIM card with the same issue.
Installed latest firmware : same issue...
The support told me they where trying to solve the problem (looks like it's a software problem ?)
It's a problem to sell non working devices, I guess I won't buy Joying anymore...
