MC7304 Insert SIM in Windows 10

normally we cannot read sim card number.
But you might try AT+CNUM

Hi jyijyi
This is now resolved thanks for your help.
I had to manually switch to slot 1, using command AT!UIMS=1.
Is there a command for the SIM slot to be detected automatically?
Thanks

not sure if "SIMHOTSWAPDIS” in AT!CUSTOM works for you.
You can give a try.

Thats ok I’ll set this as a solution now.
