Dear aamirniaz434,
I have tried multiple ways, by enabling and disabling SIM detection using AT+QSIMDET command. Please find the below AT response file for your reference.

Actually, I’m not getting any voltage on SIM signal pins(SIM_VDD, SIM_RST, SIM_CLK, SIM_DATA) in all the pins I’m getting 0V. I don’t know why module is not providing voltage here.
Please let me know where I’m missing, how to get it up this module.
