Hello team, I have a problem with my EC25-AU Mini Pcie because when trying it with different hardware/sim it always shows the same message “SIM is not ready”.

log:

This is the test syntax of these two commands. They return lists of the supported values, and not the currently set values.

You need the read syntax. That’s with a trailing ? and not =?

AT+QSIMDET?
AT+QSIMSTAT?

Hi Snowgum, the response after execution :

[2023-07-02 20:46:35:460_R:] +QSIMDET: 1,0

[2023-07-02 20:46:35:460_R:] OK
[2023-07-02 20:47:06:698_S:] AT+QSIMSTAT?
[2023-07-02 20:47:06:754_R:] AT+QSIMSTAT?

These are not the default settings, as detailed in the EC2x&EC9x&EG2x-G&EM05 Series AT Commands Manual.

Default values are the underlined ones in AT command manuals.

Have you tried running with the default settings? That’s:

AT+QSIMDET=0,0
AT+QSIMSTAT=0
