MC7304 AT+CSIM phone failure

IoT Modules MC/EM Series
1

Hi,

I’m trying to open a logical channel via a specific applet on SIM CARD using the AT command +CSIM.
This command is working fine on a MC8090 but on the MC7304 I always get “+CME ERROR: phone failure”
The AT command is sent using the USB interface /dev/ttyUSB2 on linux.

AT+CSIM=42,“00A4040010A0000000186000000000000089999941”
+CME ERROR: phone failure

Following documentation the AT+CSIM command is supported by both modem.

Is there a specific configuration to execute this command on the MC7304?

Thanks
Best regards

CSIM command is supported by MC7304. I have the following responses from my module…

AT+CSIM=14,“00A40004026F7B”
+CSIM: 4,“6A82”

OK
AT+CSIM=34,“00D600000CFFFFFFFFFFFFFFFFFFFFFFFF”
+CSIM: 4,“6986”

OK

but of course, i faced issue for
AT+CSIM=42,“00A4040010A0000000186000000000000089999941”
+CME ERROR: 0

So the problem is with the parameters and not with the CSIM command.
