Hello, I have 2 nrf9151-dk HW rev. 1.4.0. Both of them don't detect SIM card despite the fact my FW worked completely fine on nrf9151-dk with older HW rev (I believe it was 0.7.0). I've tried quick start guide with firmware for cellular development but this one also doesn't work. I've applied board configuration with sim card chosen as source. Board: nRF9151 DK HW rev 1.4.0 (two units affected) Modem FW: mfw_nrf91x1_2.0.4 %XSIM: 0,9 on both boards SIM confirmed working on other hardware Factory reset attempted — no improvement %CSUS: 0 confirms physical SIM is selected I verified few things: > AT%CSUS? %CSUS: 0 OK > AT%XSIMSELECT? +CME ERROR: 0 > AT%XSIM? %XSIM: 0,9 OK > AT+CGMR mfw_nrf91x1_2.0.4 OK > AT OK > AT+CFUN? +CFUN: 1 OK > AT+CIMI +CME ERROR: 0

nrf9151-dk v.1.4.0 SIM not detected

Hello,

I have 2 nrf9151-dk HW rev. 1.4.0. Both of them don't detect SIM card despite the fact my FW worked completely fine on nrf9151-dk with older HW rev (I believe it was 0.7.0). I've tried quick start guide with firmware for cellular development but this one also doesn't work. I've applied board configuration with sim card chosen as source.

Board: nRF9151 DK HW rev 1.4.0 (two units affected)
Modem FW: mfw_nrf91x1_2.0.4
%XSIM: 0,9 on both boards
SIM confirmed working on other hardware
Factory reset attempted — no improvement
%CSUS: 0 confirms physical SIM is selected

I verified few things:

> AT%CSUS? %CSUS: 0 OK
> AT%XSIMSELECT? +CME ERROR: 0

> AT%XSIM? %XSIM: 0,9 OK

> AT+CGMR mfw_nrf91x1_2.0.4 OK

> AT OK > AT+CFUN? +CFUN: 1 OK

> AT+CIMI +CME ERROR: 0

Hello, and thanks for reporting! I will forward internally to our HW team to verify.

Kind regards,
