Hello Nordic Community,
I made custom hardware using nRF9160. I updated modem with latest firmware version 1.1.0.
After updating at_client example code my log file as shown below,
AT+CESQ AT+CEREG? This log include without yellow wire hardware.

AT%XSIM returns 0.
After more debugging of hardware I noted that 1.8v is not coming out from nRF9160 modem's SIM_1V8 pin.
How could I test hardware now? and Why 1.8v is not coming out from pin?
Thanks and regards,
Nikunj
