RE: nrf9151-dk v.1.4.0 SIM not detected

Hello, while investigating the issue we just need to ask some questions in regards to if this is just the SIM interface or the whole board.

[quote user=""]I've tried quick start guide with firmware for cellular development but this one also doesn't work[/quote]

Could you please elaborate more on what this means? From the information provided it seems that you have programmed the Serial LTE Modem (AT Commands)? Does this application run as expected?

[quote user=""]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)[/quote]

Could you please provide a modem trace from both new and old DK with the same SIM card? Capturing a modem trace in Cellular Monitor

Thank you!

Kind regards,
Øyvind
