Talking to our sales team, please reach out to Farnell directly and they should handle the replacement. If you have any issues, please let us know.

We are sorry for the inconvenience.

Kind regards,

So we have 3 DKs in total ordered from Farnell. 1 order was on me, 2nd order with 2 boards on my company. If you'd need more details like order numbers/serial number etc let me know

Hello, sorry for the late reply. We are aware of an issue with the production of the boards. You should get this board replaced. From whom did you order your boards?

Kind regards,

Just wanted to checkout if there is any progress on the issue? That's a big blocker for me which I need to resolve ASAP.

Yes, I flashed AT Commands app from Quick Start guide, the application itself works, but SIM card is not detected.

[quote userid="77062" url="~/f/nordic-q-a/128476/nrf9151-dk-v-1-4-0-sim-not-detected/568015"]Could you please provide a modem trace from both new and old DK with the same SIM card?[/quote]

I attach trace from new DK, the old one suffered HW issues and I cannot operate on it anymore.

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!
