https://devzone.nordicsemi.com/f/nordic-q-a/84924/nrf9160-couldn-t-connect-over-nb-iot-lteHi community I&#39;m trying to test the functionality of NB-IOT using nRF9160 board. I&#39;m not using the default iBasis SIM card (it doesn&#39;t have the couverage in Tunisia), I&#39;m using orange SIM. In LTE link Monitor, the Modem is power off (red color) anden-USTelligent Community 13Fri, 18 Feb 2022 19:23:29 GMThttps://devzone.nordicsemi.com/thread/353945?ContentTypeID=1Fri, 18 Feb 2022 19:23:29 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f95a8ee4-4249-47fb-abbe-6d1b333a8529&#216;yvind<p>Hello,&nbsp;</p> <p>Sorry to hear that you are facing these issues with your board. First of all, does the Orange SIM support NB-IoT or LTE-m? Please verify this with the service provider. According to GSMA&nbsp;Mobile IoT Deployment Map, there is no coverage for LTE-M or NB-IoT.&nbsp;</p> <p>Next I recommend testing with a more simple/complete&nbsp;application from our <a href="https://www.nordicsemi.com/Products/Development-hardware/nRF9160-DK/Download?lang=en#infotabs">precompiled package found under the download section of Nordicsemi.com/nrf9160dk</a>.
