Registration: Unknown while using nRF9160 DK with T-Mobile SIM?

[MAhmed106]

Hi Nordic 

We are evaluating nRF 9160 for our next revision of the PCB, and we are testing nRF9160DK. 

It came with a sim, which i tried to activate by nRF cloud, but it couldnt get activated, then i plugged in T-Mobile sim.

I ran asset tracker project and it started sending temperature and other sensor data to the nrF cloud. 

But after that now kit is not even registering to the network. 

I am very new to this kit and if i doing anything wrong please let me know.

Thanks

Hello, 

If you have an issue with the iBasis SIM, please contact iBasis Tech Support via DevZone or send an email through their customer support. There have been some issues with the iBasis SIM cards.

But after that now kit is not even registering to the network. 

 Please install the nRF Connect for Desktop tool, and the LTE Link Monitor app from inside the tool. Have a look at this introduction video on how to use. From here, please provide the log output from the LTE Link Monitor, which should show why it's not registering to the network. 

Thanks. 

Kind regards,
Øyvind

Problem is fixed when i changed config settings from LTE-M to NB-IOT.

Thanks
