nrf9160

I purchased a SIM data from ILIAD and I am trying to connect to network, but the AT command AT+CEREG? : +CEREG: 0,4  instead of 0,5 as I expect.

The lte_lc_connect_async hangs forever without errors  ..

What I should check and/or setup to get connected ?

Hello,

What I should check and/or setup to get connected ?

Have you tried running AT%XSIM command to check the SIM status? Have you checked if the SIM card requires additional activation with the provider? Are you using a custom board?

Hi, in the meanwhile I realized that the SIM provider does NOT support LTE-M so I guess the problem is related to that. I already purchased another SIM that officially supports LTE-M. We may leave the ticket in stand-by until I receive and test the new SIM. Do you confirm that nRF9160 DO NOT work with 'normal' LTE ? 

Thanks a lot for your response.

Best regards

Hi, I tried to use the new SIM but the registration to LTE-M do not happen. The command AT%XSIM? %XSIM: 0,1 is ok. I see the message RRC connected and then RCC idle  and the cycle repeats. I Have the trace file but I don't see a way to upload it ..

Thanks

Yes, regular LTE is not supported.

If you have any further problems, please submit this in a separate ticket. It seems to me that the original question has been addressed.
