Can you share AT command sequence for nrf9160? is there any AT command to enable roaming on nrf9160?

I have tested with JIO SIM but nrf9160 is not registering for NB-IoT. I am using a mobile JIO SIM as part of my testing. Do i need to use any Special IOT SIM's for testing? logs are attached.devzone.nordicsemi.com/.../trace_2D00_2024_2D00_07_2D00_18T12_2D00_07_2D00_02.057Z.mtrace devzone.nordicsemi.com/.../trace_2D00_2024_2D00_07_2D00_18T13_2D00_58_2D00_12.493Z.mtrace devzone.nordicsemi.com/.../trace_2D00_2024_2D00_07_2D00_18T14_2D00_03_2D00_11.124Z.mtrace

According to the GSMA Mobile IoT Deployment Map, Jio is the only provider supporting NB-IoT.

Does the Quectel BG96 connect via EGPRS? The nRF91-series are LTE-m and NB-IoT only. Please verify that SIM supports these two.

Hello,

Your device is rejected with cause 19

Cause #19 – ESM failure This EMM cause is sent to the UE when there is a failure in the ESM message contained in the EMM message.

This is referring to this cause

Cause #31 – Request rejected, unspecified This ESM cause is used by the network or by the UE to indicate that the requested service or operation or the request for a resource was rejected due to unspecified reasons.

What kind of SIM is this? Does it support NB-IoT? In what location are you testing? I.e. does the local network provide any answers?

Kind regards,
Øyvind
