Hi,

I asked internally, and as of now, there's no LTE-M support in India. However, there's support for NB-IoT in some places with the operator Reliance Jio, so you should contact them about whether there's NB-IoT coverage in your area, as well as to get a SIM card with support for NB-IoT.

By default, the modem starts in LTE-M mode in our examples, so if you're going to use NB-IoT you'll have to change that. If your sample or application uses the LTE Link Control driver, which the Asset Tracker application does, you can select NB-IoT with CONFIG_LTE_NETWORK_MODE_NBIOT.

You can also ask our regional sales manager in India, Mr. Gaurav Kapoor, about support for LTE-M and/or NB-IoT coverage in India, as he has more information about the local support for this. If you need his contact information, please let me know so I can make this ticket private and share it with you.

Best regards,

Marte

Thanks for the input. Looks like the issue is in the SIM card. I was trying to test the SiM by inserting it in android mobile and I am not able to access the Internet. How to resolve this issue? I am in touch with my local service provider to check the SIM

Hi,

I assume the project on your nRF9160 DK is the Asset Tracker application. If so, LED 3 blinking indicates that the device is connecting to the LTE network. When LED 3 stays on, the connection is established. You can see what the different LEDs indicate in the Asset Tracker application here.

You can also check LTE connection using the LTE Link Monitor in nRF Connect for Desktop, by looking at the LTE tab on the right. If it's green, then the device is connected to the LTE Network. You can also see which Network you're connected to further down.

Best regards,

Marte
