Hi charlie,

You suggested very good option to get fast connection to LTE.

I always connected through band 12 for AT&T network. So I just need to use band 12. for that i am using below command.

AT%XBANDLOCK=2,"100000000000"

Except this do i need to use anything else in project and config file

Thank you
Rahul

Hi Rahul,

I also I have other suggestion that may help to find the issue:

1. Use nRF9160: AT Host to test the connection time, so you can confirm that the issue is not related to your custom program.

2. If the problem is caused by LTE network, use Trace Collector to a modem trace for the nRF9160 and send it to us to find the cause.

3. Try to test in different places, just in case your location is on the edge of LTE-M base station coverage.

4. Ask your SIM card provider for more advice.

Best regards,

Charlie
