Hi Chris,

[quote user="c.booth"]In the meantime, would monitoring notifications from the "AT+CNEC=24" command help us determine the cause of the rejection from the cell tower? The problem affected all devices within a specific location, and all devices are always stationary.[/quote]

Yes. You can monitor rejection causes using AT+CNEC=24.

I am closing this ticket. If you need further assistance, please open a new ticket.

Best regards,
Dejan

Hi Dejan,

Thank you for your response.

Since raising this ticket, we have not experienced the issue. Previously, it was a persistent problem for several months.

Could you please close this ticket for now? If the issue reoccurs, I will create a new ticket with the application logs and any additional information required.

Hi,

Could you provide more information about your application?

Could you provide your application log?

How many devices are affected by this problem? Are all devices affected at the same time? Are devices moving or stationary?

Best regards,
Dejan
