Hi…

It the device lost the connection to internet when SMS goes wrong?

Using auto reboot setting… you cando a auto reboot of the device…

Hello,

I would like to clarify that the router “hangs” for only a few minutes during this process, as it is waiting for a response from the modem. Once the modem responds that the message failed to send, the router resumes normal operation.

This behavior is expected, as the router must wait for the modem’s response.

Additionally, a suggestion has been made to our developers for the modem to respond with a message indicating that it is busy at that moment. Unfortunately, I do not have any information regarding its implementation at this time.

Thank you for your understanding and patience.

Best regards,
