I see no received SMS in the logs. Could you try a different SIM, to check if the device receives SMS?
Did SMS reception stop immediately after installing RUT9_R_00.7.00 firmware or after some time using it?
Have you tried legacy firmware afterwards, or the last time the device was able to receive SMS was a year ago?
The troubleshoot file has numerous blocked IPs, which attempted to login to your router via SSH 22 port, from all over the world.
I would like you to try the following:
Flash firmware via bootloader menu to latest Legacy, which you can download here. This should completely clear your device. For instructions refer here. Check if you can receive SMS afterwards. Next, upload the Latest RutOS and also check, if SMS are received.
Next, before enabling HTTP(S) or SSH WAN, replace standard ports to random values above 1024 in Services -> Administration -> Access control and configure a strong and long (no less than 12 characters) password. If remote access is mandatory for a long period of time, consider using VPN or Teltonika's cloud platform RMS.
