TRB500 Modem fails?

Teltonika Networks

I have a TRB500 setup with a test simcard. Now i’m trying to install it into a production environment but with the eventual simcard installed the device keeps rebooting (which makes it super annoying to debug).

Before it reboots, I can extract the following log lines, what is happening here?

Fixed with the firmware update found in TRB500 modem update proceedure

Would have been a real timesaver if this update was on the firmware download page.
