Hello,
It would be helpful, if you could provide a more detailed description of your intended use case.
Teltonika devices are automatically connected to RMS by default, as long as the device has internet access.
If the connection to the network itself is interrupted, there are alternatives, such as failover, SIM switch or automatic reboot options to restart mobile connection, modem or the router.
Connection to RMS issues might also indicate expiration of a credit or running out of RMS data, in which case Auto Reboot would not make any impact.
In some cases, disconnect may be related to the device's time being incorrect.
Lastly, connection issues could be a result of updates, other works on RMS side, where, again, auto reboot would not help to gain anything.
Best regards,
