Getting SiteManager online using 3G/4G

First of all, you need to configure SiteManager either by USB, DEV port or via the Appliance Launcher.

A Reboot is needed after inserting the SIM card either directly in the internal slot or in a USB modem. Same for switching SIM cards.

If successful SiteManager will automatically find the APN.

It is also possible to manually lock SiteManager to a specific APN by typing it in.

In the SiteManager GUI under "Setup", you can see what kind of Signal strength (SQ) it acquired.

And the same info from the GateManager/LinkManager interface.
