Hello @TheMissingLink,
The HD2 dome can operate in two ways:
- You can install 2 x SIMs for each of the internal modems
- You can use the SIM Injector / FusionSIM with or without internal SIMs
We do not advise opening the MAX HD2 Dome unless it is absolutely necessary, use a SIM Injector in preference on the same physical network as the MAX HD2 Dome…
We deployed the first of these here in Australia, based on our experience we recommend only installing the internal SIMs when you are going to have the SIM Injector/FusionSIM remotely located away on a different physical network. This is the situation when the SIMs will be left in the operations/data centre, your HD2 Dome is going to need an initial connection so to establish the link back into your SIM Injector / FusionSIM.
Happy to Help,
Marcus
