We will be showing off the SIM Bank at the EU Summit in May.
However, the SIM bank has 8 SIM slots which can be used to provide remote SIMS to other Pepwave devices (like the SpeedFusion Engine / HD2 Mini, shortly). The SIM bank can be connected to the device via Ethernet cable - providing easy access for changing SIMS. However, the SIMS can also be provided remotely, via SpeedFusion or from a Public IP address.
Imagine a fleet of boats cruising around Europe at the moment, each boat would need to have at least one SIM for each Country it would be visiting (to keep costs down). With the Remote SIM Bank (in a central location), you could have 8 SIMS installed, one per Country perhaps, then as a boat passes between Countries the SIM Bank would provision a different SIM for the device to use, based on Geographical location.
Each SIM in the SIM Bank can be assigned to multiple devices, but each SIM can only be used by one device at a time, Therefore, the fleet of boats in the above example could all have access to all 8 SIMS in the SIM Bank, but only one boat could use the Ukraine SIM at a time.
Hope this helps,
