Updating VuLink
Understanding VuLink SIM Cards
The automatic update option ensures that VuLink always has the current firmware.
External SIM Card
Built-in SIM
VuLink attempts to use an external SIM card for all communications if one is present. If
communication via the external SIM fails, VuLink uses the built-in SIM instead.
If an external SIM card isn’t present, VuLink uses its built-in SIM for all communication.
