2.2 Installing the SIM card
The Teldat H2 RAIL Lite has one or two Wireless WAN interfaces. For them to operate, you may have to insert at
least one SIM card in the device.
There are certain services (CDMA) provided by several carriers in some countries that do not require SIM cards. In
installations where a SIM card is required, you must always insert at least one.
The Teldat H2 RAIL Lite has two SIM trays. Both are located inside the device.
In cases where it incorporates two modules, a SIM tray is automatically assigned to each module.
When only one SIM card is going to be used, it can be inserted into either of the two SIM trays. However, you must
remember to configure the router correctly so it selects the appropriate tray.
Having 2 SIM trays allows you to carry out some special configurations. One example is installing two SIMs and us-
ing one as a backup to the other. To carry out this type of configuration, you must set the tray that has to be associ-
ated to each SIM (since each SIM requires different configuration parameters).
Warning
This device is compatible with 1.8V and 3V SIMs. Do not install SIMs that do not support these
voltages.
Never install the SIM cards when the device is switched on.
Always disconnect the device from the main power supply before installing the SIM cards.
Always disconnect the device before removing the casing to access the trays.
When inserting the SIM cards, please protect yourself against electrostatic discharges (ESD).
Do not touch the SIM cards connectors.
To access the SIM trays you need to open the upper casing of the device. To do this, you need to undo the two
screws located on the upper part of the front panel, the two located on each of the side panels and the screw on the
upper part of the rear panel.
