3.6 Installing the SIM card
The Regesta PLC has a Wireless WAN interface that, in order to operate, may require at least one SIM card to be in-
serted into the device. Some carriers in certain countries provide services (CDMA) that do not require SIM cards.
The Regesta PLC has two SIM trays. Both trays are located under the device's protective case and are labeled SIM1
and SIM2.
In installations where only one SIM card is required, we recommend installing it in the main SIM1 tray.
Warning
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 connectors protective casing to access the trays.
When inserting the SIM cards, please protect yourself against electrostatic discharges (ESD).
Do not touch the SIM card connectors.
To access the SIM trays, you need to remove the protective case. Please refer to
Removing/Installing the connector
on page 10 to learn how to remove the casing.
3.6.1 Identifying the SIM trays
Once you have removed the case, you will be able to see the different components illustrated below.
The Regesta PLC incorporates 2 SIM cards, which allow you to execute some special configurations. For example,
when installing two SIM cards one can be used as backup. To carry out this type of configuration, you must assign a
tray to each SIM (since they require different configuration parameters).
The SIM trays are identified as SIM1 and SIM2 (i.e., socket 1 and socket 2).
