Chapter 4 Installing the SIM card
The OA5725R routers have Wireless WAN interfaces that may require at least one SIM card to be inserted in order
to operate. There are certain services (CDMA) provided by several carriers in some countries that do not require SIM
cards.
The OA5725R routers have two SIM trays. Both trays are located inside the device casing and are labeled SK1 and
SK2.
In installations where only one SIM card is required, this must be installed in the main SK1 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 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 tray, you need to open the upper casing of the device. To do this you need to undo the four
screws located on the upper side of the device.

4.1 Identifying the SIM trays
Once you have removed the upper casing, you will be able to see the different elements illustrated below.
The OA5725R incorporates 2 SIM cards, which allow you to execute some special configurations. One example is
installing two SIMs and using one as backup to the other. 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 SK1 and SK2 i.e. socket 1 and socket 2.
