4 Installing the SIM card
Chapter 4 Installing the SIM card
The OA5725A routers have a Wireless WAN interface, which, in order to operate, may require at least one SIM card
to be inserted in the device.
Certain services (CDMA) provided by some carriers in a few countries that do not require SIM cards. In installations
where a SIM card is required, you must always insert at least one SIM card.
The OA5725A has two SIM trays. Both are located inside the device.
The OA5725A can incorporate one or two Wireless WAN modules.
• If the device has two modules, a SIM tray is automatically assigned to each module.
• In devices where there is only one WWAN module installed and only one SIM card is used, the latter can be placed
in either one of the two SIM trays; however please must bear in mind it is essential that the router is configured to
select the appropriate tray
In this case, in addition to having 2 SIM trays, you can carry out some special configurations. One example of this
type of configuration is when you install two SIMs where one acts as backup to the other. In order to execute this
type of configuration, it is essential that you identify the tray to be associated to each SIM (as each SIM requires dif-
ferent configuration parameters).
Warning
This device is compatible with 1.8 V and 3 V SIMs. Do not install SIMs that do not support these
voltages.
Warning
Never install the SIM card when the device is switched on.
Always disconnect the device from the main power supply before inserting the internal SIM.
Always disconnect the device before removing the casing to get to the internal SIM.
When inserting the SIM card, please protect yourself against electrostatic discharges (ESD).
Do not touch the SIM card connectors.
To access the internal SIM, you need to open the upper casing of the device. To do this you need to undo the four
screws: two are located on the upper corners at the front of the device and the other two on the upper corners at the
rear.
