 Activation procedure

The activation procedure is outlined in a step by step process in the following sections.
2.1 Retrieve the ICCID
The first step is to identify and enter the ICCID code. The ICCID is available on the top surface of the package. The ICCID can be also retrieved directly from the device where the ST4SIM is used. To retrieve this information, the user must access the modem through a configured terminal on the relevant COM port. The terminal configuration is shown in the figure below.ST life augmented AN5740 Embedded SIM Devices

The ICCID is displayed after entering the AT command at AT%CCID via the terminal console as shown in the figure below.ST life augmented AN5740 Embedded SIM Devices - fig

In the example above, the ICCID is 8944477300000021070
2.2 Connect to the Truphone ® web portal to activate the eSIM profile
The second step is to connect to the Truphone ® web portal.
The user must connect to the Truphone ® web portal https://iot.truphone.com (using Chrome ™ ) and follow the instructions provided to create a user account if needed. Once logged-in, the user activates the ST4SIMs from the dashboard page as shown in the screen below.

The activation of the SIM card may take a few minutes to complete. The SIM card status is shown on the dashboard once it is activated.

2.3 Perform a network search and registration
The third step is to connect and register to a cellular network. To force the device to search and register to a cellular network (also known as PLMN selection), the user simply needs to reboot the device. The first time the board registers on the network may take several minutes to find a network and register. This may take between 15 and 20 minutes. The registration is based on the radio environment, Truphone ® network availability and the technology of the network being used. To speed up the network search, the user may follow the tips that are provided on Truphone ® web portal.
