On the first step, the customer application informs the FLYFOT product which facilities are supported.
This operation is performed with the +STSF (SIM ToolKit Set Facilities) command, which also allows
activating or deactivating the SIM Toolkit functionality.
On the second step, an unsolicited result +STIN (SIM ToolKit indication) is sent by the product, indicating
to the customer application which command type the SIM Application Toolkit is running on the SIM card.
The last SIM Toolkit indication can be requested by the +STIN? command.
On the third step, the customer application uses the +STGI (SIM ToolKit Get Information) command to get
all the information about the SIM ToolKit command, returned by a +STIN message.
On the fourth step, the customer application uses the +STGR (SIM Toolkit Give Response)to send its
response (if any) to the SIM ToolKit Application.
The +STCR (SIM Toolkit Control response) indication is an unsolicited result sent by the SIM when Call
control functionality is activated and before the customer application has performed any outgoing call,
SMS, SS, or USSD.
