> 15.3 | Related AT Commands

> The following commands might be of interest while using the RSA feature.

> • | AT^SCKS This AT command is used to check the current status of the SIM (local or remote).

> • | AT^SSET After power on and personalization (PIN entry if required), the ME starts reading data from the SIM. Please keep in mind that after entering the PIN, even after the TE sends "OK", subsequent commands that need access to data stored on the SIM may be blocked for up to 30 seconds. It may take even longer to access the remote SIM depending on the establishment of the RSA communication link. Therefore, it is recommended to take advantage of the "^SSIM READY" URC enabled with the AT^SSET command. This URC notifies the user when the process of reading SIM has completed. Afterwards all commands regarding to SIM data files can be used, e.g. the SMS and phonebook commands.

> • | AT+CLCC This command is recommended for querying the state of current calls. A list of all active calls will be returned. This is especially important when the user wants to terminate the SAP connection using AT^SRSA=<devId>,<sapRole>,,,,<discType>; with <sapRole> set to 0 and <discType> set to 1. All calls or active GPRS contexts established via remote SIM will be terminated and the ME will use the locally attached SIM card.

> • | SIM data storage It is recommended that all user relevant data are stored on the SIM only. For example, added phonebook and SMS entries in the client's storage are not accessible after a RSA connection.
