This command allows the external application to activate/deactivate the ciphering indication. The ciphering indication allows the external application to detect when the mobile connection becomes deciphered and thus unsecured.

Test command gives the current value of the <switch> parameter, informing if the indicator is enabled or disabled.

The ciphering indicator feature may be disabled by the home network operator setting data in the “administrative data” field (EFAD) in the SIM as defined in GSM 11.11.
