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.
If this feature is not disabled by the SIM, then whenever a connection is in place, which is or becomes deciphered, an indication is given via the unsolicited result code *ECPV:<ciphering>.
<switch> Description

0Ciphering indication is off. Disable the ciphering indication, *ECPV is not sent
Unsolicited Result Codes:
