14.3.1 Reference Process

Command
AT+CUSATE="D30782020181900156"
+CUSATE: "",0
OK
Notes:
Issue 02 (2013-09-18)
 This command is not specified in the standard interface protocol but is introduced to
prevent the main menu information from being lost because SET UP MENU is sent too
quickly.
 If the SIM card does not deliver SET UP MENU, then ^CUSATM: "" will be returned after
the main menu is queried.
<envelope_command> and <envelope_response> consist of the full BER-TLV data

object as defined in 3GPP TS 31.111.
 <envelope_response> is the SIM card's response to the envelope command. It may be
empty.
 <busy> indicates the SIM card status. If <busy> is 0, the SIM card is normal and the
envelope command has been processed. If <busy> is 1, the SIM card is busy. The
envelope command can be resent when the SIM card is idle. If <busy> is 2, the SIM card
is faulty. Check the SIM card and do not resend the envelope command until the SIM card
has been fixed.
