To enable auto dialling for data and voice calls after ME's power on it is necessary to disable PIN authorization
with the command
AT+CLCK="SC",0,<password>. To prevent misuse of this unprotected SIM card it is recom-
mended to limit its network facilities. For details refer to the "FD" parameter of
AT+CLCK.
If dialling starts on DTR line activation, possible responses are as though the dial command were entered by a
TE, for instance:
•OK
If successfully connected and voice call
• CONNECT<text>
If successfully connected and non-voice call. <text> is sent out if parameter setting is
ATX>0. TA switches to
data state.
• +CME ERROR: SIM not inserted
SIM card is needed to set up data and voice calls.
• +CME ERROR: SIM PIN required
PIN is required to set up data and voice calls.
• +CME ERROR: not found
Phone book entry is required for data and voice calls, but no telephone number is provided.
• NO DIALTONE
If there is no dialtone and parameter setting
ATX2 or ATX4.
• BUSY
If busy and parameter setting
ATX3 or ATX4.
• NO CARRIER
If a connection cannot be set up or call is finished by other party.

“;“ Performed dial command leads to a voice call.
“!“ Dial command leads to an emergency call, i.e. ATD "112"; is performed. No
SIM card needs to be inserted in this case.
CAUTION!
AT%D1! setting especially in conjunction with AT&W can easily lead to erroneous
emergency call setups.
Notes
• To suppress arbitrary call releases on DTR deactivation setting of AT&D0 is strongly recommended.

AT%D needs to be the last one.
