AT+CPIN?
code
OK
SIM card inquiry
(code = ERROR: no/faulty SIM card
code = +CPIN: SIM PIN: waiting for PIN
code = +CPIN: READY: PIN active)
AT+CPIN="n" OK
Enter PIN, switches modem active.
e.g. AT+CPIN="1234" (if PIN is 1234)
AT+CLCK=
"SC",0,"n"
OK
Disable PIN lock after power off. (n = PIN)
e.g. AT+CLCK="SC",0,"1234"
Attention: First enter PIN using AT+CPIN.
AT+COPS?
+COPS: 0,0,"Bearer"
OK
Inquire bearer service. Will be shown only,
when SIM card is active and antenna con-

(2,"E-Plus",,"26203"),
(3,"Vodafone.de",,"26202"),
(3,"o2 - DE",,"26207"),
(3,"T-Mobile D",,"26201"),,(0-4),(0,2)
List of available bearer services.
AT+CBST=s,
n,e
OK
Choose transmission mode
(speed s=1 for 300 Bit/sec V.21, s=2 for
1200 V.22, s=3 for 1200/75 V.23, s=4 for
2400 V.22bis, s=5 for 2400 V.26ter, s=6 for
4800 V.32, s=7 for 9600 V.32, s=65 for 300
V.110, s=66 for 1200 V.110, s=68 for 2400
V.110, s=70 for 4800 V.110, s=71 for 9600
V.110),
(name n=0 for asynchronous mode),
(element e=0 for transparent oder e=1 for
non transparent transmission)
e.g.. at+cbst=7,0,1 (for 9600 Bit/sec V.32,
asynchronous mode, non transparent)
AT&F
OK
Set all parameters to factory defaults.
Attention: Data rate and data format will
be changed to 19200 Bit/sec, 8, N, 1. Ad-
just parameters of terminal program re-
spectively.
ATS0=n
OK
This parameter setting determines the num-
ber of rings (0 to 255) before automatic an-
swering.
e.g. ATS0=1 (Modem answers after first
ring)
Attention: ATS0=0 disables automatic
answering.
ATS0?
1
OK
Returns the number of rings before auto-
matic answering.
ATE0
OK
This disables the modem to send echoes of
characters received from PC during com-
mand state.
ATQ1
(no answer)
This parameter setting disables transmission
of result codes to the PC. Information text
transmitted in response is not affected by
this setting.
AT&W
(no answer because of ATQ1)
Saves the current parameter setting in the
user-defined profile. This settings are active
after every resumption of power supply.
Attention: At the end of every programming the settings have to be saved permanently using
the AT&W command. This ensures that the parameters are restored after power
failure.
