Chapter 1 - Introduction
CHAPTER 1 - INTRODUCTION
The AT command set is one of the main interfaces for the modem to interact with an external application
layer. CDMA AT commands are defined in TIA/EIA/IS707.3. However, as the wireless applications increase,
TIA/EIA/IS707.3 is not sufficient. In addition, a lot of GSM applications already exist and GSM customers
would like to maintain the same interface in order to make no or minimum changes to the applications to be
used with CDMA modem. To meet the all these needs, CDMA AT command set is designed to cover:
1) IS707.3 AT commands;
2) GSM 07.07 when applicable;
3) GSM 07.05 when applicable,
4) ITU-T v25 when applicable;
5) Proprietary AT set;
6) Customer specific AT commands;
7) Qualcomm defined AT commands.
Please note that in several instances, the GSM 7.07 and 7.05 specifications could not be followed because
of fundamental differences between CDMA and GSM call processing behaviors. In these cases, minimal
changes were made to the GSM-related commands.
Scope of This Document
This document describes the CDMA AT command, its syntax, its responses, and result codes. It serves as

General Indicator +WIND
Description: This is a general mechanism to send unsolicited non-standardized indications to the
application. The identified unsolicited non-standardized indications are:
• Indication during mobile originated call setup that the calling party is ringing.
• Indication of the availability of the product to receive AT commands after boot.
The +WIND is overloaded with two functionalities:
1) posts non-standardized indications and
2) allows the user to specify indication level. For each of these indications, a “bit flow” has
to be indicated.
Values: <IndLevel>
1 (bit-0): R-UIM Presence
2 (bit-1): Reserved
4 (bit-2): Reserved
8 (bit-3): Indication that the product is ready to process all AT commands
16 (bit-4): Reserved
32 (bit-5): Reserved
64 (bit-6): Network service available indication
128 (bit-7): Network lost indication
256 (bit-8): Reserved
512 (bit-9): Reserved
1024 (bit-10): Corrupted RF calibration values (checksum mismatch)
Note 1: If <IndLevel> is equal to 0, no unsolicited “+WIND: <IndNb>” will occur.
Note 2: If <IndLevel> bit 10 is set, the modem will transition to OFFLINE mode.
A combination (addition of the values) is used to allow more than one indication flow. 0 <
d Level ¡Ü 2047 For example: 128 (network lost indication) + 64 (network service available
indication) = 192.
The response is OK if the values are in the previous range.
The unsolicited response will then be: +WIND : <event>
Example Result
+WIND:8
Note: General indication that AT commands are ready to be accepted
The supported events are:

Dial Command D
Description: The ATD command is used to originate a voice, data or fax call. The dial command also
controls supplementary services.
For a data or a fax call, the application sends the following ASCII string to the product:
ATD<nb> where <nb> is the destination phone number.
Note: ATD<nb> is followed by PPP negotiation.
For a voice call, the application sends the following ASCII string to the product:
ATD<nb>; where <nb> is the dialing string or destination phone number, followed a
semicolon “;”. The dialing string may only contain characters “0-9”,”#”,”*” only. Note that
some countries may have specific numbering rules for their CDMA handset numbering.
The response to the ATD command is one of the following:

Mode Preference +COPS
Description: The Mode Preference of a CDMA modem governs the basic system acquisition behavior of
the MS in conjunction with the PRL (Preferring Roaming List). It’s important to note that the
PRL takes precedence over mode preference when guiding the phone to a band or system.
The PRL must allow a particular band first, before the mode preference can take effect. In
other words, a mode preference change is simply a request; the PRL decides whether or not
to allow it. After execution of the +COPS command, an unsolicited +COPS: <mode> will
follow soon to confirm the new mode selection, but not in all cases. See Unsolicited Result
Codes in Chapter 3. All changes to +COPS are automatically saved in NV RAM.
Note 1: AMPS selection is available only in modems that support AMPS mode.
Note 2: Refer to Chapter 20 for AT commands that are applicable to AMPS operation.
Note 3: This command is not available in Sprint®. and Verizon. software versions.
Note 4: CDMA Only (<mode> 1) is the only available mode in RUIM software versions. An
attempt to select any other mode in RUIM software versions will result in an error return.
Values: The parameter values are the following ones:
<mode>
0: Automatic.
1: CDMA Only.
2: CDMA or AMPS only.
3: Analog only.
<term>
0: Permanent – this mode persists until another +COPS command is issued
1: Power cycle – this mode persists until power cycle is performed
Note:

Band Preference +WBND
Description: The Band Preference of a CDMA modem governs the basic system acquisition behavior of
the MS in conjunction with the mode preference (+COPS) and the PRL (Preferring Roaming
List). It’s important to note that the PRL takes precedence over band preference when
guiding the phone to a band. The PRL must allow a particular band first, before the band
preference can take effect. In other words, a band preference change is simply a request;
the PRL decides whether or not to allow it. If the setting is accepted by the MS, the value will
be written to non-volatile RAM and persist after a power-cycle.
Note 1: This command is not available in Sprint®. and Verizon. software versions.

Roam Preference +WRMP
Description: The Roam Preference of a CDMA modem informs the MS whether it is allowed to roam on
foreign CDMA networks or only allow operation on home networks. The determination of
what is a foreign or home network is programmed into the PRL (Preferring Roaming List).
This command simply enables or disables the capability of the MS to roam, based on the
PRL configuration. If the setting is accepted by the MS, the value will be written to nonvolatile RAM and persist after a power-cycle. After execution of the +WRMP command, the
MS may change roaming states. The unsolicited result +WROM: <mode> will indicate the
new state. See Unsolicited Result Codes in Chapter 3.
Note: This command is not available in Sprint®. and Verizon. software versions.
Values: The parameter values are the following ones:

CHAPTER 7 - SIM CARD OPERATIONAL COMMANDS
This section details the commands that are available when a SIM card is present. These commands are
available only in RUIM software versions.
Note that the PIN codes used in this section are for example purposes only and do not reflect the actual PIN
codes programmed into the modem. Contact your service provider to obtain the actual PIN codes used by
your modem.
Enter PIN +CPIN
Description: This command is used to enter the ME (Mobile Equipment) passwords (CHV1 / CHV2 /
PUK1 / PUK2, etc.), that are required before any ME functionality can be used. CHV1/CHV2
must be 4 to 8 digits long, PUK1/PUK2 must be 8 digits long. The application is responsible
for checking the PIN after each reset or power on if the PIN was enabled.
Syntax: Command syntax: AT+CPIN=<pin>
Command Possible Responses
AT+CPIN=1234 OK
Note: PIN code is correct
After 3 unsuccessful attempts to enter the PIN (Personal Identification Number), the PUK
(Personal Unblocking Key) will be required. PUK validation forces the user to enter a new
PIN code as a second parameter and this will be the new PIN code if PUK validation
succeeds. CHV1 is then enabled if PUK1 is correct. The application therefore uses this
command:
Command syntax: AT+CPIN=<Puk>,<NewPin>
Command Possible Responses
AT+CPIN=00000000,1234
Note: Enter PUK and new PIN
AT+CPIN=12345678,1234
Note: Enter PUK and new PIN, 2nd attempt
To ascertain which code must be entered (or not), the following query command can be
used: AT+CPIN?
The possible responses are:
+CPIN: READY ME is not pending for any password
+CPIN: UIM PIN CHV1 is required
+CPIN: UIM PUK PUK1 is required
+CPIN: UIM PIN2 CHV2 is required
+CPIN: UIM PUK2 PUK2 is required
+CPIN: PH-UIM PIN UIM lock (phone-to-UIM) is required
+CPIN: PH-NET PIN Network personalization is required
+CME ERROR: <err> SIM failure (13) absent (10) etc.
Note: that in this case the mobile equipment does not end its response with the OK string.
The response ‘+CME ERROR: 13’ (SIM failure) is returned after 10 unsuccessful PUK
attempts. The SIM card is then out of order and must be replaced by a new one.
+CME ERROR: 16
Note: Incorrect PUK
OK
Note: PUK correct, new PIN stored
Multi-Tech Systems, Inc. CDMA Wireless AT Commands - PN S000294C 51
Chapter 7 - SIM Card Operational Commands
Enter PIN2 +CPIN2
Description: This command is used to validate the PIN2 code (CHV2), or to validate the PUK2 code
(UNBLOCK CHV2) and to define a new PIN2 code. Of course, the +CPIN command allows
PIN2 or PUK2 codes to be validated, but only when the last command executed resulted in
PIN2 authentication failure. PIN2 length is between 4 and 8 digits. The PUK2 length must be
Syntax: Command syntax: AT+CPIN2=<pin2>
Command syntax: AT+CPIN2=<puk2>,<NewPin2>
8 digits.
Command Possible Responses
AT+CPIN2=1234 OK
Note: PIN2 code is correct
After 3 unsuccessful attempts, PUK2 will then be required. PUK2 validation forces the user
to enter a new PIN2 code as a second parameter and this will be the new PIN2 code if
PUK1 validation succeeds. The application therefore uses this command:
Command Possible Responses
AT+CPIN2=00000000,1234

Message Overwriting +WMGO
Description: The +CMGW command writes an SMS to the first location available. To write an SMS to a
specified location, the +WMGO command forces the product to write an SMS (with the
+CMGW command) to the location specified with +WMGO, but for just one +CMGW
command.
Values: <loc>: Location number of the record to write or overwrite

Note: Invalid index (out of range)
On the next AT+CMGW command, the record number used will be the one specified by the
AT+WMGO command. The location is forgotten and, in order to perform a second overwrite,
+WMGO has to be used again.
If the external application specifies a free location, and if an incoming message is received
before the AT+CMGW command, the product may store the incoming message at a location
available. This could be the one specified by +WMGO (the product does not prevent from
this). If the user then issues an AT+CMGW command without changing the AT+WMGO
location, the new message will be overwritten!
Note: that this location number is not kept over a software reset.

CHAPTER 9 - SUPPLEMENTARY SERVICES COMMANDS
Supplementary Service commands are specialized call processing commands used to control carrier
features on the modem such as caller ID, call forwarding, call waiting, 3-way calls, and specialized CDMA
test calls.
Call Forwarding +CCFC
Description: This command allows control of the call forwarding supplementary service, if supported by
the carrier. All calls will be forwarded unconditionally to the phone number specified. The
modem will make a brief call to the CDMA network using an ATD specified prefix number
(country and carrier specific) to setup or cancel call forwarding. An audio tone will be
Values: <number>: The phone number to forward all calls to.
Syntax: Command syntax: AT+CCFC= <number>
produced in the audio path to confirm the change of the call forwarding state.
Note 1: Country and carrier specific call forwarding services (e.g. *68, *72, etc.) may also be
available to the host application in addition to the modem provided +CCFC functionality. The
host application can utilize these enhanced services for call forwarding with the modem ATD
command (e.g. ATD*72).
Note 2: If the “FD” facility is enabled, only the entries in the FDN phonebook can be
forwarded.
Command Possible Responses
ATD*72
Note: Specify the call forwarding
prefix number.

Chapter 9 – Supplementary Service Commands
Calling Line Identification Restriction +CLIR
Description: This command allows control of the outgoing caller ID restriction supplementary service.
Values: <mode>: sets the caller ID restriction for outgoing calls
0: Outgoing Caller ID works normally, according to the subscription of the Caller ID
service.
1: Outgoing Caller ID is restricted. The called party will see ‘Restricted’ on their Caller ID
display.
Note that this command works by automatically pre-pending a *67 to the outgoing dialing
string. Thus, this command will only work on CDMA networks that recognize a *67 to
suppress outgoing caller ID. Also, the original dialing string cannot be longer than 29
characters in length.
Syntax: Command syntax: AT+CLIR=<mode>
Command Possible Responses
AT+CLIR=1
Note: Restrict outgoing caller ID.

Chapter 9 – Supplementary Service Commands
Send Flash to Base Station +WFSH
Description: This command sends a flash or flash with information to the base station. The flash
command is used to manage call waiting and 3-way calls. For call waiting situations when
the 3 party call is received, send a flash (AT+WFSH) to toggle between the two different call
parties. The +WFSH unsolicited AT command will be returned if a flash was sent to the base
station over the air. Note that on CDMA networks, this does not guarantee that an actual
switch between calls took place, because there is no acknowledgement to the modem. For
3-way calls, initiate the first call to party # 1 (see ATD). Then send a flash with information
(AT+WFSH=18005551212) to initiate a call to party # 2, party # 1 will automatically be
placed on hold. The “information” is the phone number of party # 2. Once a conversation
with party # 2 is established, send a regular flash (AT+WFSH) to connect all 3 parties. Send
another flash (AT+WFSH) to disconnect party # 2, or End call (see ATH) to end the call with
all parties. rd

CHAPTER 10 - DATA COMMANDS
Using AT Commands During a Data Connection
To use AT Commands during a data connection (e.g. while the product is in online mode), it is necessary
either to switch to offline mode, or to use the +WMUX command to enable Commands / Data multiplexing.
Note: currently the +WMUX command is not supported yet.
Switch From Online to Offline Mode
To switch from online mode to offline mode, the “+++” sequence must be sent. Following this, the product
gets back to offline mode with an “OK” response, and an AT command can be sent.
Note: the “+++” sequence only works with the +ICF command using the following settings:
• 8 data bits, with no parity
• 7 data bits, with even parity

CHAPTER 12 - PHONE BOOK COMMANDS
In this chapter, the AT commands are used to operate on mobile phonebook. These phonebook commands
adhere to the set defined in GSM 07.07 specification. Please refer to GSM 07.07 for further AT command
usage and description.
For all phonebook read commands (+CPBR, +CPBF, +CPBP), the TON/NPI MSB of each number is set to 1
(ex: a TON/NPI stored as 17 is displayed as 145).
When accessing numbers in the call history phonebooks (“LD”, “MC”, or “RC”), if a matching number is found
in one of the other phonebooks, the text portion of the matching entry is copied to the call history entry.
The phone book “SM” is only supported in an RUIM capable modem.
When an RUIM is present, the “MT” phonebook is a combination of two phonebooks as shown in the
example below. This must be taken into account when using a phone book AT command index to access an
entry in this phonebook.
ME Index range 1 to 100
SM Index range 1 to 150 (SIM card)
MT ME start at 1, SM start at 101 (SIM

Note: 18 neighbor cells are present. The first neighbor cell band class is
0, its PilotPN is 268, and its frequency assignment is 384.
The value displayed for Ec/Io is the index of the Active set in 0.5dB steps from 0 (0dB) to 63 (-31.5dB). For
example: 0 = 0dB, 1 = 0.5dB, 2 = 1dB, … 62 = 31dB, 63 = 31.5dB
If the <requested dump> parameter is not specified, the <requested dump> value from the previous +CCED
command will be used. If no previous +CCED <requested dump> value is available, a default value of 13 (8,
4, and 1) will be used.
For <requested dump> 4, 2, and 1, the requested information is output using the unsolicited +CCED
response. Place holders are used in the +CCED output for fields that cannot be measured or are not
meaningful in the current mode of operation. In this case, consecutive commas will be present in the output.
There are also several optional parameters ([]) that are not displayed in AMPS mode and will result in place
holders in the +CCED command output. Automatic snapshots of these dumps are not supported during
communication or registration.
For <requested dump> 8, the information is output using the unsolicited +CSQ response. The 07.07 format
of the +CSQ response is respected. However, the <fer> portion of the +CSQ response is not evaluated by
this dump request so the <fer> value will always be 99. Automatic snapshots are supported in idle mode and
during communication.
The combination of multiple <requested dump> values (addition of the values) in a single +CCED command
is supported with the exception of <requested dump> 2. The <requested dump> 2 value must be use by
itself and not in combination with other dump request values.
Either or both the +CCED and +CSQ responses are used for output depending upon the <requested dump>
value. Activation or deactivation of a +CCED response flow will not affect an existing +CSQ response flow.
Likewise, activation or deactivation of a +CSQ response flow will not affect an existing +CCED response
flow.

Play Tone +WTONE
Description: This specific command allows a tone to be played on the current speaker or on the buzzer.
Frequency, volume and duration can be set.
Values: <mode>
0: Stop playing.
1: Play a tone
<dest>: This parameter sets the destination (mandatory if <mode>=1)
1: Speaker
2: Buzzer
<freq>: This parameter sets tone frequency (in Hz) (mandatory if <mode>=1). The range is
between 1 and 4000Hz. However, for handset and a person to hear, the effective range may
be 150-4000Hz.
<volume>(0-3): This parameter sets the tone volume. The default value is 1. Values are the
same as +CRSL.
<duration> (0-50): This parameter sets tone duration (unit of 100 ms). When this parameter
is equal to 0 (default value), the duration is infinite, and the tone can be stopped by
Syntax: Command syntax: AT+WTONE=<mode>[,<dest>,<freq>,<volume>,<duration>]

Play DTMF Tone +WDTMF
Description: This specific command allows a DTMF tone to be played on the current speaker. DTMF,
volume and duration can be set. This command is only used to play a DTMF tone. To send a
DTMF over the CDMA network, use the +VTS command.
Values: <mode>
0: Stop playing.
1: Play a DTMF tone
<dtmf>: This parameter sets the DTMF to play in {0-9,*,#,A,B,C,D} (mandatory if
<mode>=1)
<volume> (0-3): This parameter sets tone gain. The values are identical to those of the
+WTONE (speaker) command (mandatory if <mode>=1).
<duration> (0-50): This parameter sets the tone duration (unit of 100 ms). When this
parameter is 0 (default value), the duration is infinite, and the DTMF tone can be stopped by
AT+WDTMF=0.

Hardware Version +WHWV
Description: This command displays the MSM version along with hardware version number.
MSM version display format: Major.Minor; e.g. 240.16
Major: 240 denotes MSM
Minor: 1 denotes 5105; 06 denotes typeout version 6;
The three-digit production hardware version is written to the modem during manufacturing.
First digit represents PCB version (ex: 5. as in V5). The second and third digits represent
last two digits of part-list number (ex. 04). In this case the hardware version number will be
504.
If the hardware version has not been written by manufacturing second filed of this command
will be 0.
