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, this CDMA AT command set is designed to cover the following:

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 GSMrelated commands.

Scope of This Document

This document describes CDMA AT commands, their syntax, responses, and result codes. It serves as the reference for wireless application development based on the CDMA modem and for its integration and testing. The intended audience is expected to be familiar with CDMA data services protocol and AT modem commands.

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 21. 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

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. Note 2: <band> 1 (PCS) is not available in RUIM software versions.

Values: The parameter values are the following ones: <band>

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 non-volatile 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.

Chapter 6 – SIM Card Operational Commands

Chapter 6 – 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 Respon ses

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:

Chapter 6 – 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 8 digits.

Syntax: Command syntax: AT+CPIN2=<pin2>

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 syntax: AT+CPIN2=<puk2>,<NewPin2>

Command Possible Responses

AT+CPIN2=00000000,1234 Note: Enter PUK2 and new PIN2 AT+CPIN2=12345678,1234 Note: Enter PUK2 and new PIN2, 2nd attempt

To ascertain which code must be entered (or not), the following query command can also be used: AT+CPIN2?

The possible responses are:

+CPIN: READY ME is not pending for any password +CPIN: UIM PIN2 CHV2 is required +CPIN: UIM PUK2 PUK2 is required +CME ERROR: <err> SIM failure (13) absent (10) etc.

The product requires that the PIN2 code be successfully entered in order to write a entry into the Fix Dialing

Phonebook (FDN).

Command Possible Responses

AT+CPBS=”FD” Note: Select Phonebook FDN AT+CPBW=5,”12345678”,145”test1” Note: Write entry 5 in the FDN AT+CPIN2=1234 Note: Enter PIN2 AT+CPBW=5,”12345678”,145”test1” Note: Write entry 5 in the FDN

+CME ERROR: 16 Note: Incorrect PUK2 OK Note: PUK2 correct, new PIN2 stored

OK +CME ERROR: 17

Note: PIN2 not yet entered OK Note: PIN2 successfully entered OK Note: Command now successful

PIN Remaining Attempt Number +CPINC

Description: This command is used to get the number of valid attempts for PIN1 (CHV1), PIN2 (CHV2), PUK1

(UNBLOCK CHV1) and PUK2 (UNBLOCK CHV2) identifiers.

Values: <n1>, <n2> are the attempts left for PIN1, PIN2 (0 = blocked, 3 max) <k1>, <k2> are the attempts left for PUK1, PUK2 (0 = blocked, 10 max)

For this to work, the card should be present at the time of initialization. Otherwise, an error will be sent

(+CME ERROR: 10).

Syntax: Command syntax: AT+CPINC Response syntax: +CPINC: <n1>,<n2>,<k1>,<k2>

Chapter 8 – Supplementary Services Commands

Chapter 8 – 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 produced in the audio path to confirm the change of the call forwarding state.

Values: <number> The phone number to forward all calls to.

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.

Syntax: Command syntax: AT+CCFC= <number>

Command Possible Responses

ATD*72 Note: Specify the call forwarding prefix number.

AT+CCFC=8585551212 Note: Register to an unconditional call forwarding.

AT+CCFC=0 Note: Cancel unconditional call forwarding

OK Note: Prefix number set.

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: 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. AT+CLIR? Note: Ask for current functionality

OK Note: Command valid +CLIR :<mode> OK Note: <mode> as defined below

Chapter 8 – Supplementary Services 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.

Syntax: Command syntax: AT+WFSH

Command syntax AT+WFSH= < phone_number > (for a flash with information)

Chapter 11 – 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.

Chapter 12 – Position

Determination (GPS)

Commands

The position determination AT commands are supported on gpsOne equipped CDMA modules. GpsOne is a wireless-assisted hybrid solution that utilizes both GPS and base-station trilateration to determine the mobile position. A high degree of position accuracy is possible using gpsOne due to the inclusion of CDMA system timing information in the position calculation.

The gpsOne feature includes a number of AT commands that are used to configure, start, stop, and report position data. The reported position data is used by the user or application software host to provide the desired features. GpsOne functionality is dependent on the carrier and network configurations. A number of gpsOne session examples are included in section 21 to aide in the understanding of the gpsOne AT commands.

Position Determination Session Type +WPDST

Description: This command sets the desired position determination session type. The session type specifies how the

next PD session is to function. An attempt to change the session type while a PD session is in progress will result in an error.

0 Session to provide the last position info available. Position fix not performed. 1 Session to provide single-shot fix. Perform a new position fix. 2 Tracking mode independent fixes; session to provide continuous independent position fixes. 3 Tracking mode; session to provide continuous position fixes. 4 Data download; session to download ephemeris/almanac data only. Used for MS-based fix

determination. Download data is valid for 30 to 120 minutes.

Note: When a tracking mode is requested (continuous position fixes) and the TCP/IP transport layer is used, a

data call will interrupt the reception of position fixes. The modem will store up to 10 of the most current position fixes and present them when the data call ends.

Cell Environment and RxLev Indication +CCED

Description: This command can be used by the application to retrieve information about the main cell and up to six

neighboring cells. This is an extended command that may be used in two different settings:

1. Interrogation of the cell environment information

2. Interrogation of the received signal strength indication (RSSI)

The +CCED command supports two modes of operation: on request by the application or automatically by the product every 5 seconds.

Values: <mode>

0 Requests a single snapshot of cell data 1 Start automatic snapshot mode 2 Stop automatic snapshot mode

Automatic snapshot mode will not return a terminating “OK”. The unsolicited responses +CCED and/or +CSQ will be used to return the requested information.

1 Main Cell: <mode>, <band class>, <Channel #>, SID, NID, <Base Station P Rev>, [<Pilot PN offset>],

2 Neighbor1 to Neighbor20 (max): The first value is the <number of neighbor entries> in the response.

Each neighbor entry consists of the following values: <band class>, [<Pilot PN>], <Frequency Assignment>

4 Timing Advance: Always zero for CDMA 8 Main cell RSSI indication (RxLev) from 0 to 31.

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 analog mode and will result in place holders in the +CCED command output. Automatic snapshots of these dumps is not supported during communication or registration.

For <requested dump> 1, the first value output in the unsolicited +CCED response is the +CCED command specified <mode> (0, 1, or 2). 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. The value displayed for <Rx power>, <Tx power>, and <Tx Adj> is in terms of dBm.

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.

Configure LED Indicator +CLED

Description: This command is used to configure GPIO 41 and GPIO 54 for general purpose use. The default use of these

two GPIO’s is to drive LED indicators on the Developer Kit board. This command allows a user application to disable this default behavior. When disabled, the user application has full control over the state of these GPIO’s. The modem operating software will be prevented from change them for operational status indications.

The byte value specified with the +CLED command is a bitmap where bit 0 configures LED1/GPIO 41 and

bit 1 configures LED2/GPIO 54. Bit positions 2 through 7 are ignored.

The state of the +CLED specified control bits is not persistent. Both bit positions are always set active (1)

during boot resulting in LED status indicator operation. The +CLED command must be used by the user application after each boot if GPIO 41 or GPIO 54 are used for other purposes.

Values: <bitmap value>

bit 0 0 = GPIO 41 selected; 1 = LED1 selected. bit 1 0 = GPIO 54 selected; 1 = LED2 selected. bit 2 – bit7 Reserved

Chapter 14 – SIM ToolKit

Chapter 14 - SIM ToolKit for

RUIM Software Version

Overview of SIM Application ToolKit

Note: The SIM ToolKit features and functionality are available only in the RUIM software version. Summary

SIM ToolKit, also known as .SIM Application ToolKit, introduces new functionalities which open the way to a broad range of value added services. The principle is to allow service providers the ability to develop new applications (e.g. banking, travel, ticket booking, etc.) for subscribers and to download them into the SIM. This solution allows new services to be accessible to the user by adding new SIM-based applications without modifying the handset.

Functionality

SIM Toolkit refers to the functionalities described in the GSM Technical specification 11.14. It introduces about 25 new commands for the SIM. Three classes of ToolKit functionalities have been defined with class 1 offering a subset of commands and class 3 offering the full range of commands. The SIM Application Toolkit supports:

• Profile Download

• Proactive SIM

• Data Download into SIM

• Menu Selection

• Call Control by SIM

Profile Download

The Profile Download instruction is sent by the customer application to the SIM as part of the initialization. It is used to indicate which SIM Application Toolkit features the customer application supports.

The AT command used for this operation is +STSF (SIM ToolKit Set Facilities).

Proactive SIM

A proactive SIM provides a mechanism whereby the SIM can ask the customer application to perform certain actions. These actions include:

• display menu

• display given text

• get user input

• send a short message

• play the requested tone

• set up a call

• provide location information

This mechanism allows SIM applications to generate powerful menu-driven sequences on the customer application and to use services available in the network. The commands used for this operation are:

+STIN (SIM Toolkit Indication) +STGI (SIM Toolkit Get Information) +STGR (SIM Toolkit Give Response)

Data Download to SIM

Data downloading to the SIM allows data (SMS, phonebook) or programs (Java applets) received by SMS or by Cell Broadcast to be transferred directly to the SIM Application.

This feature does not need any AT command. It is transparent to the customer application.

Menu Selection

A set of menu items is supplied by the SIM Application ToolKit. The menu selection command can then be used to inform the SIM Application which menu item is selected. The commands used for this operation are:

+STIN (SIM Toolkit Indication) +STGI (SIM Toolkit Get Information) +STGR (SIM Toolkit Give Response)

Multi-Tech Systems, Inc. CDMA Wireless AT Commands (PN S000294J) 89

Chapter 14 – SIM ToolKit

Call control by SIM

The call control mechanism allows the SIM to check all dialed numbers, supplementary service control strings and USSD strings before connecting to the network. This gives the SIM the ability to allow, bar or modify the string before the operation starts. The commands used for this operation are:

+STCR (SIM Toolkit Control Response) +STGR (SIM Toolkit Give Response)

Messages Exchanged During a SIM ToolKit Operation

The following scheme shows the SIM Toolkit commands and unsolicited results that are exchanged.

Step One

The customer application informs the modem which facilities are supported. This operation is performed with the +STSF (SIM ToolKit Set Facilities) command, which is also used to activate or deactivate the SIM Toolkit functionality.

Step Two

An unsolicited result +STIN (SIM ToolKit indication) is sent by the product to indicate the customer application which command type the SIM Application Toolkit is running on the SIM card. The last SIM Toolkit indication can be requested by the +STIN? command.

Step Three

The customer application uses the +STGI (SIM ToolKit Get Information) command to get all the information about the SIM ToolKit command, given by +STIN.

Step Four

The customer application uses the +STGR (SIM Toolkit Give Response) to send its response (if any) to the SIM ToolKit Application.

The +STCR (SIM Toolkit Control response) indication is an unsolicited result sent by the SIM when call control functionality is activated and before the customer application has performed any outgoing call, SMS, SS, or USSD.

SIM ToolKit Set Facilities +STSF

Description: This command allows SIM ToolKit facilities to be activated, deactivated or configured. Values: <mode>

0 Deactivates the SIM Toolkit functionalities. 1 Activates the SIM Toolkit functionalities. 2 Configures the SIM Toolkit functionalities.

The activation or deactivation of the SIM Toolkit functionalities requires the use of the +CFUN (Set phone functionality) command to reset the product. +CFUN is not necessary if PIN is not entered yet.

(160060C01F . 5FFFFFFF7F) (hex format) The <Config> parameter gives the coding of the TERMINAL PROFILE, precisely the list of SIM

Application Toolkit facilities that are supported by the customer application.

1-255: Timeout for user responses (multiple of 10 seconds).

The <Timeout> parameter (multiple of 10 seconds) sets the maximum time the user has for reacting (to

select an item, to input a text, etc).

0 Automatic response is not activated 1 Automatic response is activated

When the <Autoresponse> is activated, the +STIN indication for Play Tone (5), Refresh (7), Send SS (8), Send SMS (9) or Send USSD (10) is automatically followed by the corresponding +STGI response.

Note: Some bits are related to the product only and not to the customer application. The product automatically sets

these bits to either 0 or 1 whatever the user enters with the +STSF command. Each facility is coded on 1 bit:

• .bit = 1: facility is supported by the customer application.

• .bit = 0: facility is not supported by the customer application.

Only the first five bytes of the TERMINAL PROFILE (Class 2) can be configured; the other are set to 0.

Chapter 15 – Provisioning AT

Commands

Introductory Note

This chapter covers general CDMA provisioning commands; provisioning commands let you setup your service programming code, your mobile directory number, your browser gateway, your service options, etc. Some of the commands that follow will be useful for the average wireless user; others will be useful to programmers only. Some parameters or commands discussed in this chapter may be re-defined by your network carrier. Your carrier will provide these commands for you. See also the printed Activation Notices that accompany the Multi-Tech wireless products.

What is Provisioning?

The Difference Between a Pre-Provisioned CDMA Module and a Generic CDMA Module

Pre-Provisioned CDMA Modules

Multi-Tech offers several pre-provisioned CDMA modules. Pre-provisioned builds are pre-programmed to operate only on a designated CDMA carrier’s network; for example, the MTSMC-C-N2 is pre-programmed (provisioned) for use on the Sprint network in the USA.

Generic CDMA Modules

Multi-Tech also offers generic CDMA modules, for example, the MTSMC-C-N1 (Random A-Key) and MTSMC-C- N9 (Zero A-Key). These generic SocketModems are not pre-programmed to operate on any designated CDMA carrier’s network.

Overview of the Provisioning Process

Requirements

• A generic CDMA module.

• CDMA AT Commands Reference Guide, Chapter 15.

• A developer software tool called WPST.

Procedures

Step 1. Get the PRI and PRL from your wireless carrier. Step 2. Set the provisioning commands, which are described in the AT Commands Reference Guide

using the provisioning information provided by the CDMA wireless network carrier.

Step 3. Using the WPST tool, download the carrier’s specific PRI (Provisioning Information) and PRL

(Preferred Roaming List) into the CDMA module.

The wireless modem is now provisioned and can be activated on your wireless carrier’s network, according to the carrier’s activation instructions. See the Activation directions that accompany Multi-Tech wireless modems.

Provisioning Terminology

A-Key

The A-Key is a 64-bit cryptographic key variable stored in the semi-permanent memory of the mobile station and also known to the Authentication Center of the wireless carrier's system. The generation of the A-Key is the responsibility of the wireless service provider. It is established and entered when the mobile station is first put into service.

The CDMA network carrier you choose for you CDMA product will let you know whether it uses the Random A-Key or the Zero A-Key in its authentication process. That will determine whether you purchase the -N1 or the –N9 build.

Provisioning

Provisioning is the programming of a CDMA wireless modem to set the PRI and PRL provided by wireless network carrier that you are have chosen as your CDMA wireless network carrier. After the modem is provisioned, it can then be activated on the wireless network for which it is provisioned.

PRI stands for Provisioning Information. Provisioning Information is your wireless network carrier’s profile of parameter settings that must be programmed into your wireless modem in order for it to operate on the carrier’s wireless network.

PRL stands for Preferred Roaming List. The PRL is a list of the wireless network service provider’s preferred roaming partners. This list is downloaded from your network service provider during the provisioning process.

Chapter 15 – Provisioning AT Commands

Service Programming Code +WSPC

Description: This command allows for entry of the service programming code (either MSL or OTKSL). Upon successful

entry of this code, all other service provisioning AT commands may be used. If this code is not properly entered prior to attempting other provisioning AT commands, all provisioning commands will return ERROR. If the OTKSL is used to enter provisioning mode, only the +WIMI, +WMDN, and +WCMT commands will be allowed. All other commands will return ERROR.

This command supports five attempts to enter the correct service programming code. If five incorrect

attempts are performed, the ME will power down.

Once the correct SPC code is entered, the modem transitions to the Service Programming state. This state

is not exited until a commit is done (+WCMT). While in the Service Programming state, subsequent validations of the SPC code are ignored until the Service Programming state is reset.

Values: <lo ck type>

0 OTKSL – One Time Key Subsidy Lock 1 MSL – Master Subsidy Lock

<code> Six character programming code. Syntax: Command syntax: AT+WSPC=<lock type>,<code>

Command Possible Responses

AT+WSPC? Note: Service programming code request AT+WSPC=? ERROR

AT+WSPC=1,111111 Note: Enter service programming code 111111 AT+WSPC=1,000000 Note: Enter service programming code 000000

ERROR Note: Invalid request

Note: Invalid request ERROR Note: Code invalid OK Note: Code valid

Mobile Directory Number +WMDN

Description: This command is used to enter a new mobile directory number. Valid numbers are between 10 and 15 digits

in length. For support of Wireless Number Portability in all non-RUIM software versions, changes to the MDN will update the IMSI_M portion (least significant 10 digits) of the IMSI. Changes to the MDN will also automatically update the Access Overload Class values unless specifically modified using the +WAOC command. Also, for non-RUIM software loads, the lock code value (+WPIN) is updated to the last 4 digits of the specified MDN value. The new IMSI_M and Access Overload Class values will not be visible in the WIMI and WAOC commands until after the changes are committed with the WCMT command.

Syntax: Command syntax: AT+WMDN=<number>

Command Possible Responses

AT+WMDN? Note: Get current mobile directory number AT+WMDN=8585551212 Note: Set mobile directory number to 8585551212

Note: For RUIM software releases, this command can be used without the need to have previously entered the

SPC (+WSPC command). The value for <number> can be up to 15 digits and does not effect the IMSI.

+WMDN: 8581111111 OK OK

Set IMSI +WIMI

Description: This command is used to set the IMSI. Valid IMSI is 15 digits in length, MCC (3), MNC (2), MIN2 (3), MIN1

(7). For support of Wireless Number Portability, changes to the IMSI will NOT update the MDN. Changes to the IMSI will automatically update Access Overload Class values unless specifically modified using +WAOC.

Syntax: Command syntax: AT+WIMI=<number>

Command Possible Responses

AT+WIMI? Note: Get current IMSI

AT+WIMI=310008585551212 Note: Set IMSI to 310008585551212

Note: For RUIM software releases, this command is not valid and will return “Error 3”.

+WIMI: 310008581111111 OK
