Preface
Important Notice
Limitation of
Liability
Due to the nature of wireless communications, transmission and reception of data can never be guaranteed. Data may be delayed, corrupted (i.e., have errors) or be totally lost.
Although significant delays or losses of data are rare when wireless devices such as the Sierra Wireless modem are used in a normal manner with a well‐constructed network, the Sierra
Wireless modem should not be used in situations where failure to transmit or receive data could result in damage of any kind to the user or any other party, including but not limited to personal injury, death, or loss of property. Sierra Wireless accepts no responsibility for damages of any kind resulting from delays or errors in data transmitted or received using the
Sierra Wireless modem, or for failure of the Sierra Wireless modem to transmit or receive such data.
Safety and Hazards
Do not operate the Sierra Wireless modem in areas where blasting is in progress, where explosive atmospheres may be present, near medical equipment, near life support equipment, or any equipment which may be susceptible to any form of radio interference. In such areas, the Sierra Wireless modem
MUST BE POWERED OFF. The Sierra Wireless modem can transmit signals that could interfere with this equipment.
Do not operate the Sierra Wireless modem in any aircraft, whether the aircraft is on the ground or in flight. In aircraft, the
Sierra Wireless modem MUST BE POWERED OFF. When operating, the Sierra Wireless modem can transmit signals that could interfere with various onboard systems.
Note: Some airlines may permit the use of cellular phones while the aircraft is on the ground and the door is open. Sierra Wireless modems may be used at this time.
The driver or operator of any vehicle should not operate the
Sierra Wireless modem while in control of a vehicle. Doing so will detract from the driver or operatorʹs control and operation of that vehicle. In some states and provinces, operating such communications devices while in control of a vehicle is an offence.
The information in this manual is subject to change without notice and does not represent a commitment on the part of
Sierra Wireless. SIERRA WIRELESS AND ITS AFFILIATES

Introduction
This document describes standard and proprietary AT commands that are available for users of UMTS AirCard modems and Mini Card embedded modules.
The standard 3GPP AT commands for UMTS devices are described in two standards documents available from the
3GPP (3rd Generation Partnership Project) web site, www.3gpp.org
:
•
TS 27.007 AT command set for User Equipment (UE)
•
TS 27.005 Use of Data Terminal Equipment ‐‐ Data Circuit
terminating Equipment (DTE‐DCE) interface for Short Message
Service (SMS) and Cell Broadcast Service (BSE)
The proprietary AT commands are supplemental to the standard AT commands.
For normal operation of the modem, consult the GSM AT
Command Reference (document number 2130213). You may also want to consult the other documents available in the AC8xx/
MC87xx Development Kit or on our Internet site at www.sierrawireless.com
Note: Some standard 3GPP commands are NOT supported, or are
partially supported. These commands are identified in Supported
GSM / WCDMA AT Commands , page 15 .

Note: When designing applications that use these AT commands, use
Watcher
®
(and other Sierra Wireless applications) as functionality templates to ensure proper use of command groups. For questions or concerns relating to command implementation, please contact your
Sierra Wireless account representative.

Note: Revision codes that include letters, such as 2.1A, are to be considered drafts and are subject to change before final release.
Result codes
Result codes are not shown in the command tables unless special conditions apply. Generally the result code
OK
is returned when the command has been executed.
ERROR
may be returned if parameters are out of range, and will be returned if the command is not recognized or is not permitted in the current state or condition of the modem.
Terminology and acronyms
This document makes use of acronyms that are in common use in data communications and cellular technology. Our Internet site provides a Glossary of Terms and Acronyms (document number 2130891) that may be helpful in understanding some acronyms and terminology used in this guide.

Conventions
The following format conventions are used in this reference:
Character codes or keystrokes that are described with words or standard abbreviations are shown within angle brackets using a different font, such as
<CR>
for Carriage Return and
<space>
for a blank space character.
Numeric values are decimal unless prefixed as noted below.
Hexadecimal values are shown with a prefix of 0x, i.e. in the form 0x3D.
Binary values are shown with a prefix of 0b, i.e. in the form
0b00111101.
Command and register syntax is noted using an alternate font:
!CHAN=<c>[,b]
. The “
AT
” characters are not shown but must be included before all commands except as noted in the reference tables.
Characters that are required are shown in uppercase; param‐ eters are noted in lowercase. Required parameters are enclosed in angle brackets (
<n>
) while optional parameters are enclosed within square brackets (
[x]
). The brackets are not to be included in the command string.
Commands are presented in table format. Each chapter covers the commands related to that subject and presents a summary table to help you locate a needed command. Commands are in
ASCII alphabetical order in the body of each chapter.
Any default settings are noted in the command tables. Note that these are the factory default settings and not the default parameter value assumed if no parameter is specified.
12 2130617
Result Code
This is a numeric or text code that is returned after all commands (except resets). Only one result code is returned for a command line regardless of the number of individual commands contained on the line.
Response
This term indicates a response from the modem that is issued prior to a result code. Reading registers or issuing commands that report information will provide a response followed by a result code unless the command generates an error.
Responses and result codes from the modem, or host system software prompts, are shown in this font:

Commands
This chapter identifies which ITU‐T Recommendation V.250,
3GPP TS 27.005, and 3GPP TS 27.007 AT commands are supported on regular and voice‐enabled Sierra Wireless
AirCard modems (850/860/875/880/881) and Mini Card embedded modules (MC8755/65/75/80/81). These commands are used to:
•
Control serial communications over an asynchronous interface (ITU‐T Recommendation V.250)
•
Control SMS functions for devices on GSM/WCDMA networks (3GPP TS 27.005)
•
Control devices operating on GSM/WCDMA networks
(3GPP TS 27.007)
The ITU‐T specification, Serial Asynchronous Dialling and
Control (Recommendation V.250), is available on the International
Telecommunication Union web site, www.itu.int
, and the
3GPP specification documents, 3GPP TS 27.007 V3.13.0 (2003‐
03) and 3GPP TS 27.007 V3.13.0 (2003‐03), are available on the
3GPP web site, www.3gpp.org
.
The tables below identify whether each command is supported on AirCard modems and Mini Card embedded modules. An
“N/A” in the Supported column of the table indicates that the command is related to a feature (such as voice) that is not available on the modems.
Some commands are partially supported—the descriptions for these commands identify any limitations on command usage.
Also, some commands are described in more detail in later chapters—the descriptions for these commands link to those
detailed entries (for example, &V in Table 1).

Queries / sets SMS retry period and interval
This command is used to configure the SMS retry period and interval for
MO-SMS.
Usage:
•
AT!SMSRETRY? returns the current <period> and <interval> settings.
•
AT!SMSRETRY=? reports the format used for AT!SMSRETRY.
•
AT!SMSRETRY=<period>, <interval> sets the retry period and retry interval
Parameters:
<period> (Number of seconds allowed for MO-SMS retry attempts):
•
0–255
<interval> (Number of seconds to wait between MO-SMS retry attempts):
•
0–255
Note: If <interval> is greater than <period>, a single retry attempt is made.
Note: <interval> ignores the time spent actually performing a retry attempt. If <interval> = 5, attempts are made at elapsedTime = 0, 5, 10, etc. until an attempt is successful or <period> - elapsedTime < <interval>.
Example 1:
Assume a retry attempt takes 2 seconds.
If <period> = 1 and <interval> = 8, and no attempts are successful:
•
time = 0: Retry attempt fails at time = 2. No more attempts are made because <period> has expired.
Example 2:
Assume a retry attempt takes 2 seconds.
If <period> = 3 and <interval> = 5, and no attempts are successful:
•
time = 0: Retry attempt fails at time = 2. No more attempts are made because <period> will expire before the <interval> passes.
Example 3:
Assume a retry attempt takes 2 seconds.
If <period> = 14 and <interval> = 5, and no attempts are successful:
•
time = 0: Retry attempt fails at time = 2; next attempt will begin at time=5 (the <interval> counts from the beginning of the previous attempt)
•
time = 5: Retry attempt fails at time = 7; next attempt will begin at time=10
•
time = 10: retry attempt fails at time = 12; No more attempts will be made because the <period> will expire before another <interval> of 5 seconds can pass.

Supporting modems:
•
All
Enables / disables ciphering and integrity settings
To register onto a network with WCDMA service, the modem’s ciphering and integrity settings must be enabled or disabled to match the network settings. Most carriers enable both ciphering and integrity.
When testing the modem, you may be using a SIM that has different codes for ciphering and integrity than those used by the test system. In this case, you may need to disable ciphering and integrity checking to use the test system.
Usage:
•
AT!GCIPHER=<setting> sets the ciphering and integrity settings.
•
AT!GCIPHER? reports the current ciphering and integrity settings
(0=disabled, 1=enabled).
Parameters:
<setting> (enable / disable ciphering and integrity):
•
0 = ciphering disabled; integrity disabled
•
1 = ciphering enabled; integrity disabled
•
2 = ciphering enabled; integrity enabled
