Important
Notice
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
operator's control and operation of that vehicle. In some states and provinces,
operating such communications devices while in control of a vehicle is an offence.
Limitation of
Liability
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 SPECIFICALLY DISCLAIM LIABILITY FOR ANY AND ALL
DIRECT, INDIRECT, SPECIAL, GENERAL, INCIDENTAL, CONSEQUENTIAL,
PUNITIVE OR EXEMPLARY DAMAGES INCLUDING, BUT NOT LIMITED TO,
LOSS OF PROFITS OR REVENUE OR ANTICIPATED PROFITS OR REVENUE
ARISING OUT OF THE USE OR INABILITY TO USE ANY SIERRA WIRELESS
PRODUCT, EVEN IF SIERRA WIRELESS AND/OR ITS AFFILIATES HAS BEEN
ADVISED OF THE POSSIBILITY OF SUCH DAMAGES OR THEY ARE
FORESEEABLE OR FOR CLAIMS BY ANY THIRD PARTY.
Notwithstanding the foregoing, in no event shall Sierra Wireless and/or its
affiliates aggregate liability arising under or in connection with the Sierra Wireless
product, regardless of the number of events, occurrences, or claims giving rise to
liability, be in excess of the price paid by the purchaser for the Sierra Wireless
product.

1: About This Guide
Introduction
This document describes supported standard and proprietary AT
commands available for Sierra Wireless AirPrime®WP products, and
provides details where commands vary from the standards.
Important: This document applies to the following WP Series module
groups (as of date of publication): WP85xx, WP75xx, WP76xx, WP77xx.
These commands are intended for use by OEMs, and are
supplemental to the standard AT commands for GSM devices defined
by the 3GPP (3rd Generation Partnership Project) in TS 27.007 AT
command set for User Equipment (UE) and 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).
Note: For questions or concerns relating to command implementation,
please contact your Sierra Wireless account representative.
Command access
Some commands in this reference are password-protected. To use
these commands, enter the correct password using AT!ENTERCND
on page 26. Once the password is entered, all commands are
available and remain available until the modem is reset or powered
off and on.
The password assigned to !ENTERCND is unique to each customer
and is configured onto the modem during manufacture. If you do not
know your password, contact your Sierra Wireless Account Manager
or Sierra Wireless distributor.
Command timing
Interval timing
Some commands require time to process before additional
commands are entered. For example, the modem returns OK when it
receives AT!DAFTMACT. If AT!DASBAND is received too soon after
this, the modem returns an error.

When building automated test scripts, ensure that sufficient delays are
embedded, where necessary, to avoid these errors.
Escape sequence guard time
The AT escape sequence “+++” requires a guard time of 1.0 seconds before and
after it is used.
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 is returned
if the command is not recognized or is not permitted in the current state or
condition of the modem.
Response formats
Response formats shown in this document are intended to accurately describe
the non-whitespace content of responses. For display purposes within this
document, extraneous whitespace content (blank lines between lines of text) may
not be displayed, and whitespace (blank spaces) between text segments within
lines may be shorter or longer than what is received in actual responses.
For example:
If automated scripts are used to parse command responses, make sure to parse
whitespace appropriately.
