Command Types
Note: The AT prefix does not
appear in the reference tables. It
is, however, required and
assumed for all commands
unless specifically noted
otherwise.
The command reference table (beginning on page 31) details
the available AT commands in strict ASCII alphabetic order
(including character prefixes such as
!, & and +, which in ASCII
fall before the letters of the alphabet). Sections preceding those
tables outline how the commands are organized into
functional groups, including:
• Standard modem commands, beginning on page 24.
• GSM voice and circuit-switched data from page 26.
• SMS commands, page 27.
• GPRS packet data commands, page 28.
• EDGE packet data commands, page 28.
Within each functional section, commands also appear in
ASCII alphabetic order, with a cross-reference to the full
description in the reference table. This format allows quick
lookup of each command to verify syntax, parameters, and
behaviors.
Standard Modem Commands (V.25ter)
Sierra Wireless GSM/GPRS devices support most of the
standard AT commands used by telecommunications software
for over twenty years.
The following commands are derived from the original 1981
Hayes AT landline modem command set, with some
additional commands specific to wireless devices.
These commands have been standardized by the International
Telecommunications Union (ITU) as ITU-T recommendation
V.250 (also known as V.25ter). You can find more information
on the standard at
www.itu.int.
