Note: Some standard 3GPP commands are NOT supported, or are
partially supported. These commands are identified in
Supported
GSM / WCDMA AT Commands, page 17.
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
