Introduction
This document lists and describes the AT Command Set to be used in conjunction with the Novatel
Wireless MiFi 4G LTE Global USB Modem U620L.
Platform Reference and Use
In this document, the device may be referred to using various terms, such as MS (Mobile Station), TA
(Terminal Adapter), DCE (Data Communication Equipment), or ME (Mobile Equipment).
You can control the device on a DTE (Data Terminal Equipment) platform by issuing the AT commands
through a serial interface.
Command Syntax
The attention or “AT” prefix is required prior to entering any command. All commands require a carriage
return or <CR> following the entry of the command. All command responses are encapsulated by a
carriage return and line feed or <CR><LF>. The ASCII display of these characters is suppressed with
only the modem response being presented.
In addition to terminating AT commands, you can use the carriage return <CR> to abort commands
that are executing.
Most AT commands complete immediately so there is no opportunity to abort them, for instance ATI.
However, some commands like AT+COPS or AT+CFUN can take several seconds to complete. The AT
command interface is said to be in execution mode when a command is running and has not returned a
result code (OK/ERROR). A second <CR> entered while the AT command interface is in execution mode
aborts the command and returns the interface to command mode.
Some AT commands require additional input, for instance AT+CMGS. After terminating the AT+CMGS
command with a <CR> the AT command interface enters line edit mode. While in line edit mode all
characters are accepted except CNTL-Z. CNTL-Z terminates line edit mode and the AT command
interface enters execution mode. Like before, at this point another <CR> aborts the command.

You can concatenate an ATmessage using the semicolon (;) between commands.
The following examples demonstrate the potential usage of AT commands presented:
Type Example Description
Command Format Query AT+GXXX=? Returns the command format and value
ranges.
Command Read AT+GXXX? Returns the current value assigned to the
command.
Command Write AT+GXXX=<value>,<value>, Sets the command to specified value(s).
Command Execution AT+GXXX Executes the specified command.
Command
Concatenation
AT+CRC=1;S0=1 Executes both the CRC and S0 command.

Notes (Additional command notes)
Examples
NOTE: Where applicable, the <value> responses provided for the READ and EXECUTE formats are
modem default values. All efforts will be made by Novatel Wireless. to keep these values current in the
documentation but will not be responsible for any differences that may occur as a result subsequent
software builds and version enhancements.
WARNING! Do not use tab characters in the custom AT command scripts.
