Core AT Commands
The G24 responds to a limited commands set when the SIM card is not functioning, or not
present. These commands are referred to as the "Core AT commands".
In previous products, the Core AT commands were called "Basic AT commands". The name
"Core" differentiates between the basic AT commands format and the limited service AT
commands.
The following table lists the Core AT commands.
