Set command

The command sets the functional mode to Minimum (Power off), Normal, or Offline mode (Flight mode). There is a specific mode for Flight mode with Universal Integrated Circuit Card (UICC) on.


The set command parameters and their defined values are the following:

0 – Power off
1 – Normal mode
4 – Offline mode
44 – Offline mode without shutting down UICC
  • The response to changing to Normal mode could be ERROR if the Subscriber Identity Module (SIM) card has failed.
  • Commanding the device to Power off or to Offline mode might take some time if signaling with the network is needed.
  • When commanding the device to power off, a power cycle is needed and no further AT commands should be sent before that is completed.
