What should you confirm first when your iPhone status bar displays “SOS " ?

An SOS indication in the iPhone status bar means the device is not connected to its normal cellular network, although emergency calling may still be possible through another available network. The first fundamental check is therefore whether the iPhone is currently in an area where cellular service is available. Apple’s troubleshooting guidance for SOS, No Service, or Searching begins with cellular-network availability and reconnection steps. Low Power Mode does not normally prevent cellular registration, Wi-Fi Assist relates to supplementing weak Wi-Fi with cellular data, and Do Not Disturb affects notifications rather than network registration. If cellular coverage should be available, subsequent steps can include toggling Airplane Mode, restarting the iPhone, checking cellular settings, and contacting the carrier. Therefore, option D is the correct first confirmation.
