On an iPhone, when you see "SOS" or "SOS Only" in the status bar, it means your device is not connected to your usual cellular network, but it can still make emergency calls. This happens when your iPhone loses connection to your carrier but detects another network that allows emergency calls only, such as 911 in the U.S. or other local emergency numbers depending on your location
. Key points about the SOS status on iPhone:
- Limited Connectivity: You cannot make normal calls, send texts, or use mobile data through your carrier. Only emergency calls are possible.
- Automatic Activation: The SOS mode activates automatically when your iPhone detects no service from your carrier but finds another network for emergency calls.
- Common Causes: Poor network coverage (remote areas, underground, buildings with thick walls), carrier outages, SIM card issues, or roaming/international travel where your carrier has no service.
- Emergency Access: Your iPhone can connect to any available cellular network for emergency calls, bypassing your usual carrier restrictions.
- How to Fix: Move to an area with better coverage, restart your iPhone, toggle Airplane Mode on and off, or check for carrier/settings updates.
Additionally, on newer iPhone models (iPhone 14 and later), if no cellular network is available, you might see Emergency SOS via Satellite, allowing emergency calls via satellite
. In summary, "SOS" on your iPhone signals that normal cellular service is unavailable, but you can still reach emergency services through another network
