Have you ever looked at the top of your iPhone and seen “SOS” or “SOS Only” next to your signal bars? Don’t panic — your phone isn’t broken, but it does mean there’s an issue with your cellular network connection.

In this guide, we’ll explain what “SOS” mode is, why it appears, and how to fix it.

❓ What Is “SOS” or “SOS Only” on iPhone?

When your iPhone displays “SOS” or “SOS Only” in the status bar, it means:

• You’re not connected to your carrier’s network.
• You can still make emergency calls (e.g., 112, 911, etc.).
• It typically occurs in areas with limited or no service, or when there’s a SIM or network issue.

This feature is part of Apple’s safety design, ensuring you can still call for help even without a mobile signal from your provider.

🔍 Why Your iPhone Shows “SOS”

Here are the most common reasons:

1. Poor or No Cellular Coverage: You’re in a remote or blocked area.
2. SIM Card Issues: Your SIM may be dislodged, damaged, or inactive.
3. Carrier Problems: Network outages or unpaid bills can lead to a service block.
4. Network Settings Misconfigured: Incorrect settings can affect connectivity.
5. Software Bugs or iOS Glitches: Sometimes, a quick restart fixes the issue.
