How to Fix “SOS Only” on iPhone (Step-by-Step Troubleshooting Guide)
SOS calling screen on iPhone

If your iPhone suddenly shows “SOS only” in the top bar, it can be worrying - but there’s no need to panic. This message means your phone can only make emergency calls because it’s not connected to your carrier’s mobile network.

The good news is that this issue is almost always temporary, and there are several ways to fix it. In this guide, you’ll learn what “SOS only” means, why it happens, and how to restore your connection quickly - including how using an eSIM provider like Maaltalk can keep you connected even when your physical SIM lets you down.

What Does “SOS Only” Mean on iPhone?

When your iPhone displays “SOS” or “SOS only”, it means your device can’t connect to your usual mobile network - but you can still call emergency numbers like 911 (US), 000 (Australia), or 112 (EU).

This feature is a safety fallback available in certain countries to ensure you’re never completely disconnected during emergencies.

However, “SOS only” also means you can’t use mobile data, send texts, or make normal calls - which can disrupt messaging apps, browsing, and even eSIM activation.

Why Your iPhone Says “SOS Only”

Several factors can trigger the issue, including:

  • Weak or no network coverage in your area
  • SIM card not inserted, damaged, or not recognized
  • Outdated carrier or iOS settings
  • Temporary carrier outage
  • Account or payment issue
  • Network configuration error

Understanding the cause helps you fix it faster and avoid it in the future.

How to Fix “SOS Only” on iPhone

Here are the most effective solutions, from quick fixes to advanced options.


1. Check Your Network Coverage

If you’re in a rural area, basement, or building with thick walls, your iPhone might lose signal temporarily. Try stepping outside or moving near a window to see if the signal returns.

→ Tip: Poor coverage is one of the biggest causes of SOS-only mode. With a global eSIM from Maaltalk, you can switch to a stronger network instantly with no SIM swapping required.


2. Turn Airplane Mode On and Off

This quick toggle refreshes your network connection.


  1. Open Control Center.
  2. Tap the Airplane icon.
  3. Wait 10 seconds, then tap it again.

Your iPhone will reconnect to the carrier network automatically.


3. Restart Your iPhone

Restarting can fix temporary software or signal glitches.

  • Press and hold the Side + Volume button, then slide to power off.
  • Wait a few seconds, then turn your iPhone back on.

4. Reinsert or Check Your SIM Card

Remove the SIM card tray using a SIM tool, wipe the SIM gently, and reinsert it. If the problem persists, your SIM might be faulty and that’s where eSIM technology from Maaltalk becomes a game-changer.


5. Update Carrier and iOS Settings

To check for updates:

  • Go to Settings → General → About (for carrier updates).
  • Go to Settings → General → Software Update (for iOS).

Both updates can fix compatibility issues that cause network drops


6. Reset Network Settings

If your iPhone still shows “SOS only,” try a full network reset.

  1. Go to Settings → General → Transfer or Reset iPhone → Reset → Reset Network Settings.
  2. Enter your passcode to confirm

This won’t delete personal data but will remove Wi-Fi passwords and VPNs.


7. Contact Your Carrier (or Apple Support)

If all else fails, contact your carrier to check for outages or account issues. If they confirm everything’s fine, Apple Support can help you inspect possible hardware or antenna faults.
