"Emergency Calls Only" appears on your phone when it loses connection to your carrier's network but retains the ability to dial emergency services like 911/112. This indicates a network disruption rather than complete hardware failure.
Immediate Fixes for No Service Signal
Resolve network issues efficiently with these proven steps:
- Toggle Airplane Mode: Enable for 30 seconds, then disable to force network reconnection.
- Reboot Device: Power cycle phone to clear software glitches affecting signal reception.
- Check Carrier Settings: Update carrier settings via Settings > General > About if prompted.
- Manual Network Selection: Navigate to Settings > Cellular > Network Selection, disable "Automatic," choose your provider.
- Inspect SIM Card: Power off, remove SIM, clean contacts with microfiber cloth, reinsert firmly.
Advanced Troubleshooting
If basic steps fail:

- Reset Network Settings: Erase saved networks via Settings > General > Reset (preserves data).
- Test in Alternate Locations: Determine if issue is location-specific (building materials/interference).
- Verify Account Status: Contact carrier to confirm service payments and possible outages in your area.
When Hardware is Suspected
If problems persist:
- Try another SIM card to isolate device/carrier issues
- Examine for physical damage or moisture indicators
- Seek professional diagnostics for potential antenna/baseband failure
For persistent "Emergency Calls Only," combine software resets with carrier confirmation to restore service. Hardware faults require professional assessment.
