Why Does My iPhone Say SOS Only?

Check Your Cellular Coverage

Move to an area with better reception: The most common reason for “SOS Only” is simply being in an area with poor or no cellular coverage. Try moving to a different location, ideally one with a clear view of the sky.
Check your carrier’s coverage map: Visit your carrier’s website to see if there are any reported outages or areas with limited coverage near you.

Restart Your iPhone

Power off your iPhone: Press and hold either volume button and the side button until the power-off slider appears.
Drag the slider to turn your device completely off.
Wait 30 seconds.
Press and hold the side button again until you see the Apple logo.

Update Your Carrier Settings

Connect to Wi-Fi: Ensure your iPhone is connected to a stable Wi-Fi network.
Go to Settings > General > About.
Wait for a prompt: If an update is available, you’ll see a pop-up message asking you to update your carrier settings. Follow the on-screen instructions.

Check Your SIM Card

Power off your iPhone.
Locate the SIM card tray: This is usually on the side of your iPhone.
Insert a SIM eject tool or a straightened paperclip into the small hole to release the tray.
Remove the SIM card.
Inspect the SIM card for any damage.
Reinsert the SIM card securely into the tray.
Power on your iPhone.

Reset Network Settings

Go to Settings > General > Transfer or Reset iPhone > Reset.
Tap Reset Network Settings.
Enter your passcode if prompted.
Confirm the reset. Note that this will erase saved Wi-Fi passwords, so you’ll need to re-enter them.

Update Your iOS

Connect to Wi-Fi: Ensure your iPhone is connected to a stable Wi-Fi network.
Go to Settings > General > Software Update.
Download and install any available updates.

Verify that the correct date and time are displayed.

Restore Your iPhone

Back up your iPhone: Use iCloud or your computer to create a backup of your data.
Connect your iPhone to your computer.
Open Finder (macOS) or iTunes (Windows).
Select your iPhone.
Click “Restore iPhone.”
Follow the on-screen instructions to restore your iPhone to its factory settings.
Restore from your backup after the process is complete.

Hardware Issues

Inspect your iPhone for physical damage.
Contact Apple Support or visit an authorized service provider for repair.

Airplane Mode

Open Control Center: Swipe down from the top-right corner of your screen (or swipe up from the bottom on older iPhones).
Tap the Airplane Mode icon to turn it off.

Roaming Settings

Go to Settings > Cellular > Cellular Data Options.
Ensure “Data Roaming” is enabled if you are traveling internationally.

Software Glitches
