If your iPhone suddenly displays “SOS” or “SOS Only” in the status bar, and you’re unable to make regular calls, send texts, or use mobile data, don’t panic—you’re not alone. It’s a surprisingly common issue that many iPhone users face. The good news? It’s usually a simple problem with a straightforward fix.
In this article, we’ll walk you through everything you need to know about SOS mode on iPhone, why it happens, and step-by-step solutions to get your phone back to full service. Whether it’s caused by a signal problem, SIM card issue, or a system glitch, we’ve got you covered.
What Does “SOS” or “SOS Only” Mean on iPhone?
When your iPhone displays “SOS” or “SOS Only”, it means:
- The device cannot connect to your cellular carrier’s network.
- You can only make emergency calls, like 112, 911, or other regional emergency services.
- Regular phone functions such as calls, SMS, and mobile data are unavailable.
This feature exists so that even if your phone has no service from your provider, it will still try to connect to any available network to make an emergency call. It’s a safety net built into iOS.
However, if your iPhone stays stuck in SOS mode and you’re not in an emergency, that’s when it becomes a frustrating problem. Let’s get into how to fix it.
Common Causes of SOS Mode on iPhone
Understanding why SOS mode occurs helps you apply the right solution. Here are the most frequent triggers:
- Poor or no network coverage in your area
- SIM card issues, such as being improperly inserted or damaged
- Outdated carrier settings
- Pending software updates or a recent iOS glitch
- Billing or account-related problems with your mobile provider
- eSIM setup failure
- Incorrect network settings on your device
Now that you know what might be causing the issue, let’s dive into the actual fixes.
How to Get iPhone Out of SOS Mode – Step-by-Step Fixes
1. Check for Signal in a New Location
Sometimes the problem is as simple as being in a low-signal zone. Certain places like underground parking lots, elevators, or remote areas may not have proper network coverage.
Try this:
- Move to a more open space
- Get closer to a window
- Step outside if you’re indoors
- Wait a moment to see if signal bars reappear
If the SOS mode disappears once you’re in a new area, it’s just a signal issue.
2. Toggle Airplane Mode On and Off
Airplane mode disables and then refreshes your device’s network connections. A simple on-off toggle can fix temporary network hiccups.
Steps:
- Open Control Center (swipe down from top-right on Face ID models or swipe up from bottom on Touch ID models)
- Tap the Airplane icon
- Wait 10 seconds
- Tap it again to disable airplane mode
Give your phone a few seconds to reconnect to your carrier. Often, this alone will bring you out of SOS mode.
3. Restart Your iPhone
If toggling Airplane mode doesn’t help, a good old-fashioned restart might.
Steps:
- Press and hold the power button and volume up/down button together
- When the slider appears, swipe to power off
- Wait 30 seconds
- Press and hold the power button to turn it back on
Restarting clears out minor software bugs that could be interfering with your network connection.
4. Check SIM Card Status
Your iPhone’s SIM card is what connects it to your mobile network. If it’s loose, damaged, or not recognized properly, your device may default to SOS mode.
To check your SIM card:
- Turn off your iPhone
- Use a SIM ejector tool or paperclip to remove the SIM tray
- Remove and inspect the SIM card
- Wipe it gently with a clean, dry cloth
- Reinsert the SIM securely
- Turn your iPhone back on
If the issue was due to a poor connection, your phone should now reconnect to the carrier.
5. Update Carrier Settings
Your carrier may occasionally release updates that optimize connectivity. If you haven’t installed these, your iPhone might struggle to maintain a network connection.
To check for carrier settings updates:
- Go to Settings > General > About
- If a pop-up appears saying “Carrier Settings Update,” tap Update
If no prompt appears, your carrier settings are already up to date.
6. Install iOS Software Updates
iOS updates often include bug fixes, security patches, and performance improvements—sometimes specifically related to network connectivity.
Steps:
- Go to Settings > General > Software Update
- If an update is available, tap Download and Install
- Follow the prompts and wait for the update to complete
After updating, your device will reboot—and with it, your carrier connection may be restored.
7. Reset Network Settings
If none of the above work, resetting your iPhone’s network settings might fix misconfigured settings.
Warning: This will erase all saved Wi-Fi passwords and VPN configurations, but your data won’t be deleted.
Steps:
- Go to Settings > General > Transfer or Reset iPhone
- Tap Reset > Reset Network Settings
- Enter your passcode and confirm
Your phone will restart and attempt to reconnect to the mobile network from scratch.
8. Check for Carrier Account Issues
Sometimes the problem isn’t your phone—it’s your account. If you’ve:
- Missed a payment
- Changed plans
- Suspended service
- Ported your number
- Requested a SIM deactivation
…your phone may be stuck in SOS mode as a result.
What to do:
- Contact your mobile provider
- Ask if your account is active and in good standing
- Confirm your SIM or eSIM is properly activated
- Request any reactivation if needed
Once your account is verified, the SOS mode should disappear.
9. Try Another SIM Card
To rule out a SIM card issue, borrow a working SIM from someone else (same carrier, ideally) and try it in your phone.
If your iPhone connects to the network with the other SIM, your original SIM may be damaged or deactivated. You may need to get a replacement from your carrier.
10. Switch to or Reconfigure eSIM (if applicable)
If you’re using an eSIM and facing SOS issues:
- Go to Settings > Cellular
- Tap your eSIM plan
- Toggle Turn On This Line off and on again
- If needed, delete and re-add the eSIM through your carrier
Make sure the eSIM QR code or activation details are correct.
Bonus Fix: Enable and Disable Automatic Network Selection
By default, your iPhone will automatically choose the best network. But you can try toggling this feature to prompt a fresh network scan.
Steps:
- Go to Settings > Cellular > Network Selection
- Turn Automatic off
- Wait for networks to load
- Select your carrier manually
- Then toggle Automatic back on
This can help in areas with overlapping signals or if your phone failed to connect properly the first time.
What If SOS Mode Still Won’t Go Away?
If you’ve tried all the above and your iPhone is still stuck in SOS mode, it may be a deeper hardware issue or a serious SIM activation problem. At this point, consider:
- Contacting Apple Support
- Visiting an authorized Apple Service Center
- Calling your mobile provider’s support team
It’s possible that the antenna, SIM reader, or another internal component needs to be serviced.
How to Avoid Getting Stuck in SOS Mode Again
To prevent SOS mode from happening repeatedly, here are a few smart practices:
✅ Keep iOS and carrier settings updated
Install all recommended updates as soon as they’re available.
✅ Handle your SIM card carefully
Don’t swap SIMs too frequently, and keep the SIM tray free of dust or damage.
✅ Monitor your account status
Check for pending bills, usage limits, or account suspensions.
✅ Avoid unstable areas
Use Wi-Fi in places with weak cellular signals (like subways or rural zones).
✅ Turn off automatic switching between SIMs (if dual SIM is active)
This can prevent conflicting signals.
