Why Is My Phone on SOS and How Do I Fix It?

If your phone is on SOS, it means your phone cannot connect to your own carrier's network right now. It can still call 911 by borrowing another carrier's network. Regular calls, texts and data will not work until it reconnects.

Most of the time this is short and fixable. A weak signal, a carrier outage, a SIM card that came loose or an account problem causes almost every case. Work through the steps below in order, and check the top of your screen after each one.

The Short Answer

What it means. No connection to your carrier, but emergency calls still work.
Most common cause. Weak signal where you are standing, or an outage.
First fixes. Airplane Mode on and off, then a restart.
Next checks. Your SIM or eSIM line, updates and roaming.
If it will not clear. Call your carrier. The problem is often your account, not your phone.

What SOS on Your Phone Actually Means

On an iPhone, SOS or SOS only shows up where your signal bars usually sit. Apple says it means your phone is not connected to your cellular network, but it can still place emergency calls through other carrier networks. Apple lists this label for Australia, Canada and the United States.

Android phones say the same thing in other words. Samsung phones show Emergency calls only. Samsung says this means the phone cannot connect to your carrier's network. Other Android phones may show "No service" or "Emergency calls only" in the status bar or the notification shade.

So SOS is not a mode you turned on by mistake. It is a status. Your phone is telling you it lost your network and that 911 still works.

SOS, No Service and the Satellite Icon Are Three Different Things

People mix these up a lot, and the fix depends on which one you see.

SOS or SOS only. No connection to your carrier. Emergency calls still go through on another network.
No Service or Searching. No connection to any cellular network at all. Apple shows these when your phone cannot find a network.
A satellite icon or a satellite prompt. This is a separate feature. Apple's Emergency SOS via satellite works on iPhone 14 and later when there is no cell or Wi-Fi coverage at all. Apple says it is free for two years after you activate the phone. Google offers Satellite SOS on Pixel phones since Pixel 9, except the Pixel 9a.

If you only see SOS, you do not need a satellite. You need your carrier's network back.

Why Your Phone Says SOS

These are the usual causes, from most likely to least likely.

Weak signal where you are. Basements, elevators, thick walls, rural roads and canyons. Samsung says signal problems are behind most of these messages.
A carrier outage. Your carrier's network is down in your area.
A SIM or eSIM problem. The SIM is loose or damaged, the eSIM was never activated, or your line is switched off.
An account problem. A missed bill, a paused line or a plan change can cut service.
A blocked phone. Apple says to ask your carrier to make sure the phone is not blocked or barred from service.
Roaming is off when you travel. Out of the country, your phone may need data roaming turned on.
Old software. An old system or carrier settings file can cause trouble on newer networks.
A hardware fault. Rare, and usually after a drop or water damage.

How to Fix SOS on iPhone

Try each step, then check the top of your screen before moving on. These steps follow Apple's own support page.

Toggle Airplane Mode for 15 Seconds

Open Settings and turn on Airplane Mode. Apple says to leave it on for at least 15 seconds, then turn it off. This forces the phone to look for your network again.

Restart Your iPhone

Turn the phone off, wait a moment, and turn it back on. A restart clears most short glitches.

Check Your SIM or eSIM Line

Open Settings, then Cellular, then tap your line. If it says the line is off, tap Turn On This Line. If you have a physical SIM card, take it out with the tray tool and put it back in. Apple says to ask your carrier for a new SIM if yours is damaged, does not fit the tray, or came from another phone.

Install Updates

Open Settings, then General, then Software Update, and install anything waiting. Then check for a carrier settings update. Connect to Wi-Fi, open Settings, then General, then About. If an update is ready, you will see a prompt to install it.

Turn On Data Roaming When You Travel

Out of the country, open Settings, then Cellular, then Cellular Data Options, and turn on Data Roaming. Check your plan first, since roaming can cost extra.

Reset Network Settings

If nothing above helped, open Settings, then General, then Transfer or Reset iPhone, then Reset, then Reset Network Settings. This does not delete photos or apps. Telstra's guide warns that it does delete saved Wi-Fi networks, Bluetooth pairings and their passwords, so have your Wi-Fi password handy.

How to Fix SOS or Emergency Calls Only on Android

Menu names vary by brand, but the steps are the same idea.

Airplane Mode. Swipe down from the top of the screen, turn on Airplane Mode, wait 15 seconds, and turn it off.
Restart. Hold the power button and choose Restart.
Check the SIM. Samsung says an eSIM that was never activated, a missing SIM, or a SIM with a problem can all cause Emergency calls only. Reseat a physical SIM and check that your line is on under the SIM settings.
Leave the emergency screen. On a Samsung phone, if you are stuck on the emergency call screen, tap Back. Samsung says older phones running software before One UI 5.1 had an Emergency mode you can turn off from the three dot menu in the top right corner.
Update. Open Settings and look for Software update or System update.
Reset network settings. Many Android phones have a Reset network settings option. Type "reset" into the search bar at the top of Settings to find it.

When It Is Your Carrier, Not Your Phone

If SOS shows up in a place where you always have bars, and the steps above do not fix it, the problem is very often on the carrier side. Apple's list of things to ask your carrier is a good script.

Is my account active and in good standing?
Is there an outage or a coverage gap where I am?
Is my phone blocked or barred from service?
Is my plan set up right for data?

You can call from another phone, use your carrier's app over Wi-Fi, or chat with them online. If they confirm the account and network are fine and the phone still shows SOS, Apple says you may need service for a hardware problem.

One more warning. If your service vanishes for no reason and does not come back, ask your carrier about a SIM swap. That is when a criminal talks your carrier into moving your number to their SIM. Our guide on how to tell if your phone is hacked explains what to do next.

How to Stay Reachable While You Are on SOS

You can still talk and text in a lot of places without cell service.

Turn on Wi-Fi Calling. On iPhone, open Settings, then Cellular, then Wi-Fi Calling, and turn on Wi-Fi Calling on This iPhone. Apple says that if cellular service is not available, emergency calls might also go over Wi-Fi Calling. Your carrier has to support it. If home Wi-Fi is the weak link, our guide to fix slow home Wi-Fi helps.
Use messaging apps on Wi-Fi. iMessage, WhatsApp and similar apps work over any Wi-Fi network.
Know your satellite option. On iPhone 14 or later, or a Pixel 9 or later except the 9a, you can text emergency services by satellite when there is no cell or Wi-Fi at all. You need to be outside with a clear view of the sky.

When It Is Time for a New Phone

If your phone shows SOS everywhere, even right after your carrier says your line is fine, and a new SIM does not help, the radio inside the phone may be failing. That is worth a repair quote. If the phone is old, our guide on when to replace your phone can help you decide whether to fix it or move on.

The Bottom Line

SOS means your phone lost your carrier but can still call 911. Toggle Airplane Mode for 15 seconds, restart, check your SIM or eSIM line, and install updates. If you travel, turn on roaming. If it still will not clear in a place where you usually get bars, call your carrier and ask about your account, outages and whether the phone is blocked.

Questions Readers Ask

Why is my phone on SOS?

Your phone cannot connect to your own carrier's network, but it can still reach emergency services through another carrier's network. Weak signal, a carrier outage, a SIM or eSIM problem, or an account problem are the usual causes.

Why does my phone say SOS only?

SOS and SOS only mean the same thing. Apple says the label shows when your phone is not connected to your cellular network but can still make emergency calls through other carrier networks. Apple lists this for Australia, Canada and the United States.

Can I still call 911 when my phone says SOS?

Yes. That is the whole point of the label. Your phone borrows any network it can find for an emergency call. Normal calls, texts and data will not work until your own network comes back.

How do I get my phone out of SOS mode?

Toggle Airplane Mode for at least 15 seconds, restart the phone, check that your SIM or eSIM line is on, and install updates. If it stays on SOS in a place where you normally get service, call your carrier.

Is SOS the same as Emergency SOS via satellite?

No. The SOS label means no cell service but emergency calls still work. Emergency SOS via satellite is a separate feature on iPhone 14 and later, and Pixel phones since Pixel 9 have a similar one. It lets you text emergency services when there is no cell or Wi-Fi coverage at all.

Why does my phone keep going to SOS at home?

If it happens in one spot, it is usually weak signal in that spot. Turn on Wi-Fi Calling so calls and texts can go over your home Wi-Fi. If it happens everywhere, the cause is more likely your SIM, your account or the phone itself.

Does SOS mean my phone was hacked?

Usually not. But if your service drops for no clear reason and does not come back, call your carrier from another phone. A SIM swap, where a criminal moves your number to their own SIM, can look like this.
