Phone says emergency calls only: why it happens and how to fix it

You pick up your phone and the status bar has changed. Where the carrier name and the bars used to be, there are three words: Emergency calls only. You cannot make regular calls, send texts or use mobile data. The message looks serious, but it has a simple meaning. Your phone can see a tower, and the tower can see your phone, but your carrier is not letting your line onto the network. The reasons range from a weak signal in your building to an unpaid bill, and most can be sorted in a few minutes. Here is how to tell which one you have and the fixes to try, in the order that works most often.

What does emergency calls only mean?

Phones are built so that anyone can reach 911, even without a working plan. To do that, the phone is allowed to connect to any available network for an emergency call. When your own carrier does not accept your line, the phone drops back to that emergency-only state and tells you so. On an Android phone, you see Emergency calls only. On an iPhone, the same state is shown as SOS or SOS only in the status bar. The message is a symptom, not a cause, which is why the fix depends on why your line was refused.

Why does your phone say emergency calls only?

• Weak or no signal: in a basement, a rural area, an elevator or a building with thick walls, your carrier may be out of reach while another network is not.
• A carrier outage: a tower or a regional network problem can drop many phones at once.
• A SIM card problem: a loose, dirty, damaged or wrong SIM can not log in.
• Airplane Mode or a stuck radio: the modem may be in a bad state after a software hiccup.
• An account issue: a past-due bill, a suspended line, a number port in progress or a SIM swap can all cut service.
• A network setting: manual network selection, a wrong network mode or a corrupted carrier profile.
• A software bug: common right after an update.
• Hardware: a damaged antenna or SIM reader is rare, but it happens after a drop or water damage.

Fix 1: Is it just your location?

Before you change anything, move. Go outside, near a window, or to a higher floor. Look at other phones around you. If a friend on the same carrier shows bars and you do not, the problem is your phone or your line. If their phone is also down, it is likely an outage, and the fix is to wait. Your carrier's app, its social accounts and Downdetector-style sites often show outage reports, which you can check from Wi-Fi.

Fix 2: Turn Airplane Mode on and off

This forces the modem to look for the network again. Swipe to the quick settings, turn on Airplane Mode, wait for 30 seconds, and turn it off. On an iPhone, swipe down from the top right corner. On an Android phone, swipe down from the top of the screen. Watch the status bar for the carrier name and the bars to come back.

Fix 3: Restart the phone

A restart clears the glitches that Airplane Mode does not. Hold the power or side button, choose Restart or Power off, wait a moment, and turn the phone on again. If the phone says SIM PIN or asks for a code on start-up, enter it. If you do not know it, read our guide on a SIM that is locked and asks for a PIN.

Fix 4: Check Wi-Fi calling as a stopgap

If you are somewhere with Wi-Fi but no cell signal, Wi-Fi calling may let you call and text while you fix the rest. It only works if the line is active and the feature is turned on, so it will not fix an account problem. See how to turn on Wi-Fi calling on iPhone, or what Wi-Fi calling is if you are new to it.

Fix 5: Reseat the SIM card

A SIM that has shifted slightly can lose its connection. Turn the phone off, use the ejector tool to open the tray, take out the SIM and look at the gold contacts. If they look dirty, wipe them gently with a dry, soft cloth. Put the SIM back in the same direction, close the tray and turn the phone on. Our guides on removing a SIM card and cleaning a SIM card show the steps. If your phone uses an eSIM, there is no tray, so skip to the settings fixes.

Fix 6: Update the carrier settings and the software

Carriers send small updates that tell your phone how to connect. On an iPhone, connect to Wi-Fi or mobile data if you can, open Settings, tap General, tap About and wait a moment. If an update is available, a prompt appears. Then check Settings, General, Software Update. On an Android phone, open Settings, then Software update, and install what is offered. A pending update may be the reason the phone cannot register.

Fix 7: Reset the network settings

This clears saved Wi-Fi networks, Bluetooth pairings and cellular settings, so write down Wi-Fi passwords first. It is a common fix for a phone that cannot register.

Menu names change by phone and software version, so if you do not see these, search Settings for reset. On Android, you can also check the mobile network list. Open the network operator settings, switch from manual to automatic selection, and let the phone search again.

Fix 8: Check the account and test the SIM in another phone

If the steps above did not help, the problem may be on the account. Sign in to your carrier's app or website from Wi-Fi and look for a notice. A past-due bill, a suspended line, a number port that has not finished, a SIM swap or a plan that ended can all produce this message. Check that your payment went through, and that the line shows as active. Then test the SIM. Put it in a second phone that works with your carrier. If it also shows emergency calls only, the SIM or the account is the cause. If it works, the problem is your phone. You can also try a working SIM in your phone to learn the same thing from the other side.

If the phone was bought used, or unlocked from another carrier, check that the phone is compatible and not blocked. Our guide on how to check whether a phone works with your carrier helps. A phone reported lost or unpaid may be blocked by its IMEI, which also causes this message.

What should you say when you call the carrier?

Use another phone, or your carrier's chat, if you have Wi-Fi. Say that your phone shows emergency calls only, and that you have restarted it, toggled Airplane Mode, reseated the SIM and reset network settings. Ask these things in order:

• Is the line active, and is there anything on the account that blocks service?
• Is there an outage in my area?
• Is my SIM or eSIM valid? Can you send a new SIM or a new eSIM code?
• Is my phone's IMEI clean, and is it supported on your network?

Having the IMEI ready speeds this up. Our guide on how to find your IMEI number shows where to look. If the carrier keeps blaming the phone, and the phone is out of warranty, a repair shop can check the SIM reader and the antenna. If you are tired of the problems, switching carriers may be the better answer.

Can you still call 911?

Usually, yes. This is the whole reason the message exists. A phone can generally place a 911 call through any available network, even without service from your own carrier. Coverage still matters, so if you are in a place with no towers, the call can not go through. Do not rely on a phone that is in this state if you can get to a working one. If you are in danger and the call fails, try moving to open ground or a higher spot and try again.

When is it a hardware problem?

Think about hardware if the message started after a drop, after water damage or after a repair, and if a second SIM does not work in your phone either, while your SIM works in other phones. The antenna, the modem or the SIM reader may be damaged. That is a job for the maker or a repair shop. It is worth comparing the cost to the value of the phone, using our guides on repair costs and trade-in value before you spend.
