Fix Android Emergency Calls Only: Step-by-Step Guide

Seeing “Emergency calls only” on your Android phone means the device has lost connection to your carrier’s network, so it can only reach emergency numbers. This guide walks you through the most common fixes, from quick toggles to SIM card checks and network resets, so you can get your signal back.

What You’ll Need

Your Android phone
Your SIM card (and the SIM ejector tool or a paperclip)
Access to your carrier’s settings (APN details, if you plan to manually configure them)
Wi-Fi connection (optional, for some fixes)

Step-by-Step

Toggle Airplane Mode On and Off. Swipe down from the top of the screen to open Quick Settings. Tap the Airplane Mode icon to turn it on, wait 10–15 seconds, then tap it again to turn it off. This forces your phone to re-scan for networks and often resolves temporary signal glitches.
Restart Your Phone. Press and hold the power button, then select “Restart” (or “Reboot”). If there’s no restart option, power off completely, wait 30 seconds, and power back on. This clears temporary software issues that can cause the phone to lose network registration.
Check the Network Mode Setting. Go to Settings > Network & Internet > Mobile network (or Connections > Mobile networks on Samsung). Tap “Network mode” and make sure it’s set to “Global” or “LTE/GSM/WCDMA” (auto). If it’s set to a specific band like “LTE only,” switch it to an automatic option and test the signal.
Manually Select Your Carrier. In the same Mobile network menu, tap “Network operators” or “Carrier selection.” Turn off “Select automatically,” wait for the list to populate, then tap your carrier’s name. If it connects, the issue was a failed automatic registration. If it fails, try another carrier from the list (like a roaming partner) and then switch back.
Remove and Reinsert the SIM Card. Power off the phone. Use the SIM ejector tool to pop out the SIM tray. Inspect the SIM for dirt or damage, wipe it gently with a dry cloth, and reinsert it firmly. Power the phone back on and check the status bar.
Clean the SIM Card and Tray. If the SIM looks dirty, use a soft, dry cloth or a pencil eraser to gently clean the gold contacts. Do not use water or cleaning solutions. Also check the tray itself for debris that might prevent proper contact.
Update Your Carrier Settings (APN). Go to Settings > Network & Internet > Mobile network > Access Point Names. If the APN is blank or incorrect, tap the “+” icon to add a new one. Enter your carrier’s APN settings (available on their website or support page). Common fields include “Name,” “APN,” “Username,” and “Password.” Save and select the new APN.
Reset Network Settings. Go to Settings > System > Reset options > Reset Wi-Fi, mobile & Bluetooth (on Samsung: Settings > General Management > Reset > Reset network settings). This clears saved Wi-Fi networks, Bluetooth pairings, and all mobile network settings, returning them to factory defaults. You’ll need to re-enter Wi-Fi passwords afterward.
Check for System Updates. Go to Settings > System > System update (or Software update). Install any pending updates, as they often include carrier-specific bug fixes that resolve network registration issues.
Test the SIM in Another Phone. If you have access to another unlocked phone, insert your SIM there. If it works, the problem is with your phone’s hardware or software. If it still shows “Emergency calls only,” the SIM card itself is likely faulty or deactivated.

Common Mistakes

Skipping the restart. Many users jump straight to complex settings changes, but a simple reboot fixes a surprising number of network issues.
Using the wrong APN. Typing an APN from an old carrier or a generic guide can cause more problems. Always use the exact APN provided by your current carrier for your specific plan.
Forgetting Wi-Fi calling is off. If Wi-Fi calling is enabled but your Wi-Fi is weak, the phone might prefer a broken cellular connection. Temporarily disable Wi-Fi calling to force the phone to use the mobile network.
Assuming the SIM is fine. SIM cards can fail or become damaged. If cleaning and reinserting doesn’t work, don’t rule out a dead SIM.
Resetting network settings without noting Wi-Fi passwords. This is a destructive step; you’ll have to reconnect to every saved Wi-Fi network. Write down critical passwords first.

Tips

Toggle 2G/3G manually. In some areas, LTE or 5G bands are congested or blocked. Temporarily switching to 3G or 2G (if your carrier still supports it) can get you a signal, confirming the issue is with a specific band.
Check for outage. Before doing anything, visit your carrier’s website or social media for outage reports. If there’s an outage in your area, no phone-side fix will work.
Update your PRL/Profile (Samsung/CDMA). On some carriers (especially CDMA-based ones like Verizon or Sprint legacy), go to Settings > Connections > Mobile networks > Carrier settings and tap “Update profile” or “Update PRL.” This refreshes your phone’s network configuration.
Use a different location. “Emergency calls only” might simply mean you’re in a dead zone. Walk outside or to a window and see if the signal returns.
Keep the SIM tray dry. Moisture on the SIM contacts is a common cause. If you’ve been near water, remove the SIM and let everything dry for a few hours.

Troubleshooting

If none of the steps worked:

Try Safe Mode. Restart your phone and hold the volume-down button when the logo appears (method varies by manufacturer). In Safe Mode, third-party apps are disabled. If the signal returns, an app is interfering. Uninstall recently installed apps, especially VPNs, network optimizers, or battery savers.
Check for a physical SIM issue. If the SIM is visibly bent, scratched, or the gold contacts are worn, request a replacement SIM from your carrier. Many carriers provide eSIMs that don’t require physical hardware.
Switch to eSIM. If your phone supports eSIM and your carrier offers it, converting your physical SIM to an eSIM can bypass hardware issues with the SIM slot.
Factory reset (last resort). Back up your data first. Go to Settings > System > Reset options > Erase all data (factory reset). This restores the phone to a clean state, eliminating any software corruption. If the problem persists after this, it’s almost certainly a hardware issue.
Contact your carrier. They can check if your account is active, if the SIM is registered correctly, and if there are any blocks on your line. They can also send a network refresh signal to your phone.
Visit a repair shop. If you’ve tried everything and the SIM works in another phone, the antenna or baseband chip in your phone may be damaged. A professional diagnosis is needed.

Frequently Asked Questions

Q: Why does my phone say “Emergency calls only” when I have full bars?
A: “Full bars” might refer to Wi-Fi signal or a weak cellular signal that isn’t strong enough to register with the network. Check the status bar icon: if it shows a phone icon with a slash or “E”, you’re not actually connected to cellular data.

Q: Will I still be able to call 911 in “Emergency calls only” mode?
A: Yes. The phone can still reach emergency numbers (like 911 in the US) through any available network, even if your carrier’s network is unavailable. This is a safety feature.

Q: Can a bad SIM card cause this issue?
A: Absolutely. A damaged, dirty, or deactivated SIM card is one of the most common causes. Try cleaning it, reinserting it, or testing it in another phone.

Q: Does airplane mode fix “Emergency calls only”?
A: Sometimes. Toggling airplane mode forces the phone to re-register with the network. It’s a quick first step, but if the underlying issue is a bad SIM or network outage, it won’t permanently fix it.

Q: How long does a network reset take?
A: The reset process itself takes about a minute. Afterward, the phone will restart and reconnect to the network, which can take another 1–2 minutes. You’ll need to re-enter Wi-Fi passwords.

Q: Is “Emergency calls only” the same as “No Service”?
A: Not exactly. “No Service” means the phone can’t find any network at all. “Emergency calls only” means it can see a network, but your SIM isn’t allowed to use it, which points more toward a SIM or account issue.
