Your phone is on SOS because it lost normal cellular service. On iPhone, SOS or SOS only means the phone is not connected to your cellular network, while emergency calling through other carrier networks remains available in the United States, Canada, and Australia.
Start with a fresh cellular connection, then check the SIM or eSIM, carrier account, updates, and network settings.
Refresh the cellular connection first
Use this when the SOS message appeared suddenly, especially after weak coverage, a basement, an elevator, or travel between coverage areas. A quick reconnect clears a temporary cellular registration problem.
On iPhone, open Settings, turn on Airplane Mode for at least 15 seconds, then turn it off.
On Google Pixel, open Settings, go to Network and Internet, tap aeroplane mode, turn it on, wait 10 seconds, then turn it off.
On Samsung Galaxy, open Settings, go to Connections, and turn off Airplane mode when it is already on. To force a reconnect, turn Airplane mode on, wait 10 seconds, then turn it off. Move to stronger signal, then test calls again.
Restart the phone cleanly
A restart clears temporary modem and network registration problems without changing your data.
- 1.On iPhone X, 11, 12, 13, or later, press and hold either volume button and the side button until the power-off slider appears.
- 2.On iPhone 6, 7, 8, or SE 2nd or 3rd generation, press and hold the side button until the power-off slider appears.
- 3.On iPhone SE 1st generation, iPhone 5, or earlier, press and hold the top button until the power-off slider appears.
- 4.Drag the power-off slider, wait 30 seconds, then hold the side button or top button until the Apple logo appears.
- 5.On Samsung Galaxy, open the Power menu, tap Restart, then tap Restart again. On models without a dedicated Power button, swipe down with two fingers, tap the Power icon in Quick settings, then tap Restart twice.
Check your SIM or eSIM line
Phones show SOS, Emergency calls only, or No service when the active SIM or eSIM is missing, turned off, damaged, or not activated. Check this right after switching phones, transferring a number, changing carriers, or setting up a new eSIM.
On iPhone with Dual SIM or Dual eSIM, open Settings, tap Cellular, choose the cellular line, and tap Turn On This Line when the line is off.
When the cellular line is missing, contact your carrier to set up an eSIM or insert a physical SIM. For a physical SIM, remove the SIM, put it back in the tray, and ask your carrier for a replacement when the SIM is damaged, does not fit the tray, or came from another device.
On Pixel phones that support eSIM transfer, open Settings, go to Network & internet, tap SIMs, choose Add SIM, then use Transfer SIM from another device. Automatic transfer requires both devices on Android 12 or later, current Google Play Services, a screen lock, and carrier support.
On Samsung Galaxy, turn off the device, insert the ejector tool into the small hole next to the SIM tray, remove the tray, inspect the SIM, and reinstall it when there is no damage. Ask your carrier for a replacement SIM or eSIM activation when the problem continues.
If this fails, contact the carrier next because only the carrier can confirm activation, account status, and device provisioning.
Rule out a carrier or account problem
Use this when SOS stays after a restart, when the problem started after a SIM swap or eSIM transfer, or when more than one phone on the same carrier is affected. At that point, the line, account, plan, outage status, or device registration is the thing to check.
Contact your wireless carrier and ask them to verify that your account is active and in good standing. Have them check local outage status, plan compatibility, SIM or eSIM activation, device lock status, and IMEI or device provisioning.
Ask the carrier whether the device is blocked or barred and whether the correct data plan is attached to the line. For international travel, confirm that your plan supports roaming before changing roaming settings.
Install phone and carrier updates
Updates include cellular fixes, carrier setting changes, and modem-related improvements.
- 1.On iPhone, connect to Wi-Fi and power, then open Settings, General, Software Update, and tap Download and Install.
- 2.To check iPhone carrier settings, connect to Wi-Fi or cellular, then open Settings, General, About, and follow the prompt when a carrier update appears.
- 3.On Pixel, open Settings, System, then System update.
- 4.On Samsung Galaxy, open Settings, then Software update or System updates, and choose Download and install or Check for software updates.
Reset mobile or network settings
Use this after the basic refresh, restart, SIM, and carrier checks fail. A mobile or network reset rebuilds cellular registration and preferred-network settings. On iPhone, Reset Network Settings also clears Wi-Fi, VPN, and APN settings. On Pixel and Samsung Galaxy, Reset mobile network settings covers mobile settings only, and Galaxy keeps a separate Reset Wi-Fi and Bluetooth settings option.
On iPhone, open Settings, go to General, tap Transfer or Reset iPhone, choose Reset, then tap Reset Network Settings. This removes saved Wi-Fi passwords, preferred networks, and VPN or APN settings not installed by a profile or device management.
On Pixel, open Settings, tap System, choose Reset options, then tap Reset mobile network settings.
On Samsung Galaxy, open Settings, go to General management, tap Reset, choose Reset mobile network settings, tap Reset settings, enter your security credentials when prompted, then tap Reset.
Adjust roaming and network choices
Use this when SOS starts outside your home carrier coverage area. On iPhone with one SIM or eSIM, open Settings, tap Cellular or Cellular Data, turn on Cellular Data, open Cellular Data Options, and turn on Data Roaming.
On iPhone with Dual SIM or Dual eSIM, open Settings, tap Cellular or Cellular Data, turn on Cellular Data, tap the number you want to modify, open Cellular Data Options, and turn on Data Roaming.
On Pixel, open Settings, go to Network and Internet, tap SIMs, then review Mobile data, Roaming, Preferred network type, Network, and Access point names. For multiple SIMs, use the tabs at the top of Mobile network settings, and choose the right default under Your primary SIMs for Calls, Texts, and Mobile data.
Check for apps or managed device restrictions
Security, VPN, calling, launcher, and recently downloaded apps interfere with connectivity on Samsung Galaxy and Pixel phones. Samsung uses Safe mode to test downloaded apps; Google uses Safe Mode testing, app updates, removing recent apps, and factory reset after other troubleshooting fails.
On Pixel, update apps from Google Play Store, Profile icon, Manage apps & device, then Update all. Test Safe Mode, and when service returns there, remove recently added apps.
On Samsung Galaxy, open the Power menu, touch and hold Power off until Safe mode appears, then tap Safe mode. If service returns in Safe mode, open the App drawer, touch and hold the recent app, tap Uninstall, tap OK, then restart normally.
For work or school phones, locked cellular, APN, VPN, or cellular plan settings are controlled by the organization. On iPhone, check Settings, General, VPN & Device Management; remove a user-removable profile with Remove Profile, or contact the administrator when management cannot be removed.
If this fails, use the support or repair options below instead of changing random cellular settings.
Escalate when SOS still will not go away
On iPhone running iOS 18 or later, install or open Apple Support, select the affected iPhone, and follow the guided diagnostics for the cellular or SOS issue. When an iPhone or iPad shows Cellular Issue Detected after an update or restart, back it up, connect it to a Mac or Windows PC, select the device, open General in Finder or Apple Devices or Summary in iTunes, then Command-click Check for Update on Mac or Control-click Check for Update on Windows to reinstall the current software.
On Pixel 10, Pixel 10 Pro, Pixel 10 Pro XL, and Pixel 10 Pro Fold, open Settings, Device health & support, Tips & support, Contact us, enter the issue details, tap Next step, then choose Chat or Get a call. On Pixel 9a and earlier, open Settings, Tips & support, then Contact us.
On Samsung Galaxy, request service when the SIM is active and verified but the phone still shows Emergency calls only. Contact the carrier when network service problems remain after a reset.
Do not use an iPhone Emergency SOS toggle as a fix for SOS-only cellular status. Samsung’s old Emergency mode toggle applies only to software before One UI 5.1; on One UI 5.1 and later, use the cellular, carrier, reset, and service steps above.
Frequently Asked Questions
Why is my phone on SOS after switching carriers?
The SIM or eSIM activation, device lock, account status, number transfer, or IMEI provisioning needs a carrier check. Ask the carrier to verify the line, plan, outage status, and device registration.
Why does my Samsung say Emergency calls only?
Samsung says Emergency calls only appears when there is no active SIM or eSIM inserted or the SIM is damaged. Reinsert the SIM, test another active SIM from the same carrier when available, then request a replacement SIM or eSIM activation.
Will resetting network settings erase my phone?
No. On iPhone, Reset Network Settings removes saved Wi-Fi passwords, preferred networks, and VPN or APN settings not installed by a profile or device management.
Should I turn off Emergency SOS to remove SOS on iPhone?
No. iPhone SOS in the status bar is a cellular service state, not the Emergency SOS safety feature. Use cellular reconnect, SIM or eSIM, carrier, update, reset, and Apple Support diagnostics instead.
