If you see No Service, Searching, or SOS on your iPhone or iPad

If you see SOS or "SOS only" in the status bar, your device isn't connected to a network, but you can still make emergency calls. This feature is available in Australia, Canada, and the United States.

Learn about using Emergency SOS on your iPhone.

To reconnect to your cellular network, follow these steps:

1. Go to Settings.
2. Turn on Airplane Mode for at least 15 seconds.
3. Turn off Airplane Mode.

Restart your device. If you're not sure how to do this, follow these steps to restart your iPhone or restart your iPad.

Issues with your carrier or account might affect your service. Contact your carrier to:

• Verify that your account is active and in good standing.
• Make sure that you're in an area with cellular network coverage and there are no outages in your area.
• Check that your device isn't blocked or barred from receiving cellular services and is set up with the right data plan.
• Ask if your local government requires IMEI registration to use an iPhone that you originally purchased outside your country or region.

Only your wireless carrier can access and manage details about your account:

• iPhone wireless carriers
• iPad wireless carriers

Update your iPhone or iPad to the latest version of iOS or iPadOS.

To manually check for and install a carrier settings update:

1. Make sure that your device is connected to Wi-Fi.
2. Tap Settings > General > About. If an update is available, you'll see an option to update your carrier settings.
3. To see the version of carrier settings on your device, tap Settings > General > About and look next to Carrier.

If you insert a new SIM card into your iPhone or iPad, you need to download the carrier settings for your new carrier.

If you have an iPhone with Dual SIM, follow these steps:

1. Go to Settings. 
2. Tap Cellular and tap the cellular line you'd like to review, then check to see if it's turned on. 
3. If the cellular line is off, turn it back on. Then check to see if you have service.

If you don't see your cellular line, contact your carrier to set up an eSIM or insert a physical SIM card. If you're using a physical SIM card, remove the SIM card and put it back in.

If your SIM card is damaged, doesn't fit in the SIM tray, or you transferred your physical SIM card from another device, ask your carrier for a new SIM card.

If you still see No Service after following these steps, contact your carrier.

iPhone and iPad devices that support 5G networks are not affected by the phasing out of 3G networks.

If your carrier confirms that there's no issue with your account or network, and a hardware issue is suspected, contact Apple Support.
