If you see SOS, No Service or Searching on your iPhone or iPad
If you see SOS or "SOS only" in the status bar, your device can still make emergency calls. If you see No Service or Searching in the status bar on your iPhone or iPad (Wi-Fi + Cellular), your device isn't connected to a mobile network.
On iPhone models running iOS 18, you can download the latest version of the Apple Support app to run additional diagnostics that may help determine the source of your device's issue.
If you see SOS or SOS only

Contact your network provider

Verify that your account is active and in good standing.
Make sure that you're in an area with mobile network coverage and there are no outages in your area.
Check that your device isn't blocked or barred from receiving mobile 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 network provider can access and manage details about your account:
Update your iPhone or iPad
Update your iPhone or iPad to the latest version of iOS or iPadOS.

Go to Settings > General > About. If an update is available, you'll see an option to update your network provider settings.
To see the version of network provider settings on your device, go to Settings > General > About and look next to Network Provider.
If you insert a new SIM card into your iPhone or iPad, you will need to download the network provider settings for your new network provider.
If you have an iPhone with Dual SIM
If you have an iPhone with Dual SIM, follow these steps:
Go to Settings.
Tap Mobile Data and tap the mobile line you’d like to review. Then check if it’s turned on.
If the mobile data line is off, turn it back on. Then check if you have any service.
If you don't see your mobile data line, contact your network provider 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've transferred your physical SIM card from another device, ask your network provider for a new SIM card.
