How do I get my iPhone 8 out of SOS mode?

Hello!

SOS Only means you don’t have a cellular connection, but you’ll still be able to call emergency services using other carriers’ towers. You might want to reach out to your carrier if it’s an issue for you.

👉 If you see SOS, No Service, or Searching on your iPhone or iPad - Apple Support

Have a great day!

SOS means you currently have no cellular connection to your carrier. This either means you are in an off-the-grid spot with no connection, or there is an issue which your carrier needs to fix.
