How to Get Rid of SOS Only on iPhone is straightforward once you use the current iPhone controls. The exact wording can vary slightly by iOS version, carrier, and iPhone model.
- Move to an area where your carrier normally has coverage and wait briefly for the iPhone to reconnect.
- Turn Airplane Mode on for about 15 seconds, then turn it off.
- Restart the iPhone.
- Open Settings > General > About and install a carrier settings update if one is offered.
- Check for an iOS update and contact your carrier if the line still cannot connect.
“SOS” or “SOS only” means your normal cellular network is unavailable, although emergency calling may still be possible. An outage, account issue, SIM/eSIM problem, or coverage problem can cause it.
