What Does SOS Only Mean on iPhone

“SOS Only” on an iPhone means the device is unable to connect to your regular cellular network but can still make emergency calls. This typically happens when your iPhone cannot find your carrier’s signal but can connect to any available network for emergency services. It might appear in areas with poor signal coverage or if there’s an issue with your SIM card or carrier settings. Turning on airplane mode, restarting the phone, or updating carrier settings can sometimes resolve this.
