What “SOS Only” on iPhone Means, & How to Fix SOS Mode
Occasionally when using iPhone, you may see the cellular service status bars disappear and be replaced by “SOS” or “SOS Only”, or you may see “SOS Only” in Control Center.
What does SOS Only Mean on iPhone?
If you see the “SOS or “SOS Only” text in the iPhone status bar, this means the iPhone is not connected to a cellular network that is able to use typical cellular connectivity. However, SOS / SOS Only does imply that you can continue to make emergency calls from the iPhone.
You may see the SOS or SOS Only message on the iPhone when you’re out of a service area, in an area with poor cellular connectivity or coverage, in rural areas, tunnels, and in other situations where the iPhone is unable to connect to a cellular network.
SOS and SOS Only differs from ‘No Service’ in that SOS means you can still make emergency calls to 911 or the equivalent, but “No Service” means there is quite literally no service coverage available at all, not even for emergency.
