What Does SOS Only Mean on iPhone [12 Quick Fixes]

Sometimes, while using your iPhone, you might notice the usual signal bars change to "SOS" or "SOS Only", or find this term in the Control Center. Wondering what's going on?

Don't worry! In this guide, we'll explain why your iPhone is showing this message and what it signifies. Plus, we've got a bunch of 12 effective solutions for you to try and fix the "SOS Only" alert. Let's dive in and get that sorted!

What does SOS Only Mean on iPhone?

SOS Only on iPhone

Seeing "SOS Only" or simply "SOS" on your iPhone indicates that your phone isn't connected to a regular cellular network and cannot perform standard cellular functions. In this mode, you can only place emergency calls to numbers such as 911 (in the US), 112 (in Europe), 999 (in the UK), or 000 (in Australia).

Sadly, regular calls or text messages won't go through, and you can't use internet-based services either. Your phone is basically restricted to contacting emergency services like the police, fire department, ambulance, coastguard, or mountain rescue, depending on your location.

It's important to note that "SOS" and "SOS Only" differ from the "No Service" notification. While "SOS" allows you to make emergency calls, "No Service" signifies a complete lack of network coverage, preventing even emergency calls.

Why Does Your iPhone Display SOS / SOS Only?

  1. Cellular network/carrier issues: Your carrier's network might be experiencing outages or technical difficulties.

  2. SIM Card Problems: The SIM card might be damaged, improperly inserted, or deactivated.

  3. No Service Area: You might be in an area with poor or no cellular coverage.

  4. Software Glitches: Sometimes, software bugs or glitches can cause the phone to lose its connection to the cellular network.

  5. Hardware Issues: Your iPhone might have hardware problems affecting its ability to connect to the network.

  6. Airplane Mode: Your phone might be stuck in Airplane mode, which disables cellular connections.

  7. Restrictions: Certain service restrictions or carrier-related issues might be causing the problem.

  8. Roaming Issues: If you are in a different country or region, there might be roaming issues affecting the network connection.

Way 5: Check Data Roaming

Data roaming allows you to use different cellular networks, which can sometimes be costly.

Managing your data roaming settings is essential for maintaining a reliable network connection. Follow these steps to adjust your settings:

In Your Home Region: 

If you are not traveling, keeping data roaming off ensures that your phone maintains a consistent connection with familiar networks. 

  • Navigate to: Settings > Cellular > Data Roaming (toggle it off).

While Traveling Internationally:

If you are abroad, enabling data roaming can facilitate a steady network connection

  • Navigate to: Settings > Cellular > Cellular Data Options > Data Roaming (toggle it on).

Way 6: Switch to 4G or LTE

Given that 5G isn't fully available worldwide, it might be causing issues with your signal strength and connection. If you encounter the 'SOS Only' problem persistently, it might be prudent to switch off 5G on your iPhone and instead use 4G or LTE.

Way 7: Check Your SIM Card

Reinsert Your SIM Card:

  • Eject your SIM card.

  • Inspect it for any visible damages.

  • Reinsert it properly, ensuring a good connection.

Activate Your SIM:

  • Make sure your SIM card is actively registered with your carrier to avoid connection issues.

If you possess an iPhone model XR, XS, XS Max, or newer, you might find it beneficial to transition to an eSIM for potentially better connectivity.

Way 8: Update Carrier Settings

Carrier settings are provided by your network carrier to enhance cellular connectivity and overall phone performance. It's a good idea to check if an update is available, especially if you're experiencing 'SOS Only' issues.

Updates are generally automatic, but you can also manually check and update the carrier settings on your iPhone. Before you start, make sure your device is connected to stable Wi-Fi and Cellular Data is enabled.

Step 1: Go to Settings > General > About

Step 2: If an update is available, a notification will pop up. Tap 'Update' to begin the installation process.

If you have recently set up an eSIM or plan to do so, it might be necessary to manually download the new carrier settings.

  • Disable the 'Automatic selection' option.

  • Choose your network provider from the list available.
