What Does SOS Mean on iPhone? And How to Fix It?

If you’ve ever glanced at your iPhone and noticed “SOS Only” in the top corner, you’re not alone. It can be confusing and even a little stressful, especially if you’re waiting on an important call or need to get online. I know how frustrating it is when your phone suddenly stops working as expected. So, what does “SOS Only” mean, and how can you fix it? I’m here to walk you through everything you need to know, with clear steps and real-world tips to help you get your iPhone back to normal.

What Does SOS Mean on iPhone?

When your iPhone displays “SOS Only” (or just “SOS”) in the top-right corner—right where you’d usually see your network bars and carrier name—it’s your phone’s way of letting you know it can’t connect to your regular cellular network. In this state, you’re only able to make emergency calls. Regular calls, text messages, and cellular data won’t work until you restore your connection. Don’t worry—I’ll show you precisely what to do next.

What emergency numbers can you call?

Depending on your region, your iPhone will allow you to call local emergency numbers such as:

1. 911 (United States/Canada)
2. 112 (Europe)
3. 999 (United Kingdom)
4. 000 (Australia)

If unsure, your iPhone will automatically dial the correct emergency number for your location.

Where does “SOS Only” appear?

You’ll see “SOS” or “SOS Only” in the status bar at the top of your screen, replacing your usual signal bars or carrier name.

“SOS Only” vs. Emergency SOS Mode: What’s the Difference?

It’s important not to confuse “SOS Only” with Emergency SOS mode:

• SOS Only is a network status—it shows up when your iPhone can’t connect to your carrier, but you can still make emergency calls.
• Emergency SOS mode is a feature you turn on (by pressing and holding the side and volume buttons) to quickly call for help if you’re in danger.

Quick Fixes for “SOS Only” on iPhone

Here’s a handy troubleshooting table:

Why Does My iPhone Say “SOS Only”? (Common Causes)

Some of the most common—and a few less obvious—reasons include:

1. Out of Network Coverage: You’re in an area with no signal from your carrier. However, your phone can still connect to other networks for emergency calls—for example, rural areas, tunnels, underground garages, or heavily shielded buildings.
2. Carrier Outage: Your carrier may be experiencing a temporary outage due to maintenance, weather, technical issues, or large-scale infrastructure failures.
   Example: During the AT&T outage in February 2024, millions saw “SOS Only” for over 12 hours.
3. Account or Billing Issues: Suppose your carrier account is suspended due to missed payments, fraud alerts, or verification problems. In that case, your phone may lose regular connectivity and display “SOS Only”—even if the network is otherwise available.
4. Airplane Mode Enabled: Airplane Mode turns off all wireless connections. If it’s on, you’ll see “SOS Only” (or “No Service”).
5. Roaming/Data Roaming Issues: When traveling internationally, if data roaming is off or not set up, your iPhone may show “SOS Only.” Some local carriers may not support your plan.
6. Faulty, Damaged, or Inactive SIM/eSIM: A damaged or incorrectly inserted SIM card, inactive SIM, or corrupted eSIM profile can cause network issues.
7. Carrier Profile or APN Misconfiguration: If your carrier settings or APN (Access Point Name) are outdated or corrupted—often after switching carriers or updating iOS—your phone may fail to connect properly.
8. iOS Bugs or Outdated Software: Software glitches or using an outdated iOS version can sometimes disrupt your network connection. Always keep your iPhone updated to the latest iOS for the best performance.
9. Hardware Malfunction: Physical damage to your iPhone (such as a broken antenna, water damage, or a faulty SIM slot) can prevent it from connecting to networks.
10. 5G Instability: In some areas, 5G coverage is unreliable. If your phone is set to use 5G but the signal is weak, you may see “SOS Only.”
11. Device Blacklisting or Regulatory Restrictions: If your device’s IMEI is blacklisted (e.g., reported lost or stolen), or if there are temporary government-mandated network shutdowns, your iPhone may be restricted to emergency calls only.
