What is iPhone SOS Only Issue – How to Fix It?

If your iPhone is showing SOS or SOS only in the status bar, you are out of your network service provider’s coverage range. You can only make emergency calls. However, this useful feature can sometimes become troublesome if SOS and SOS only do not go away even if you are in the cellular network range. There can be different reasons for such a warning sticking to your iPhone’s status bar. In this guide, I will cover how to fix if you see SOS or SOS only on your network status bar.

Why is my iPhone Showing SOS only

While traveling if you leave the coverage area of your carrier then your iPhone automatically goes into SOS or SOS only mode. The SOS only appears in the place of your cellular network bar.

This means you can only make emergency calls to specific numbers such as 911 (USA/Canada), 999 (United Kingdom), 000 (Australia), and 112 (India). You won’t be able to make normal calls, send text messages, or use internet service.

Is SOS only on my iPhone an Issue

If your iPhone goes into SOS only state then it gets back into the normal state when you enter the carrier’s coverage area as it is a failsafe phenomenon. But it can become an issue if it does not go away automatically. So, what are the possible reasons that your iPhone carrier status is showing SOS only. Let’s find out.

What are the Reasons for SOS only Issue

If SOS only has stuck to your iPhone then there might be the following reasons:

The Carrier Service Outage

The carrier service may at times be interrupted due to maintenance or sometimes weak signals can also lead to the SOS only issue. In such a situation you need to wait for the carrier to fix the issue.

Poor Carrier Signals

The weak signal can also sometimes cause the SOS only. Normally gets corrected when you enter into an area with strong carrier signals.

Sim Card Issue

If you are using a damaged sim card then you may also get SOS only. Check your sim card and try to replace it with a different sim card.

Note: If you occasionally get SOS only warning then try to change the carrier.

Note: I am using a device with iOS 17 to perform the following steps.

1. Open Settings and tap on the Cellular option:

2. Disable the Cellular Data and enable it:

3. Enable Data Roaming

If you frequently travel abroad and leave the carrier coverage then you will also get SOS only status. But it can be avoided by enabling the Data Roaming on iPhone.

The steps to enable data roaming on iPhone are:

1. Open Settings, and tap on Cellular.

3. Enable Data Roaming:

The cellular service providers occasionally update the service to include new features. Whenever carrier settings update is available, you are prompted with Carrier Settings Updates, tap on Update to immediately update the settings.

You can also manually update the carrier setting by the following steps:

1. Go to Settings and tap on General.

2. Tap on About, you will get the prompt of carrier setting if available.

5. Turn On/Off the Airplane Mode

Turning Airplane mode on and then turning it back off will quickly reset the cellular network. It is the easiest way to reset the cellular network. This step can also solve the SOS only issue on your iPhone:

Open the Control Center, tap on the airplane icon to enable it, and then tap again to disable it.

Or go to the Settings and toggle On/Off the Airplane Mode.

6. Turn On/Off the Auto Network Selection

The network selection on the iPhone is completely automatic but many times turning off the Airplane glitch it. It can give you the No Service or SOS only error. To fix it see the following steps:

1. Open Settings, and tap on Cellular.

2. Tap on Network Selection, and toggle Automatic off/on it.

7. Remove and Re-insert the SIM

If you are using a physical SIM card on your iPhone then try to take it. Inspect it for any damage, if you find try to replace it. Also carefully examine the SIM card tray if it is bent or not.

Note: If you are using an eSIM then avoid resetting it.

8. Reset Network Settings

Additional Fixes to Fix SOS only Issue

Some other fixes to get rid of SOS only issue on iPhone.

Update iPhone

Operating system bugs can also cause this issue, ensure you keep your operating system up to date. To check for iOS updates, go to Settings > General > Software Update.

Reset iPhone

You can also go for your phone reset if SOS only issue remains. But I would not recommend going for this option, as doing this will erase your data. If you want to reset your iPhone backup your phone first. The easiest way to back up your iPhone is using the iCloud service.

Contact Apple Support

If the issue does not go away then try to contact Apple Support. The fastest way to access the Apple customer is by using the Apple Support app. Or directly visit Apple Support from here.

How SOS only and No Service are Different

If you see No Service or Searching, it signifies that the device is not connected to the carrier or searching for the carrier. But when it is SOS only, it means that you can make emergency calls but your carrier network is not available.

Note that when it is No Service then it means you do not have any network service around you cannot even make emergency calls.

How SOS Emergency Calls Work

The SOS message appears on your status bar when you are out of the coverage area of your cellular service provider but you can still make emergency calls. How do those emergency calls work?

When you go out of your carrier coverage range then you are still in the coverage range of other networks that allow you to make emergency calls. This service is only available in the United States, Canada, and Australia.

Conclusion

SOS only on iPhone means that you can only make emergency calls as you are out of your carrier network coverage area. This can be fixed by just entering into the coverage area of your network. But if you get SOS only on your status bar even if you are in the range of your carrier network then it is an issue. You can try various fixes as such turning on/off the cellular service, auto network selection, or Airplane mode. Or reset the network setting and remove and re-inserting the SIM.
