If your iPhone has switched to “SOS Only” mode, you won’t be able to make phone calls or send SMS Text Messages. You can find below the step to fix this problem on iPhone.
What is “SOS Only” on iPhone?
When iPhone comes up with “SOS Only” badge at top-left corner of the screen, it means that your iPhone can only make calls to energency phone numbers like 911 (US) or 999 (UK).

SOS Mode on mobile devices is only available in United States, Canada and few other Countries. If SOS Mode is not available, your iPhone may come up with No Service or Searching error message.
Why Does iPhone Switch to “SOS” Mode?
In general, an iPhone goes into “SOS” mode, whenever it loses contact with the Carriers network and ends up losing its internet connection.
This usually happens when you move to a new location that is outside the coverage area of your Service Provider’s network.
Apart from this, iPhone can get stuck in SOS mode due to the SIM Card not being inserted properly, SIM Card becoming damaged/corrupted and other reasons.
When iPhone switches to SOS mode, you won’t be able to make Calls or send Text Messages from your device. However, you will be able to Call 911 and other emergency services.
1. Enable Roaming Data
If you are outside the area of your carriers network, you won’t be able to make calls unless data-roaming option is enabled on your device.
Before enabling data-roaming, you need to be aware that roaming charges can be excessive and even outrageous in certain cases.
1. Go to Settings > Cellular > Cellular Data Options.
2. On the next screen, move the toggle next to Data Roaming to ON position (Green).
Once Data Roaming is enabled, you should be able to make regular phone calls and send text messages from your device using expensive roaming data.
2. Enable/Disable Airplane Mode
Enabling and Disabling Airplane Mode helps in refreshing the network and resetting wireless antennas on your device.
1. Open Settings and move the toggle next Airplane Mode to ON position.
2. Wait for 30 seconds > Disable Airplane Mode by moving the toggle to OFF position.
3. Switch to 4G or LTE Network
If you are using 5G Network, the problem might be due to 5G network not currently being available in your area.
1. Go to Settings > Cellular > Cellular Data Options > Voice & Data .
2. On the next screen, select LTE or any non 5G Network.
After this, take a look at top-left corner of the screen to see if your device is out of SOS mode.
4. Disable Automatic Network Selection
Sometimes, the problem is caused due to your device being unable to automatically connect to the Service Providers Network.
1. Go to Settings > Cellular > Network Selection.
2. On the next screen, move the toggle next to Automatic option to OFF position.
3. After disabling Automatic Network selection, wait for available Networks to appear on the screen and select your Service Provider’s Network.
5. Remove and Reinsert SIM Card
It is possible that your iPhone has lost contact with the Service Providers network due to its SIM Card being displaced, becoming faulty or damaged.
To check, remove the SIM Card from your iPhone and inspect the SIM Card for visible signs of damage.
If you do not find signs of damage, reinsert the SIM Card back into iPhone and see if the problem is now fixed.
6. Restart iPhone

2. On the next screen, use the Slider to Power OFF iPhone.
3. Allow iPhone to completely Power OFF > Wait for 30 seconds > Restart iPhone.

2. On the next screen, wait for iPhone to check for updates.
3. Tap on Install (if an update becomes available).
8. Reset Network Settings

2. On the pop-up, select Reset Network Settings option.
3. On the confirmation pop-up, tap on Reset to confirm.
