In this article, we will show you why your iPhone may show no service and provide effective solutions to fix this issue.

Now that we understand the possible reasons behind the no service issue on your iPhone, let’s explore some effective solutions to resolve it:

Step 1. Swipe down from the top right of the screen to open the Control Center. If you are using iPhone SE/8 or earlier models, please swipe up from the bottom to open Control Center.

Step 2. Look for the airplane icon and ensure that it is not highlighted. If it is, tap the icon to turn off Airplane Mode.

Step 1. Go to Settings on your iPhone.

Step 2. Scroll down. Then tap on Cellular or Mobile Data.

Step 3. Toggle the Cellular Data switch off. Please wait for a few seconds. And then toggle it back on.

Restarting your iPhone can often resolve minor software glitches and connectivity issues. To restart your iPhone, follow these steps:

Step 1. Press and hold the power button (located on the side or top of your iPhone) until the Slide to power off option appears.

Step 2. Slide the power off slider to the right to turn off your iPhone.

Step 3. Once your iPhone is off, press and hold the power button again until the Apple logo appears on the screen.

4.    Remove the SIM card and re-insert it

A faulty or improperly inserted SIM card can cause no service on your iPhone. To check and re-insert the SIM card, follow these steps:

Step 1. Find the SIM card tray. It is usually on the side or top of your iPhone.

Step 2. Insert the SIM card removal tool into the small hole next to the card tray. A paperclip will do. Gently push to eject the card tray from iPhone.

Step 3. Take the SIM card from the tray and inspect it for any damage. If it appears fine, re-insert it back into the tray.

Step 4. Please make sure that the SIM card is properly seated in the tray, then push the tray back into your iPhone until it clicks into place.

5.    Contact your carrier

If none of the above solutions work, it’s important to reach out to your carrier’s customer support. They can check for any network outages in your area and provide you with specific troubleshooting steps based on their network and your account. Follow their instructions and provide them with any relevant information about the issue you’re facing.


6.    Check cellular settings update

Updating your cellular settings can help resolve any compatibility issues and improve connectivity. To check for a cellular settings update, follow these steps:
