If you see a message saying No Service on iPhone, you probably can’t make or receive calls, and all you get is that error message. This is an indicator of several potential issues. You could be having a problem with the cell phone carrier’s service plan, a misconfigured setting or hardware issue with the phone.
There isn’t one particular problem that’s causing your iPhone not to have service, but you can troubleshoot the issue by trying the easiest and most likely steps. These include a simple setting change like cellular settings or disabling Airplane/flight mode.
In some common cases, the iPhone may need an update on the cellular settings via a software update from your phone’s service provider, or resetting/replacing the SIM card. Often times, the issue is with the phone carrier’s plan so you may need to call them to fix it.
Here’s a troubleshooting guide you can use when your iPhone has no service.
What to do when you get no service on iPhone
Before we try changing any of your phone’s settings or other advanced solutions, there are a few simple and quick things you can try to fix the problem.
Preliminary fixes
- Disable Airplane mode. This disables the WiFi and cellular service, so if the flight mode or airplane mode is on, make sure you turn it off at the top right of the iPhone screen. Toggling it off and then on again can also help bring back lost service.
- Check that you’re within the coverage area of your mobile provider. Sometimes if you’re underground, deep inside or outside an urban area, you may get no service on iPhone. You can check your phone’s signal strength to confirm it.
- Restart the phone to wake the cellular service and restore it back to a functioning state. If you have poor service, try to turn on WiFi calling on your zone for your wireless service provider. If you’re in a cellular dead zone, a signal booster may help amplify the signal so you can use the phone normally.
Check with your carrier for a settings or service update
Occasionally, carriers release updates that impact how you connect to the mobile network. It could be that your service is affected by an update you need to install on your phone. Also contact your carrier and ask about any problems or local outages with the service plan.
Reset network settings
Your iPhone’s settings may have been corrupted such that you get no service on the device. Resetting it back to factory conditions can help resolve the issue. Verify the cellular settings, and then check Settings>Cellular and check that the Cellular Data is on and toggle it off and on again.
Remove or replace SIM card
Your SIM card may not be working well because it’s damaged or isn’t seated properly. Check for damage and clean it gently by blowing on it, or wipe it with a cotton cloth or swab and replace it.
If nothing works, take the iPhone for service by Apple or contact Apple Support for further assistance where you can’t fix on your own.
