If your iPhone says "No service", you can't make or receive phone calls, send text messages, or link to the Internet unless you're using Wi-Fi. It's easy to forget how essential our iPhones are to our lives — until they're not working. I'll explain why your iPhone says No Service in this article, and show you exactly how to fix the problem.

Usually, No Service issue is caused by the below reasons:

  • SIM card is damaged in some way or not placed in the correct way
  • SIM card is not loose or well-connected inside the SIM slot or gets dusty.
  • The signal of your mobile service provider is too weak where you use your phone
  • iOS needs to be updated
  • Other third-party software impacts mobile service.

In these cases, you can first try to switch airplane mode on and then off or restart your phone to see whether the issue is fixed. If not, proceed to try the below five solutions.

Check your SIM card

To remove the SIM tray from your iPhone, use a SIM tool or straightened paper clip. Test your SIM card in another phone to decide whether there is a fault in your iPhone or the SIM card itself that triggers the Search or No service issue. You may need to consider ordering a replacement from your cell phone provider if the SIM card in another unit still doesn't work. Otherwise, our measures will proceed below.

Check SIM Card In iPhone

When removing the SIM tray, look to the liquid indicator tab within your iPhone. It should be a little tiny little button. If it turns orange or pink your iPhone may get damaged to liquid.

Reset network settings

Your iPhone can reconnect to carrier and Wi-Fi networks after you update Network Settings. This means that you may need to re-enter your Wi-Fi password and make sure you have it before going any further.
