Follow the tips below to get rid of the “iPhone says No Service” error for good!

Hard Reset Your iPhone

The first step any time you encounter an issue with your iPhone is to hard reset it. This refreshes the device’s memory and clears out any glitches that could be preventing it from connecting to your carrier’s network.

Here are the steps to hard reset based on your iPhone model:

  • iPhone 6s or Older: Press and hold the Lock and Home buttons simultaneously for at least 10 seconds, until you see the Apple logo on the screen.
  • iPhone 7 and Newer: Press and hold the Volume Down and Lock buttons simultaneously for at least 10 seconds. Keep holding them even after the screen goes black and wait for the Apple logo to appear.

Once your iPhone powers back on, try making a call or sending a text to see if the No Service error has disappeared.

Update Carrier Settings

Your carrier periodically sends out updates to the network settings configured on your iPhone. If these settings are out of date, it can sometimes cause connection problems.

Here’s how to update carrier settings on your iPhone:

  1. Open Settings > General > About.
  2. Wait a few seconds on the About screen. If an update is available, you’ll see a prompt to update your carrier settings.
  3. Tap to install the latest carrier update configuration file.
  4. Wait for the update to complete.

This refreshes the network-related software on your iPhone and syncs everything to your carrier’s latest specifications. Check if No Service error goes away afterwards.

Refresh Network Settings

Resetting your network settings can help troubleshoot software and connectivity issues on your iPhone. Here are the steps to refresh network settings:

Reset Network Settings on iPhone
  1. Open Settings > General > Reset.
  2. Tap on Reset Network Settings.
  3. Enter your passcode if prompted.
  4. Confirm that you want to reset network settings.

This will wipe all WiFi networks and passwords stored on your device. You’ll have to reconnect to each WiFi manually afterwards. However, it often resolves glitches that cause No Service errors.

Re-insert the SIM Card

If you recently switched SIM cards or changed carriers, a improperly inserted SIM could be the culprit. Follow these steps:

  1. Turn off your iPhone.
  2. Locate the SIM card slot on the side of the phone.
  3. Use a paperclip or SIM-removal tool to gently pop out the SIM card tray.
  4. Remove your SIM card from the tray, and check for any signs of damage.
  5. Carefully reinsert the undamaged SIM card into the tray, making sure its oriented correctly and sits flush.
  6. Slide the SIM tray back into the slot until it clicks into place.
  7. Turn your iPhone back on and see if No Service error has gone away.

Reseating the SIM card often resolves connection issues caused by SIM card dislodging or improper insertion.

Update iOS Software

Keeping your iPhone’s operating system up-to-date is key. Apple releases periodic iOS updates to fix bugs, patch security flaws and improve connectivity issues.

Update iOS to Fix iPhone No Service

Here’s how to update your iPhone’s iOS version:

  1. Open Settings > General > Software Update.
  2. If an update is available, tap Download and Install.
  3. Enter your Passcode if prompted.
  4. Tap Agree to the Terms and Conditions.
  5. Wait for the update to download and install. Your iPhone will automatically reboot once finished.

Installing the latest iOS version could very well fix the No Service problem, especially if it was caused by a bug in the older OS.
