If your iPhone is showing “No Service” even though you have a SIM card inserted, here are some troubleshooting steps you can try:
Method 1) Restart your iPhone:
A simple restart can often fix many issues, including “No Service” on your iPhone. Press and hold the Power button until the “slide to power off” slider appears. Swipe the slider to power off your iPhone, then press and hold the Power button again until the Apple logo appears.
Method 2) Update carrier settings:
Go to Settings > General > About. If there is a carrier settings update available, you will see a prompt to update.
Method 3) Reset network settings:
Go to Settings > General > Reset > Reset Network Settings. This will reset all network settings, including Wi-Fi passwords and VPN settings.
Method 4) Try removing and reinserting your SIM card:
Make sure your iPhone is turned off before removing the SIM card. Gently insert it back into the SIM card tray and turn on your iPhone.
Method 5) Check your account status:
Make sure your mobile service account is active and in good standing. You can contact your mobile service provider to check if there are any issues with your account.
Method 6) Restore your iPhone:
If none of the above steps work, you can try restoring your iPhone using iTunes or Finder on a computer. Make sure to backup your iPhone before restoring it.
If you are still experiencing “No Service” on your iPhone after trying these steps, it may be a hardware issue and you may need to contact Apple support
