- Go to Settings > General > Software Update. If an update is available, download and install it.
- Reset Network Settings (Use with Caution): This will erase all saved Wi-Fi passwords and other network configurations, so you’ll need to re-enter them.
- Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings.
- Check Your SIM Card:
- Power off your iPhone.
- Use a SIM ejector tool or a small paperclip to remove the SIM card tray.
- Check the SIM card for any damage.
- Reinsert the SIM card and make sure it’s properly seated.
- If you have another device, try your SIM card in it to see if the problem is with the SIM or your iPhone.
- Contact Your Carrier: If the problem persists, contact your cellular carrier. There may be an issue with their network in your area or a problem with your account.
- Contact Apple Support: If you suspect a hardware problem with your iPhone, contact Apple Support or visit an Apple Store.
By systematically following these steps, you should be able to identify and resolve most issues related to repeated call failures on your iPhone.
Checking Network Settings
Check your cellular data settings. Make sure cellular data is turned on. If you’re using Wi-Fi Calling, make sure it’s enabled and that you have a stable Wi-Fi connection. Sometimes, resetting your network settings can help. This will erase saved Wi-Fi passwords, so you’ll need to re-enter them.
Software Updates
Make sure your iPhone is running the latest version of iOS. Software updates often include bug fixes that can improve call quality and reliability. Go to Settings, then General, then Software Update to check for updates. Keeping your software current is good practice for security and performance.
Hardware Concerns
If none of these steps work, there might be a hardware problem. This could be an issue with your SIM card or the phone’s antenna. Try removing and reinserting your SIM card. If you have another phone, try using your SIM card in that phone to see if the problem is with the SIM or the phone itself. If you suspect a hardware problem, contact Apple Support.
