Contact your network provider
When you contact your service provider, make sure that:
- Your account has been set up to use your iPhone.
- There aren’t any localised service outages.
- Your account doesn’t have a billing-related block.
- Your calls don’t have errors on the network provider system.
Update your software
Check your settings
If you can’t make or receive calls on your iPhone, follow these steps, testing after completing each step.
Check your network settings
- Reset your network settings. Go to Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings. This will erase all current saved settings, including Wi-Fi passwords, preferred networks and VPN settings.
- Try to make or receive calls in another location.
Check your iPhone settings
- Turn Airplane Mode on and off. Go to Settings and turn on Airplane Mode, wait five seconds, then turn it off.
- Check Do Not Disturb. Go to Settings > Focus > Do Not Disturb and make sure it's off. Find out how to use Focus on your iPhone or iPad.
- Check for any blocked phone numbers. Go to Settings > Phone > Blocked Contacts.
- Check Call Forwarding. Go to Settings > Phone > Call Forwarding and make sure it's off.
- Check Silence Unknown Callers. Go to Settings > Phone > Silence Unknown Callers. If this setting is turned on, a caller must be listed in your Contacts or Recents. Or they must have shared their number in the Mail app or sent you a message using that number in order for their call to go through. Add their number to Contacts to ensure the phone rings. Calls from some third-party apps may not go through.
To avoid missing calls from a contact, add their number to Contacts to ensure that your phone rings.
- Find out what to do if "No Service" or "Searching" appears in the status bar.
- If you still can't make or receive calls, contact Apple Support, then follow the steps to complete your request.
