There can be several reasons why your phone is not making calls on your iPhone. Here are some steps you can take to troubleshoot the issue:
1. Check your network connectivity: Ensure that you have a stable network connection, either through Wi-Fi or cellular data. If you're experiencing network issues, try restarting your phone or toggling Airplane Mode on and off to reset the connection.
2. Verify your phone settings: Double-check that your phone is not in Airplane Mode, which disables all wireless transmissions, including calls. You can find this toggle in the Control Center or the Settings app.
3. Check for any call blocking or Do Not Disturb settings: Make sure you haven't accidentally enabled call blocking or enabled the Do Not Disturb mode, which silences calls and notifications. These options can be found in the Settings app.
4. Ensure your phone has cellular coverage: Ensure that you are within an area with sufficient cellular coverage. If you're in a weak signal area, try moving to a different location or contacting your carrier to inquire about any network issues in your area.
5. Verify your contact's number: Check if you've entered the correct phone number for the person you're trying to call or if you have any existing blocks or restrictions on that specific contact.
6. Restart your iPhone: Sometimes, a simple restart can resolve software glitches. Try turning off your iPhone completely, then turn it back on after a few seconds.
7. Update your iPhone software: Make sure you're running the latest version of iOS (currently iOS 16) on your iPhone. Go to the Settings app > General > Software Update to check for any available updates. Updating your software can fix bugs and improve overall performance.
8. Reset network settings: If you're still experiencing issues, you can try resetting your network settings. This can be done by going to Settings > General > Reset > Reset Network Settings. Keep in mind that this will remove saved Wi-Fi passwords and other network configurations, so you'll need to reconfigure them afterwards.
If none of these steps resolve the issue, it may be helpful to contact Apple Support or reach out to your carrier for further assistance. They can provide you with additional guidance tailored to your specific situation.
