The issue can be related to your carrier or your iPhone. Nevertheless, we will cover every trick and fix the issue.
1. Enable and Disable Airplane Mode
Using the Airplane mode trick, you are rebooting your iPhone’s network connection. Swipe down from the upper right corner, open the Control Center, and enable Airplane Mode. Those using iPhone with a physical button can swipe up from the bottom part. Keep the iPhone in Airplane Mode for around 10 seconds and disable it from the same menu. Try calling someone, and the call should go through.
2. Make Sure to Have a Proper Network Connection
You need to ensure enough network bars to complete a successful call. Glance over the upper right corner and check if you have a couple of network bars. If you don’t have network bars on your iPhone, you will continue to see call failed error.
3. Reinsert SIM
Did you drop your iPhone recently? That might have messed up SIM card adjustment on iPhone. Use the SIM injector tool, remove the SIM card and reinsert it properly. Once you get back network connectivity on your iPhone, try calling someone.
4. Check Carrier Plans
