One of the easiest ways to fix the problem of call failed on your iPhones is to dial *#31# and Bob is your uncle!
Toggle Airplane Mode
Swipe up the Control Centre from the Home Screen and put your iPhone on Airplane Mode and wait for few seconds then turn it off. You can also do this by going to Settings, where Airplane Mode is the very first option. This is one of the efficient ways to fix the issue.
Close Unnecessary Apps
Some users have the habit of keeping so many apps open simultaneously. This, of course, drains your memory and results into call failing. A smart user will never do this. Close unnecessary apps on your iPhone by double pressing home button and swipe up the apps. Agreed that your phone is latest and boasts many powerful features, but it is always wise to save some memory.
Date & Time
This might sound funny, but it works when you tamper with Date & Time in your iPhone. Well, as a matter of fact, you don't actually have to interfere with date and time; just go to Settings → tap on General → select Date & Time. Now, turn off Set Automatically. Finally, select your home town manually and you might fix the problem.
Caller ID option is subject to the mobile service provider you have opted for. Hence, this might not work on all iPhones; you can still take a chance. Go to Settings and tap on Phone; now tap on Show My Caller ID and toggle it on. If this fails to work, you can also turn off Call Forwarding and Call Waiting options.
This could be the one-stop solution for many problems related to your iPhone; whenever something happens, we tend to restart the device as we used to do while using laptop or desktop computers. Hold the Wake/Sleep button (on the right side of your iPhone) and turn your phone off. After a few seconds, hold the button again to turn it on.
