Is your iPhone returning a “call failed” error when dialing a contact? I have provided some troubleshooting tips in this guide to fix this issue quickly. Primarily it may be an issue with your network provider.

For example, if the network in your area is down, then not only you but everyone else using the same network would be facing the same issue: not being able to place a call.

Often users block a contact, and in such cases, you cannot call from your iPhone to a blocked number. It could be a random bug that is happening on your iPhone.

This means the version of iOS running on the iPhone may be faulty. For example, if you put in a new SIM card and do not insert it properly, it won’t establish connectivity with the service provider.
