Incoming/outgoing calls fail on iPhone 11 Pro Max

KathyN Said:

"Incoming/outgoing calls fail on iPhone 11 Pro Max: Recently, calls made to me fail after I answer. When I call others, the same thing happens. There is also no record of the calls, even though I answer the call or the other party answers. They are not able to hear me, and I can't hear them. Then the call fails."

Troubleshooting Calls:

A. Start Here: If you can't Make or Receive Calls on your iPhone - Apple Support

B. "No Service":

Is "No Service" shown on the top-left corner of your screen? If so, go here to fix that: If you See No Service or Searching on your iPhone or iPad - Apple Support

C. Install a Cellular Update:

It might be prompting you for a cellular update to install. So, go here for that. Update your carrier settings manually on your iPhone or iPad - Apple Support

D. Update the iOS Using a Computer:

• Use my User Tip:  Update your iPhone Using a Computer - User Tip
• IMPORTANT: If you have an option to update, however, then be certain you backup your iPhone first. That way, you will have something to restore your iPhone from should anything go wrong with the update

Thank you for the followup reply.

Update Immediately, Backing Up, First:

Update your iPhone to iOS16. Update have bug fixes and feature on-ons. Note that only the latest update will install (iOS16.0.2 as of this reply). iOS15 and before are no longer available.

A. Time to Update iPhone:

That depends on the capacity, and how much has to be modified to operate with the new iOS. So, perform this while at home, with nothing on your schedule.

B. So, Update Using a Computer:

For a more reliable connection, try updating using a computer... Use my User Tip:  Update your iPhone Using a Computer - User Tip

Have you contacted your carrier?

Best of luck!
