"iphone 13 pro. Every phone call is dropped after I downloaded latest update. Never happened until this last update. Can't use phone for business anymore. Calls dropped multiple times after call backs. This is bad"

Troubleshooting Dropping Calls:

A. 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

Also...

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
