How can I remove red badge call icon on my iPhone 16 Pro Max?

The red notification badge on the Phone app icon can indicate a missed call and/or a voicemail. If a missed call, you need to just open the Phone app and look at your Recents list to see the missed call, that should clear it. If that doesn't clear it, then it probably indicates a voicemail, check that.

No .. what’s Siri method

Read the first reply in the thread. That’s where I told you what it is. But I’ll tell you again:

Ask Siri to “Hear all new voicemails” and “Check for missed calls” Let us know if this worked.

Hello!

A shot in the dark, but have Siri read all unread voicemails, check all unanswered calls, that sort of thing. Report back if you can’t resolve the issue.

Have you Force Restarted your iPhone --> Force restart iPhone - Apple Support

Restart and Force Restart aren't the same. Did you do what I suggested? Which means you have to open, read and follow the directions in the link I provided.
