How to set the number of rings before answering on iPhone 16

You....don't set the number of rings. Your carrier sets the number of rings.

Most of them can program more rings....or less rings....but you have to ask your carrier about your options.

Apple is not involved with this.

That's something your carrier manages. Contact them for help with this.

Who is your cell provider?
