How to Add Favorite Contacts on iPhone
The preinstalled Phone app on iPhone makes it easier to call and text the people you talk to most by making them Favorites. When someone is a Favorite, just tap their name to instantly start a phone or FaceTime call, or open a new text message or email.
Tap Favorites at the bottom of the screen.
Select the contact you want to add to the favorites list. You can find them by searching, scrolling, or tapping a letter on the right side of the screen.
