If you want to add a person to a group text on your iPhone, there are a few steps you can take. First, open the Messages app and tap on the three lines in the top left corner of the screen. Then, select “Add Contact.” Once you’ve added the contact, tap on “Send.” You’ll now see a list of people in your group text who have also been added. To add them all at once, just type their names into the text field and hit send.
