How can I add another person into a text thread? I phone six

If I already have a text going with one or more people, how can I add another person into the text thread? I have an I phone six

If the conversation already has two other people in it (other than you), then you can add another person. Open the conversation and tap "Details" and scroll to "Add Contact".

Note that this will work for Group iMessage conversations. It will not work for Group MMS conversations.

If the conversation only has one other person it in besides you, then you cannot add another person.
