Enter your friend's phone number, then tap Add Person. If your friend already has a Path Talk account, they will be added to your People List. If they do not have a Path Talk account, you'll be be able to send them an invitation via text message - which you can adjust the language of however you wish. After you have added a friend, you can either message them right away, or add another.

Any friends you add on Path will also appear in your Path Talk People List after they accept your request.
