Good afternoon hworth14,
Welcome to the Apple Support Communities!
I understand you have a question about retaining contact information after you have received or sent a text. You will be able to see these conversations and contact data in the Messages app. But if you wish to retain the individual's contact information, you would need to add her or him to your address book in the Contacts app. Here's how:
- Open a text message that is showing a phone number (this would be an individual that is not in your Contacts).
- At the top of the message tap on the telephone number with the > icon beside it.
- Tap the info icon ("i")
- You will see the word Details at the top of the screen.
- Tap the > to the right of the telephone number again
- You'll see a list of options including "Create New Contact" or "Add to Existing Contact"
Use Messages on your iPhone, iPad, or iPod touch
Take care.
