[AC Question]

I want to have my phone only get phone calls

When you say calls only, do you mean no texts, or no texts, no email, no other notifications from services like Facebook Twitter and Instagram? It isn't possible but you can turn off notifications, set your notification sound to silent, turn off email notifications in the email app, and the same for SMS, and for the other services under notifications in the settings you can select to disable notifications by app, in the list found there. They will still come to the device but you will never see or hear them.
