Well, I can't seem to get a straight answer from AT&T or Apple. Maybe someone here can help me? I want to start a new account when/if I buy an iPhone but I want to increase my text messages. My current AT&T SMS plan is the 200 Messaging Starter + Unlimited Mobile to Mobile Texting for $9.99/month. Can I add the Messaging Starter (200 messages) + UNLIMITED Mobile to Mobile Messaging plan to a new iPhone monthly plan?
