When will my iPhone be active?
Your iPhone will be ready as soon as you sign up with AT&T and complete the activation process. If you are signing up for new service and you select a new AT&T mobile phone number, your iPhone may be ready to receive phone calls in just minutes. If you transfer an existing AT&T mobile phone number, it may take a few hours to receive calls. And if you transfer a number from another carrier or from a land line, it may take longer. While waiting for that process to complete, you can make calls but not receive them. You will receive email status updates and an SMS text message when the transfer is complete.
