Hi Ricardo. My name is*****'m sorry that you are having this problem. It would be my pleasure to assist you with this. As long as the phone is turned on and has a charge, and is still activated with the cell phone carrier you will hear it ring and chime. However, if it shows that it is disabled then you will not be able to get in to the phone to use it. Can you tell me please the exact model of your iPhone?
Also, does it just say iPhone is disabled or does it say "iPhone is disabled. Connect to iTunes"?
