For Christmas I purchased a Motorola Rival for my daughter. The phone is great, but she doesn't get caller id. Is this feature not available on her phone, or is there a way to set it up. I have even tried putting pictures on all of her contacts so she would know who was calling, but all she gets in unavailable. Is there anything I can do to fix this? She is still receiving calls for the old owner of the phone number and doesn't want to answer if she doesn't know who is calling! Thanks for your help!!!
