When I try to assign a ringback tone to a specific contact I am getting an error that says "invalid mobile phone number". The number is right and the ringback tone will assign to another contact. Why not this one?
Is there something unique about the number? Different carrier? Do calls from that number deliver the caller id? Have you tried deleting the contact and adding it back?
Thank you. I didn't try removing contact and adding it back in. That worked. Merry Christmas
