My Droid X won't send text messages to one of my contacts who also has Verizon when I am in North Carolina. I can send her picture messages from NC but everytime I try to send her a text I get a message saying "text not sent". I can receive messages from her but cannot send them. I don't have any problem when I am at home in Virginia but in North Carolina it won't send my messages. I don't think it is a problem with my plan or coverage bc I can send messages to everyone else in my phonebook, she is the only person that my phone won't send them too. It makes no sense to me. HELP!!!!!
