If you've been calling someone and they don't take your call, it may be because they don't have news and don't want to talk with you. One thing you can do is use *67. Enter *67 before you dial the number and it turns off caller-id for that call. It means the person on the other end doesn't know it's you calling. Of course, if they're like me, they may not be willing to answer a "blind" call. But if they haven't been answering before, nothing ventured nothing gained.
It worked for us, and we got a status update.
