I have a watch called a Pebble. It has one way communication with my iPhone. It vibrates and displays incoming texts, emails and caller ID on it when my phone is in my purse. I always use it when I travel. This would be the first time I will be taking it to a casino. I know it will be helpful since I cannot hear or even feel my phone go off with all the noise. I know you cannot use a phone when at a table, would this qualify as well as it is only one way?
