A method and device is provided that determines whether an antenna is electrically connected to its respective coupling device. The first side of the device includes coupling device, a mechanical switch, and an application processor. The second side includes an antenna contact that that is creates an electrical connection with a coupling device on the first side when the first side is securely attached to the second side. The mechanical switch is configured to be in an “open” state when the antenna contact does not make an electrical connection with the coupling device. Each mechanical switch is configured to be in a “closed” state when the antenna contact does make an electrical connection with its coupling device. The application processor determines the state of each mechanical switch. When any switch is an “open” state, it provides a notification on an interface of the mobile device.
