Stop connected devices from exchanging data
By default, devices that are connected to your mobile hotspot can send data to each other. For example, if you and a friend
have your laptops connected to your mobile hotspot, you could play a game together. If your BlackBerry smartphone uses a
BlackBerry Enterprise Server, depending on the options your administrator sets, you might not be able to exchange data
with connected devices.
On the home screen, click the connections area at the top of the screen, or click the Manage Connections icon.
Click Networks and Connections > Mobile Hotspot Connections > Options.
Clear the Allow connected devices to exchange data with each other checkbox.
