At the request of your network service provider, your device may collect and report Customer Proprietary Network Information, which may include information such as: technical configuration, type, destination, location, and amount of use of any telecommunications services to which you are subscribed. Please see our Privacy Page at www.microsoft.com/mobile/privacypolicy, or contact your network service provider for more information.
4G/LTE might not be supported by your network service provider or by the service provider you are using when traveling. In these cases, you may not be able to make or receive calls, send or receive messages or use cellular data connections. To make sure your device works seamlessly when full 4G/LTE service is not available, it is recommended that you change the highest connection speed from 4G to 3G. To do this, swipe left on the start screen, and tap Settings > Network & wireless > Cellular & SIM. Select the SIM, and tap Properties. Switch Highest connection speed to 3G.
