Depending on your device, a Nokia Account may be created for you, or you might need to sign in with your existing Nokia Account when you first use your device. During the activation process your user name, email address, mobile number, unique mobile device identifier and subscriber identity information will be sent to Nokia, and then we may associate this information with your Nokia Account. This information may be used to activate your warranty and certain software licenses and to send you personalised messages, for example emails, text and other communications about Nokia’s products and services – you may unsubscribe from these messages at any time, by following the information in the message you receive.
