Abstract: A method comprises: at a control entity configured to communicate with a network: linking a user identifier of a user having an account for call-related information to a hardware identifier of a device to be sent to the user, to produce linked identifiers; loading on the device a limited use token associated with the user that enables only basic call functions on the device, and prevents the device from accessing the account; determining whether the user possesses the device based on the linked identifiers and proximity pairing of the device with a pairing device; and based on determining, either provisioning the device with a full access token that enables full calling functions on the device and grants full access to the account by the device, or not provisioning the device with the full access token to prevent access to the account.
