The invention relates generally to the field of network connectivity management, specifically to provisioning and controlling the data access of multiple client devices to application servers via a connectivity management device. The invention includes apparatuses, methods, and systems for automating the management of such apparatus and its associating client devices. The management includes initializing and storing device data, ownership proof, connectivity credentials, and security policies into a management system, such as blockchain digital ledger or device management application server. The stored information is used for auto pairing and authenticating the devices via a second wireless technology and triggering secure connection setup over the first wireless technology. The method further includes changing the credential to establish data connection using the first wireless technology according to the device location and available data cost, detecting security attack events, and generating notifications for high data usage and attack detection results.
