An apparatus for securing communications includes a processor and memory storing executable computer code causing the apparatus to at least perform operations including receiving a request to activate a service transferring communications of a cellular network to a wireless local network. The computer program code may further cause the apparatus to provide an activation key to a device responsive to an indication that the device is authorized to utilize the service based on determining an identifier(s) of the request is valid. The computer program code may further cause the apparatus to provide a private key to the device, to enable the device to utilize the private key to subsequently register to transfer communications of the cellular network to a wireless local network(s), responsive to receiving a message for the private key from the device and a message from the cellular network.
