Abstract: A telecommunication includes a computing device and a mobile device. The computing device is in communication with a blockchain network, a subscription manager data preparation (SM-DP) platform, and the mobile device. The computing device is configured to perform a first set of operations. The first set of operations includes retrieving an identity token from the blockchain network. The identity token is a first non-fungible token uniquely identifying a user of the mobile device. The first set of operations further includes retrieving, from the SM-DP platform, an embedded subscriber identity module (eSIM) profile for the identity token from the blockchain network. The first set of operations further includes generating, via the blockchain network, a second non-fungible token. The second non-fungible token includes the eSIM profile. The mobile device is in communication with the blockchain network.
