Bubbletone Blockchain in Telecom is the first decentralized telecom ecosystem that allows mobile network operators, phone users and service providers to interact directly. We directly connect mobile network operators and end users globally on our blockchain-based marketplace. With BubbleTone Blockchain, travelers can swiftly become legitimate local customers of any foreign operator in the country they are traveling to. They don’t need to replace their SIM card, and they retain their home number. Any mobile carrier can publish prepaid plans as smart contracts on BubbleTone Blockchain. These offers are visible to all other operators and their subscribers. When subscriber selects offer, a new smart contract is created with the subscriber's digital identity and payment transaction directly to foreign operator.
