Bubbletone Blockchain in Telecom — the decentralized telecom ecosystem that allows mobile network operators, phone users and service providers to interact directly.


Bubbletone project is developing a decentralized telecom ecosystem aimed at directly connecting travelers and mobile network operators via smart contracts in order to lower the costs of international roaming.

Bubbletone Blockcahin will be built on Graphene Framework, and it will introduce two types of tokens within the its ecosystem:

  1. SDR token, an internal component of the system used only for payments of operators and service providers.
  2. UMT token (Universal Mobile Token), a utility token that will be sold at the ICO and can be listed on exchanges. UMT will be used in Bubbletone Blockchain smart contracts for performing transactions (paying for telecom services on the Bubbletone platform).

Bubbletone platform will have 4 types of members: mobile phone subscribers, operators, third-party service developers and crypto community members.

On the Bubbletone platform mobile network operators will be able to publish their own prepaid tariff plans as smart contracts available to other operators and to subscribers. When user selects an offer, a new smart contract is created with the user’s digital identity and direct payment transactions with the operator.

By using Bubbletone, subscribers will be able to make calls and use data while travelling, retain their SIM-cards and phone numbers.

Bubbletone’s mobile app, Bubbletone Messenger, offers the following main services to its users:

  1. A global marketplace connecting subscribers and local network operators;
  2. Keeping domestic phone number during foreign trips;
  3. Conference calls;
  4. Burning messages;
  5. Local phone numbers in different countries.

Bubbletone Messenger is currently in beta, and it is available on Google Play and in Apple App Store.
