What is the goal of your project?

The goal of the Bubbletone Blockchain platform is to eliminate all long, complex and costly inter-operator roaming procedures and to create a new market for thousands of telecom carriers opening affordable mobile services for silent roamers. Our Blockchain in Telecom ecosystem provides direct interaction between mobile operators and service-providers via smart contracts.

Is your product already working? Do you have a prototype or a beta version?

We have a working beta version of our messenger application, it’s a fully operable modern messenger.

We also have our OTA platform for downloading third-party mobile profiles via SMS developed and running on a commercial basis with our partners in 80 countries globally.

We are currently finalizing on messenger’s convergence with blockchain to start launching smart contracts. Graphene blockchain platform is being currently developed as well, it’s 80% complete already.

Why do you have a blockchain in your project?

Blockchain made it possible for us to radically change the rules of the game in telecom: we simply eliminate roaming.

Blockchain is the basis of our solution, since the interaction between mobile operators is carried out through smart contracts. There is no need in expensive direct contracts and technical integration between network providers. This allows any cellular operator (including small ones) to quickly (within 24 hours) begin offering their services to subscribers of other operators and to provide subscribers with a global service at local rates.

How is your system going to expand?

The Bubbletone ecosystem will expand through 3 main agents:

  1. New mobile operators;
  2. New users of the BubbleTone messenger;
  3. New service providers (TV, music, cloud services, through bonus packages of mobile operators with several service providers in one package).
What are advantages for Node owners?

Node owners get income from smart contracts processing and also Node price increases itself with the quantity of smart contracts in our ecosystem.

Node is an asset. It’s like you buy house which increases in value and pays rent as well.

What are the advantages of BubbleTone messenger?
  1. For subscribers: make calls and use data during travel worldwide at great local rates with direct connection to local operators. No need to change your Sim or phone number. Access to unique offers from service providers all over the world and a variety of amazing features in BubbleTone messenger (audio/video/conference calls, crypto and fiat transfers within the system, etc.).
  2. For mobile operators: global status at extremely low cost and effort, bigger audience of potential subscribers due to visitors and tourists, more services for subscribers. Increase in revenue through distribution of value-added services
  3. For service providers: larger reach of potential clients, operations and marketing costs cut down.
How do I operate all these other Sims on my phone?

You don’t need any additional Sim cards, it works with just your current Sim. All you need is download BubbleTone messenger, and with its interface you will be able to choose offers from service providers and subscribe or cancel subscription for services at any moment.
