BubbleTone - Global TELECOM ECOSYSTEM without intermediaries: smart contracts allow direct interaction between mobile operators, subscribers and service providers. “Blockchain in Telecom” ecosystem provides direct interaction between end-users, mobile operators and service-providers via smart contracts.

It eliminates hundreds of intermediators, dramatically reduces costs of mobile services (up to 10times while going abroad), and saves years and millions of $$ on implementation of the old fashioned and ineffective roaming technology.

The Bubbletone app contains more than 100 functions, each being in high demand by users. For our current project, the most important functions are:

Retaining your mobile number in the app during remote swapping of the SIM card profile. Subscribers will be able to receive incoming calls via an IP channel and also pay for local mobile service bundles in the visited country.

Using Bubbletone as the first client of a decentralized network based on blockchain technology (explained below), which we are developing. Blockchain made it possible for us to radically change the rules of the game: we simply eliminated roaming.

How it works: any mobile carrier could publish its own prepaid tariff plans (“Offers”) as smart contracts. These Offers are visible to all other operators and their subscribers. By selecting an Offer, a new “Request” smart contract is created, with the Digital Identity of a subscriber and Payment transaction.
