Roaming significantly increases the cost of a phone call. It is not surprising that travelers buy sim-cards of local operators, using the usual number only if necessary.

In fact, the use of roaming harms everyone — operators lose customers when they go beyond the coverage of the home network, the subscribers themselves are forced to purchase local sim-cards, refusing to use the usual number. The creation of Bubbletone Blockchain ecosystem solves the difficulties of both users and operators.

Companies that connect to Bubbletone Blockchain will be able to provide their customers with the opportunity to save their phone number, and therefore revenue for incoming and outgoing calls. Subscribers of the messenger Bubbletone who have chosen a tariff plan, local companies will receive service without charge. The operator themselves will provide services (mobile data transmission) to people coming to the region without incurring the cost of their connection.
