Stertell is a global telecommunication company which provides a wide range of wholesale messaging services and high level of protection for its customers around the world. We create business opportunities for our customers and reduce their operational and direct costs. Stertell is an SMS hub - an intermediary between a service that needs to send SMS traffic to its customers, and mobile operators that are used by the service's customers. The service gets the opportunity to send SMS to all its subscribers from different countries, entering into an agreement with only one SMS-Hub, which has a connection to all operators instead of signing contracts with each operator separately.
