About Voop
Voop is a B2B neo-telco founded to build vertical use cases and offer value-adding telecom-based products to businesses. In just six months, we have built:
A full UK MVNO in partnership with BT/EE.
A global data network supporting eSIM-based data packages across the world and IoT use cases.
A management platform that integrates with any mobile network, enabling full control and orchestration of mobile connectivity and device management.
Traditional telcos are dying because they fail to innovate. They provide commodity connectivity without differentiated software that solves real-world problems. Voop is here to change that.
