VIETTEL CUSTOMER SERVICE

More than just a workplace,
we creates employee experience.

Our philosophy

At Viettel Customer Service, we believe that people are at the center of every experience. Technology can create speed and scale, but only people can bring understanding and the moments that truly connect with customers’ hearts. That is why we invest in every employee as if we were investing in the experience of millions of customers.

We cultivate an environment where each person is heard, understood, and inspired to grow every day. A place where the PROSPECT spirit - Professional, Responsible, Open, Supportive, Proactive, Empathetic, Collaborative, Trustworthy - is not just a set of values, but the way we live and work.

We believe that one happy employee can create millions of happy customers. EX is not a program — it is a culture that encourages learning, embraces differences, empowers innovation, and unites us in creating the best customer experiences anywhere in the world.

At Viettel Customer Service, people work for people - and that is what enables us to create experiences that are complete, human-centric, and enduring.
