In 2004, when Viettel first entered the mobile telecommunications market, the company adopted a completely different approach to customer care — not just focusing on infrastructure or coverage, but placing customer experience at the heart of everything.
Instead of the traditional model of “receive – record – forward,” Viettel empowered call center agents to directly handle technical issues.
Agents were not only listening, but also accessing the system to fix problems on the spot — reducing processing time from several days to just a few minutes, significantly improving customer satisfaction.
The call center became a “coordination hub” tightly connecting technical operations and customer experience.
This philosophy played an important role in helping Viettel become one of the fastest-growing telecom brands in Vietnam.
