Promoting the journey of popularizing 5G
Pioneering the launch of the first 5G network in Vietnam, Viettel Telecom aims to cover 5G by 90% of the population by the end of 2025, attracting 12 million 5G subscribers.
Viettel Telecom representative said: 5G is not only a technological advance, but also a foundation to create a more comprehensive connected life. With practical incentive policies, Viettel hopes that all users can easily access and experience 5G, thereby promoting Vietnam's rapid progress in the digital age."
Cooperating with leading smartphone brands is an important step of Viettel to contribute to expanding the 5G device ecosystem and bringing 5G closer to users nationwide. In previous years, most 5G smartphones cost over 15 million VND, making common users still hesitant to switch. However, customers can now access 5G devices at the lowest price of only 2.5 million VND (Samsung A06 5G), making upgrading easier and more popular. This context, along with policies to support devices and donate data from Viettel, is contributing to accelerating the popularization of 5G in Vietnam./.
