Viettel offers 7 days of free VoLTE call experience

VoLTE is a high-quality voice service on 4G, 5G network infrastructure.

Accordingly, all Viettel mobile subscribers using phones without VoLTE feature will enjoy the following incentives to upgrade to phones that support VoLTE: Free 7 days of VoLTE voice experience with 5 minutes of on-net calls/day; 500,000 VND discount when buying Samsung A05, A06, M15; Buy cheap 4G Feature phone models from only 390,000 VND/phone.

This support program aims to encourage customers to switch to 4G/5G VoLTE voice services, which is also one of the next steps to prepare for the complete shutdown of 2G waves in September 2026 and gradually improve the quality of telecommunications infrastructure.

VoLTE (Voice over Long-Term Evolution) is a high-quality voice service on 4G/5G network infrastructure that allows customers to make voice calls with faster call connection time and better sound quality than regular calls on 2G/3G network infrastructure; allowing customers to make voice calls and access 4G/5G data without interruption.
