Accordingly, all Viettel mobile subscribers using devices without VoLTE features will enjoy the following incentives to upgrade phones with VoLTE support:

(2) Reduce 500,000 VND when buying Samsung A05, A06, M15 with package 6V120B
(3) Buy cheap Feature phone 4G keyboards from only 390,000 VND/device.
This support program aims to encourage customers to switch to 4G/5G VoLTE voice service - 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.
Previously, in December 2023, the Ministry of Information and Communications issued Circular No. 20/2023/TT-BTTTT, stipulating that from July 1, 2024, mobile phones using E-Utra technology (4G) manufactured and imported into Vietnam must support VoLTE voice features. This standard aims to ensure that all mobile information terminals allowed on the market meet technical standards, contributing to improving service quality and protecting consumer rights.
Why do you need to switch to VoLTE speakers?
VoLTE (Voice over Long-Term Evolution) is a high-quality voiceover service on the 4G/5G network infrastructure that allows customers to make voice calls with faster call connection time, better quality sound than regular calls on the 2G/3G network infrastructure; helping customers to make both voice calls and access 4G/5G data without interruption.
At the same time, when 2G/3G waves are turned off, voice services on 2G/3G infrastructure will not be able to be used, so it is necessary to switch to VoLTE voice to continue using voice services. Moreover, many foreign network operators have turned off 2G/3G waves, so when customers roaming, they are forced to use VoLTE thoai./.
VoLTE is also a platform to provide new voice services in the future such as waiting video services (mecall), video calls, etc.
Regarding VoLTE voice service, customers do not have to pay any additional fees compared to regular voice services on 2G/3G infrastructure, the packages in use are not affected, and do not consume customer data.
