Vietnamobile provides services for making phone calls on Wifi networks to both off-net subscribers

Recently, Vietnamobile announced that it has cooperated with Samsung, the world's leading electronic brand, to become one of the first operators to offer both voice and wireless network services for both internal and external network subscribers VinaPhone, MobiFone, Viettel.

Two new Vietnamobile voice services include:

• VoLTE is a 4G voice call function with high quality and realistic sound.
• VoWifi is an uninterrupted voice call function using Wifi even when there is no phone wave.

Two VoLTE and VoWifi voice services provided by Vietnamobile are completely free. However, currently the two features are only integrated on Samsung Galaxy S10, S10 +, SE models and all new models later.

With these two new services of Vietnamobile, customers can use Wifi to make free calls to Vietnamobile subscribers whether in Vietnam or abroad.

Vietnamobile subscribers use Wifi waves to use network calls to other networks such as VinaPhone, MobiFone, and Viettel will have to pay charges like normal domestic calling rates.

This is a very useful service to help overseas subscribers can call domestic subscribers at a price only equal to domestic rates, much cheaper than regular services.

Currently, Vietnamobile is cooperating with a number of other carriers to provide this service to its subscribers.

Vietnamobile's coverage is worse than other carriers. With the provision of these two new services, Vietnamobile is seeking technical methods to limit this drawback.
