In addition to the function of monitoring health and exercise, the eSim technology enables the watch to make calls, receive messages, and access the internet. It works well with Viettel’s 2G, 3G, and 4G networks and in particular supports voice over 4G (Voice Over LTE).

With eSim technology, the smartwatch can operate independently in any area with a mobile signal without pairing with a cellphone nearby |
With this technology, the smartwatch can operate independently in any area with a mobile signal without pairing with a cellphone nearby.
This helps users feel more comfortable during outdoor activities while still keeping in touch with others, especially in emergency.
Each smartwatch has a private subscriber number or the same number as a mobile phone subscriber, which is called Multi-Sim service or One Number.
The Multi-sim / One Number service is the common trend among mobile operators around the world when deploying voice service on smartwatches.
Viettel is working with major smartwatch manufacturers to test numerous devices, ensuring full compatibility when operating on its network.
It is expected that Viettel customers will be able to officially use the eSim service on their smartwatches in the fourth quarter of this year.
Mr. Le Ba Tan, Deputy General Director of Viettel Network, said that after testing the eSim service on mobile phones, Viettel will continue to test eSim on smartwatches in a bid to help customers have new experiences and catch up with the latest technology trends around the world.
“We will test and apply many other advanced IoT technologies to serve the connection needs of people in the time to come,” he added.
Some smartwatches already are compatible with eSim, such as Samsung Galaxy/Gear S3 or Apple Watch Series 3/4, but they are only available in certain markets.
Smartwatches on sale in Vietnam are able to receive calls via Bluetooth connections with a mobile phone only. If the two devices are far apart, the watch cannot field the call.
