Sumo 4G V1S has 4 color versions for customers to choose from: black, red, dark blue and green.

Launched at the right time, just over a month before the whole country stops providing services for 2G phones, Sumo 4G V1S is an outstanding basic phone model of Viettel with integrated 4G, with fast, seamless and stable connection and call quality.

Simple to use, with memory card slot support and good battery capacity, along with compact size, easy to carry, is considered suitable for the majority of 2G customers who are still hesitant to change their device due to fear of using a smartphone, especially the elderly and children.

In addition, although it is almost a "brick" phone and has a reasonable price, it is equipped with the ability to connect to popular applications such as Youtube, Tiktok, Weather, etc. Sumo 4G V1S will certainly be welcomed by customers, helping network operators and customers to soon "finish" the roadmap to upgrade 4G phones, preparing for the plan to completely turn off 2G waves in the near future.
