1. The Evolution of Vietnam’s Mobile Networks

1.1 From 3G to Nationwide 5G

Over the past decade, Vietnam’s telecom infrastructure has grown rapidly.

3G became widely available by 2012, offering basic mobile internet access.

4G LTE officially launched nationwide in 2017, bringing broadband-level speeds.

5G began pilot testing in 2019 and has since expanded to all major cities.

Now in 2025, 5G coverage in Vietnam is among the most extensive in Asia, powered by leading carriers — with Mobifone playing a crucial role in nationwide deployment.

1.2 Mobifone’s Legacy and Modern Expansion

As one of Vietnam’s first and most trusted telecommunications brands, Mobifone has evolved from a traditional voice operator into a next-generation 5G data network provider.
Its strategic rollout of 5G towers across the country now ensures:

Seamless coverage in major cities and highways

Stable 4G fallback in rural or remote areas

Excellent data speeds for tourists and digital nomads

This makes Mobifone eSIM Vietnam the perfect companion for travelers seeking both speed and reliability.
