From military communication to commercial success

Viettel was founded in 1989 as a military communication unit under the Ministry of Defense in Vietnam. It wasn’t until 2004 that Viettel officially entered the telecommunications market as a commercial provider. With its strong financial backing from the government and advanced technology, Viettel quickly gained a significant market share and became the leading mobile network operator in Vietnam.

Expansion to other countries

In 2006, Viettel started its international expansion by investing in telecom infrastructure in Cambodia, Laos, and Haiti. This move not only helped to boost the economies of these countries but also increased Viettel’s global presence. Today, Viettel operates in 11 countries, including Myanmar, Tanzania, and Peru, with plans to expand to more countries in the future.

Buying Viettel’s Esim

Viettel was the first mobile network operator in Vietnam to introduce esim technology in 2018. An esim is a digital SIM card that is embedded in your device and does not require a physical SIM card. This makes it convenient for travelers who do not want to switch out their SIM cards when visiting different countries.

To buy a Viettel esim, you will need to visit a Viettel store and present your device with esim capability. The process is similar to buying a physical SIM card, where you will need to fill out a registration form and provide your passport or ID card. The cost of an ESIM is slightly higher than a physical SIM card, but the convenience it offers is worth it for many users.
