Language and Communication in Vietnam

Although Vietnamese is the official language spoken throughout the country, many Vietnamese people speak and understand English, particularly in Hanoi, Ho Chi Minh City and the main tourist areas. As Vietnam attracts many European and Asian travellers, local people’s language skills often include other languages to varying degrees. Vietnamese itself is a challenge to master, but locals are delighted to help foreigners learn a few words to make getting around easier. However, English remains the common currency for cross-cultural conversations.
Thanks to the large flow of visitors, Vietnam’s communication system has many features that make it very accessible to foreigners. As far as phones are concerned, you can get a Vietnamese SIM card at every international airport. Post offices and phone shops are everywhere. The Vietnamese communication network is modern, fast and convenient.
THE VIETNAMESE LANGUAGE
While Vietnamese is the official language, you could say that English is its unofficial second language. With the growth in tourist and business travel, English has naturally become the common linguistic “currency”. As a result, urban centres that receive many foreigners, such as Hanoi, Ho Chi Minh City, Da Nang and islands like Phu Quoc, have many people who speak both languages very well.
That said, visitors may find Vietnamese difficult to learn because it is very different from Western languages. It is a tonal language with six different tones: each tone radically changes the meaning of a word. Visitors unused to tonal languages often struggle with pronunciation at first, but with practice they find that Vietnamese people love helping them perfect their accent.
Written Vietnamese uses the Latin alphabet (Chữ Quốc Ngữ), which is a huge advantage for travellers compared with character-based scripts. However, reading can be tricky because of the many diacritics (accents) on the vowels. Fortunately, road signs are written in Latin characters, and many tourist areas offer menus and literature in several languages. One peculiarity of Vietnamese is that the transliteration of place names can vary, although the use of official names in Latin characters is now highly standardised. In addition to the Northern dialect (Hanoi), there are Central and Southern (Saigon) dialects, but they all use the same alphabet and are mutually intelligible.
VIETNAM’S COMMUNICATION NETWORK
Vietnam’s communication network is one of the most efficient in Southeast Asia. Free Wi-Fi is available almost everywhere (cafés, hotels, restaurants) and the 4G/5G network covers almost the entire country, from the mountains of the North to remote islands.
Telephones (phones in Vietnam)
The system is modern and widespread. Buying a SIM card is extremely cheap and easy. Internet messaging apps (Zalo, WhatsApp, Messenger) are the preferred means of communication.
-
International dialling code: The code for calling Vietnam from abroad is +84. To call abroad from Vietnam, you usually dial 00 followed by the country code.

Local numbers: Numbers often start with 0. When calling from abroad, you replace the initial 0 with +84. For example, a number starting with 090… becomes +84 90…
-
Emergencies: Emergency numbers are short, such as 113 (Police) or 115 (Ambulance).
Mobile phones (SIM and network)
Mobile coverage in Vietnam is exceptional. Almost all foreign phones work in Vietnam if they are unlocked. You can buy a prepaid SIM card for a few euros directly at the airport or in shops in town (Viettel, Vinaphone, Mobifone). These cards usually include very generous data allowances. You can top up your credit easily with scratch cards available in any convenience store (such as WinMart or Circle K) or via mobile apps.
Internet and Wi-Fi
Vietnam is one of the most connected countries. Wi-Fi is considered a free basic service in almost every establishment. Connection speeds are generally very high, so you can stay in touch with loved ones or work remotely with complete peace of mind.
