Tips for clear & uninterrupted calls

Whether you're reaching Vietnam for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.

HD audio for Vietnam calls
Hanoi routes support G.722 wideband on East Asian carriers — an HD-compatible headset delivers noticeably clearer voice on these high-traffic transoceanic links.
Connection quality to Vietnam
Hanoi is ~8,839 km away — latency runs 280–310ms. Use wired ethernet to eliminate Wi-Fi jitter on this long-haul path.
Best time to call Hanoi
Schedule Vietnam calls during Hanoi business hours — 09:00–17:00 Asia/Ho_Chi_Minh — your contact will be at their desk in a quiet space rather than taking the call on the move.

FAQ

Questions about calling Vietnam, answered.

Everything a business or traveller needs to know before dialling Vietnam (+84). Can't find an answer? Our team is one click away.

Q1.What is the country code for Vietnam?

Vietnam's international calling code is +84. Dial it immediately after your exit prefix and before the local subscriber number whenever calling from outside Vietnam.

Q2.What is the best time to call Vietnam?

Tuesday–Wednesday, 9:00–11:00 AM ICT (UTC+7) is the sweet spot. Vietnam runs on Indochina Time year-round — fixed at UTC+7 with no daylight saving. Ho Chi Minh City and Hanoi business opens at 8 AM. Avoid Tết (Vietnamese Lunar New Year — a 5–7 day national shutdown, late January/early February), National Day (September 2), and Reunification Day (April 30).

Q3.How do I call a mobile number in Vietnam?

Vietnamese mobiles are 10 digits starting with 03x, 05x, 07x, 08x, or 09x. Drop the leading 0 — dial +84 then the remaining 9 digits. A typical Vietnamese mobile: +84 91 234 5678.

Q4.What is the + sign for when dialling Vietnam?

The + replaces your local international exit code. When you call Vietnam using +84, your carrier automatically substitutes the correct exit prefix (00 in Europe, 011 in North America, 0011 in Australia) before the call goes out.

Q5.What time zone does Vietnam use?

Vietnam uses the Asia/Ho_Chi_Minh time zone. Factor in the Hanoi local time before placing calls — the best window for business calls is typically 09:00–17:00 Asia/Ho_Chi_Minh.
