In Vietnam, formal greetings and titles are important. Address contacts by family name and title (e.g., Mr., Mrs.) until invited to use first names.

Confirm the purpose of your call early and keep conversations brief unless business requires otherwise.

TROUBLESHOOTING

Common Issues When Calling Vietnam from Laos

Resolve common calling problems and understand restrictions on certain numbers.

Call doesn't connect

Verify you've dialed +84 (or 0084) before the area code. Check that you've omitted the leading 0 from the area code. Confirm the local number is correct. Some special numbers (government offices, toll-free lines) may have restrictions on international calling.

Poor connection quality

International calls may experience occasional latency or brief delays. If quality is consistently poor, try calling at a different time or using a different network (switch between mobile and WiFi).

Toll-free and premium numbers

Vietnamese toll-free (1800) and premium numbers may not accept international calls. When possible, use the geographic landline number instead.

Mobile termination rates

Calls to Vietnamese mobile numbers may have slightly higher rates than landlines. Check your carrier's rates for mobile vs. landline before calling.
