When visiting Vietnam, it's helpful to learn basic Vietnamese phrases such as 'Xin chào' (Hello), 'Cảm ơn' (Thank you), and 'Xin lỗi' (Sorry). To easily pick up some local words, tourists can use language learning apps like Duolingo or Babbel, or refer to websites like learningvietnamese.net for basic expressions and audio resources.
For connectivity in Vietnam, most hotels, cafes, and restaurants offer free Wi-Fi, but the connectivity speed may vary. It's advisable to purchase a local SIM card for cellular coverage, which can be easily obtained at the airport or local stores. Vietnam uses the Type A, C, and F power outlets, so be sure to bring the appropriate plug adapter. The voltage requirement for electronics is 220V.
The local currency in Vietnam is the Vietnamese dong (VND). It's recommended to exchange currency at authorized banks, exchange counters, or withdraw from ATMs to get the best rates. Credit cards are becoming more widely accepted, especially in upscale establishments. While mobile payment options like Apple Pay and Samsung Pay are gaining popularity in major cities, it's always advisable to carry some cash for smaller transactions and at local eateries.
