Tips for Calling Internationally from Vietnam

If you are calling internationally from Vietnam, first dial 00, followed by the country code for the country you are trying to reach. Use international phone cards for the best bargains when calling from Vietnam. Calling from local post offices are cheaper than using your hotel’s telephone service, but calling cards still offer the best international rates.

For domestic calls, consider calling from the post office, where public phone service is affordable.  Another option is to buy a domestic phone card at the post office or any phone company branch.  You will usually get a rate of about 1,000 VND per minute. Hotel phones are to be avoided; they are almost always significantly more expensive.

Internet phone service is another option, and it is available at most Internet cafes. The cards used may offer rates as low as 3,000 VND (20¢) per minute, but you may have to use them at the shop where you purchased them, and there may be a surcharge.  In addition, the phone quality varies widely, and there may be a delay.

Internet cafes are easy to find in urban Vietnam and rates tend to be very cheap, often less than 4,000 VND per hour.  You may find service in rural areas, but rates will likely be higher.
