Thanks to worldwide improvements in cellphones and the infrastructure for using them, it's now easier for people to stay in touch when overseas. It can get expensive, depending on your service provider and calling plan, but calling the United States from Vietnam is easy with the correct sequence of numbers.
Ask your service provider about the compatibility of your phone with the network capabilities available in Vietnam. According to Verizon, Vietnam supports 3G network service, so any 3G-capable phone should work there. Also ask about the calling plans and rates that apply when calling from Vietnam.
Dial 00 to begin the calling process in Vietnam, followed by the country code for the United States, which is 1.
Dial the 10-digit phone number as you would within the U.S., beginning with the area code. For example, to call a number in Montana, dial 00-1-406-555-1234.
Tips & Warnings
- If you don't have a suitable cellphone or calling plan, your least expensive option will likely be a calling card.
