Staying in touch with family and friends while you are studying in the U.S. is naturally important to you and your loved o­nes. E-mail makes it possible to stay in contact regularly and inexpensively. However, you will also want or need to speak by telephone sometimes. There are several options for staying in touch by phone:

1. Using a land line with a long distance service provider. In the U.S., long distance telephone service is generally privatized, with various long distance carriers offering different package options. An advantage to using your land line is that you can call from the comfort and privacy of your room at a time that suits you; however, this option is often more expensive than using a pre-paid phone card or internet-based phone card.

2. Phone cards. Phone cards can be purchased for a set amount at many convenience stores or specialty stores. They generally do not include additional charges besides the given rate per minute. Some are especially for calling Asia, and can be used at pay phones. Before purchasing a phone card, make sure it can be used to call Vietnam. Phone cards can also be purchased o­nline through internet based companies. In this case you will be given a phone card number rather than an actual card. You can usually add money to both virtual and hard copy phone cards o­nce you have reached your limit.

3. Mobile phone. U.S. mobile phone companies use different technologies than the rest of the world, so it is often the case that you will not be able to use your cell phone in the U.S. Your best option may be to purchase a mobile phone o­nce you arrive, for use in case of emergencies, and because public telephones less and less available. The website http://www.letstalk.com/ compares major brands and their plans. If you have a mobile phone that works in the U.S. you can buy a SIM card at many outlets. Not all SIM cards work internationally so be sure to ask about this. Calling internationally o­n a mobile phone is in general the most expensive option.
