Wifi, teléfonos y adaptadores
Plan ahead for ways to communicate internationally. Today, most hotels offer Internet access for free or at low cost. You can also look for cafes and coffee shops with free Wifi, such as Starbucks. Travelers can easily stay connected through thier own internal hotspots if thier carrier includes them in the service. Remember that you'll need a plug adapter for U.S. sockets to keep your devices charged.
The only cell phones that work inside the United States are GSM tri or quad band models. An inexpensive way to make calls is to buy a compatible SIM card for the USA (sold by carriers like AT&T and Cingular) or to buy a no-contract, prepaid U.S. phone with a set number of minutes (available from Virgin Mobile, T-Mobile, AT&T and more). Make sure if you will be calling internationally that your phone plan allows that.
Phone numbers in the U.S. start with a three digital area code followed by a seven-digit number. To call long-distance from state to state, you may need to first press 1. 1 is the international country code for USA if calling from abroad. Dial 011 to make an international call from within the U.S., followed by the country code and phone number.
