Vacationing in the U.S. Virgin Islands provides you a vision of paradise. While you're sunning at Coki Beach and island hopping, you want to make sure that you are able to use your cell phone in the case of an emergency. Using a cell phone in the U.S. Virgin Islands is easy if you follow the correct procedures.
Ensure that your cell phone charger has the correct plug for the U.S. Virgin Islands. the U.S. Virgin Islands uses the same plugs as the United States, so unless your charger was purchased in another country, you should not need a plug adaptor. If your charger has a different plug type, purchase plug adaptors "A" and "B" from an electronics store before you leave home so that you can charge your cell phone while in the U.S. Virgin Islands.
Use a transformer that can handle 115 volts, which is the voltage used in the U.S. Virgin Islands, when charging your cell phone. Your cell phone will likely fry if you do not use the correct transformer.
Call your cell phone provider to make sure that they offer phone coverage in the U.S. Virgin Islands. Ask to be upgraded to international roaming.
Consider renting a cell phone or SIM card to use with your personal cell phone if your cellular company does not offer coverage in the U.S. Virgin Islands.
Know how to dial locally within the U.S. Virgin Islands. The islands all share the same area code, so you only have to dial the phone number with no prefixes.
Know how to call the United States from the U.S. Virgin Islands. First dial "011" (this is the international prefix to dial outside of the U.S. Virgin Islands). Then dial "1" (this is the international code used to dial to the U.S.). Follow that by the area code and phone number.
