Whether you're snorkeling in Cozumel or horseback riding on one of Mexico's sublime beaches, you should make sure you can use your cell phone in an emergency. Follow these steps.
Ensure that your cell phone charger has the correct plug for Mexico. Mexico uses the same plugs as the United States, so unless your charger was purchased in another country, you shouldn't need an adaptor. If your charger has a different plug type, purchase plug adaptors "A" and "B" from an electronics store before you leave for Mexico.
Charge your phone with a transformer that can handle 127 volts, which is the voltage used in Mexico. Your cell phone likely will fry if you do not use the correct transformer.
Ask your cell phone provider whether they offer phone coverage in Mexico. Request an upgrade 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 Mexico.
Learn how to dial locally within Mexico. Unless your cell phone has the same area code as the number you are calling, dial "01," the area code and the phone number.
Learn how to call the United States from Mexico. First dial "00" (this is the international prefix to dial outside of Mexico). Then dial "1" (this is the international code used to dial to the U.S.). Follow that with the area code and phone number.
