Cell phones can be very handy when you travel. They can act as a flashlight. You can take a photo of your hotel and if you can’t communicate with your cabby, show him a picture. You can take a photo of important things, like your passport, itinerary , immunization record, medical history, medication list, phone numbers of your credit card companies international line to report stolen or lost cards, and the number of your travel health insurance company.
Hey, you can even make phone calls!
