Abroad where? Most places, you can buy anything you need if you forget it. We used to say "tickets, money, passport", but now you don't even have a ticket. You can get boarding passes 24 hours ahead or at the airport. Check about your phone- Verizon has an international plan that you pay $10 on any day that you use your phone for data or calls. Then email and texts are free, you pay a little if you make phone calls. See if your provider has an international plan and if you need to sign up for it. You need an adapter for the plugs to charge your phone and any other devices. Electronics are dual voltage, so you don't need a converter. If you use a hair dryer or anything like that, I strongly suggest that you not take yours, but either use what your relatives have or buy a replacement once you get there. The converters for electricity don't work well, and I've burned out curling irons in other countries!
