Computer, laptop, cell phone?
Make sure you check into cell phone coverage plans before you go and whether you can use the same phone or another when you are overseas. In most cases, roaming charges will cost you a fortune if you keep your US phone service. So you will want to look into getting a local plan in your target country.
Are you going to take a computer/laptop with you? Rely on using the school's equipment? Buy one while you are there? Keyboards are different, power supplies are different. The number of computers available may also be totally different.
Often the programs in your host country will have lots of detailed information for you in a Student Handbook.
