Using a cellphone overseas??

Posted by avatarShannon last updated May 1, 2006 at 11:50 pm

I am wondering if someone can explain a little bit about using a cell phone overseas. I am going to South America to visit some friends and one has asked if I can bring a camera phone for him. If i bought a phone, would it work overseas? All i really know about this is it needs a SIM card, but that means almost nothing to me. Will any brand work? or none? Please help!!
