I would recommend calling Richie @ Jivetel - 718-551-9000. He can help you with many different calling options. When I was in Israel for 2 weeks he hooked me up with an american number that ppl had to call directly to my cell, and with an 03 number that I called from my cell when I wanted to call America. Rates are always different so I don't want to post here what he offered me but it should be pretty cheap.
