fyi i have been using worldxchange for a couple years, they are almost as good as onesuite, anyway better than almost any other NON-prepaid provider I have found. they provide both dial 1 and 10-10/1--15 access -- I use the 10-15. The two rates that I use by far are interstate in US & to region 6 in mexico. the rates for these regions on two different codes:
10-10-629 : when you know call is short (fax, whatnot) -- 7.9/min US, .17 to mexico
10-15-992: 10 minute minimum - .04 US, .14 mexico band 6 (i almost alwasy use this)
these rates are 24/7 and there are no extra fees (except fed taxes); they bill right to your phone bill. I think if you get dial 1 service they give you another 5% discount. these rates have been the same for a few years now -- they wre a lot more "hot dealish" three years ago, but they are still not bad if you don't like the hassle of prepaying. I see they have other plans that are cheaper (eg onecents - .049 US/ .13 mexico)

by the way, has anyone ever found
a way to call cheaper to mexico than for .13 (outside of mexico city and us border area?) it would be a great help to get a better rate, we call there at least an hour a week!
edit: changed prepaid to "NON prepaid" & fixed other typos, oops
