This forum is amazing! I was looking for a roaming account that wouldn't cost me a fortune or need lots of upfront cash (cos I won't use it that much). Ipass wanted 100 Euros upfront, and charges $2.99 an hour in the USA.
MaGlobe was happy with $15 upfront (I chose $30) and charges $0.59 an hour in the US.
So now I have a MaGlobe ID to add to the lengthening list!
Thanks, RTFM - just what I needed!
