Hi All,

I am trying to set up Google Voice and it requires a US number to call to establish the billing connection I guess.

I had a prepaid AT&T SIM, but it didn't allow me to roam internationally, so is of no use now (and probably expired).

Can anyone recommend a cheap prepaid GSM option that I can buy that will allow the number to roam and can also be recharged via the web? If I could buy this on Ebay and have it sent to me, it would be a bonus as well. I won't be making a great use of the SIM as I mostly use local provider SIM which is better than roaming.
