A 3g pre pay dongle that works on a MAC?

[sunkissed]

Further to my earlier post (viewtopic.php?f=35&t=21516)
I returned my Movistar 3g dongle to the shop and they couldn't get it to work either and called Telefonica who said it there's no official support for the Mac. I got a refund but lost the 20 euros credit I added when I bought it

Can anyone advise of any other pre pay 3g dongle/modem (Orange, Vodafone etc) that works on a Mac without a load of hassle as I'm travelling away again.

For Portugal, I have a Kanguru pre pay modem (I think it's owned by Orange) and it works fine.

thanks
