Can someone point me to 3G coverage maps for Italy. I will be in SouthEast Calabria for an extended period and would like to use a data card for my computer. I cannot find coverage maps specific to 3G in that area.

The only official 3G map in Italy is the one in the site of 3, but it's really small:

If you tell us where exactly you are going we can tell you something more. But unless it's a mayor town, I think you won't find much 3G, expecially in Calabria.

I will be in Gioiosa Ionica most of the time. I know a few of the surronding towns have 3g coverage, but I cannot find a map showing the extent of the coverage.

Thank you for your assistance.

According to the info supplied by operator websites, neither TIM nor Vodafone IT have 3G coverage in Gioiosa Ionica (RC). Only GSM/GPRS coverage.
You can benefit of EDGE data transfer speed if you use TIM, not really 3G speed but better than nothing.
