Will I be able to get service in Italy with the galaxy tablet?
If it is wifi capable, it will work in wifi areas. You may find free areas, or you may have to pay for it.
...and even the free WiFi will be a secure hotspot requiring a password, I do not recall seeing a single open WiFi signal. If you are talking wireless telephone service, the expense may be greater than the worth.
Patty, here is a link to a message thread that itself contains links to other discussions about using an iPad in Italy. It should contain some information that will also be applicable to a Galaxy Tab. IPAD 2 with wireless and 3G for Italy Hope this helps.
