Does anyone (from the US preferably) have experience using the Skype app as a primary phone connection while abroad? I don't need to be able to communicate at all times but I need to be able to call the US while I'm in Italy and thought Skype might be a good solution to use while on WiFi. I would also like a number that people can call that would ring my phone (the Skype app) while I'm connected to WiFi as well. I don't need to be able to call or received calls on 3G (don't want to pay for international roaming) but would like to be able to receive voicemails. Can Skype handle this and what are the best services to sign up for? Thanks.
