I am in the same boat.. sort of. My 4S is unlocked... accident care of AT&T

. Last October I went to the UK and bought a local Sim card. It was fine for what I wanted it for but it is a pain in the butt because you have to tell everyone your new number. They also gave me a temporary US number to use. Fast forward.... I am going to Italy for 2 weeks with hubby... he works, I get to play. Now I am in a quandary because I really only want a phone to connect up with him and he has a US phone number. Getting a local Sim and calling a US number may not be worth the effort and it may turn out to be more costly. I have seriously been considering just getting an International Plan from AT&T to use for the once a day calls or text messages. Unless it is an emergency, no one else is going to call me and I can use Skype to contact them when wifi is available.
Any thoughts?
