Just purchased a skype phone number. Chose a local area code so family can call me while Iam in Italy. Will there be an additional charge on their cell phone when they call me. They have unlimited calls and text on there monthly cell plan. Will I have to pay skype if I answer call to my skype number on my cell phone? If I purchase a premium subscription will I be able to call home from Italy on my cell phone? And how much will that cost per minute- or will the monthly premium price give me unlimited calling and text from my cell?
