I just returned from Italy and used the regular Telecom phone cards to call home regularly. A 7.75 euro card usually was good for 3 calls home of relatively short duration. Just break off the corner, insert the card, dial 001, the area code and the number. I never had a problem, unless the phone was out of order. I can't imagine an easier way to do it.

Hope she has a wonderful trip
