Last year when we went to Europe (Italy, France, Greece, Malta) I got a European sim card for $50 that allowed me to talk & text back to the states whenever we were in port or on land. When we landed in Barcelona I installed the European sim card in my phone & I was good to go. It included 10 GB data in 4G/LTE, 120 minutes talk time, 1,000 texts.
