Lori is traveling to Europe soon with her family and they all have iPhones, but they have separate carriers and plans. What's the best solution for them as they travel? Leo says first thing is to find out what their international roaming plans are. They're better than they used to be, but it's still pretty expensive for what they would get. International data roaming can cost thousands if they're not careful. Leo recommends using Wi-Fi as much as possible, and they should pre-cache maps in Google Maps. They can get a local SIM in the country they're visiting.
