Sarah is traveling to Vietnam and Cambodia later in the year and doens't know what to bring with her for her technology. Leo says that most electronics are now rated for 110w-240w, so they can handle any circuit all over the world. But that plugs will be different. There are travel adapters for sale that you can pick up to plug in your power plugs. They should be the same as China, but you may want to be sure it's not a french adapter since Vietnam was once a French colony. As for your data and international roaming, it depends on your carrier.

Suzanne is going camping in Russia for a week, out in the middle of nowhere. She wants to know how she can charge her phone while out there. Leo says that Suzanne may not be able to use the phone in the mountains. But in the city, she may have a better option. Verizon now has an unlimited data day pass for about $10/day. So when she's in the city, she can turn it on. For charging them, Leo recommends GOAL ZERO since their solar chargers are really well made.

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.

Carl's wife is going to the Philippines soon and he wants to know the best way to stay in touch internationally. Leo says that the real answer is WiFi.

Marty worries that bringing his phone overseas will cause him to rack up thousands in cell phone bills. Should he just keep his phone on airplane mode? Leo says no, that turns off everything.

That way he can still use maps for travel.
Paul and his wife are traveling to Croatia Saturday and he's worried about data roaming charges. Leo says that international data is rapidly changing thanks to T-Mobile's free Edge data plan that started last year. As such, AT&T has changed from offering an expensive data package to a "day pass."
Google Fi is a solid option, because they would pay as they go at $10 a month. If they have a Google phone, then they'll be in good shape.
Joe is traveling to Asia and he wants to know if it's better to get an international data roaming plan or get a local SIM wherever he goes. He uses Verizon. Leo says that Verizon is the most international unfriendly mobile carrier. Sprint, AT&T, and T-Mobile have their own reasonable plans (especially T-Mobile that offers a free slow internet). Verizon has a $10 a day plan, though, which isn't bad, but it adds up. It's going to be the easiest way since he would have to have a different SIM for every country he visits, and his phone number will change with each new SIM card.
