Are you simply unable to travel without your smartphone and a broadband connection? Take heart: under the right circumstances, you don’t have to leave home without your phone. Cellphone roaming in Southeast Asia isn’t just possible, it’s very easy to do. Certain U.S. cellular phones and most European cellphones will work in Southeast Asia; if your phone meets a few conditions, you’ll be able to call home on your own handset to tell the folks how you’re handling your Vietnam itinerary, or check into Foursquare while viewing the Singapore Skyline from the Marina Bay Sands SkyPark.
If your own phone doesn’t play well with your destination’s GSM network, don’t worry – you’re not altogether out of options.
