Should You Buy a SIM Card?
After trying it both ways, I will definitely be buying a SIM card when I travel abroad again. For less than $20, the ability to use my smartphone just as I do at home was completely worth it. I also found that being conscious of data usage meant that I was still "unplugged"—not checking emails and apps as much as I do on my phone at home—but when I was lost and needed to use the GPS feature on Google Maps, having the prepaid data was invaluable.
Also, being able to text and call to meet up with local friends was very handy. Even if you don't know anyone in the country you're visiting, having the ability to call a restaurant to make reservations, your credit card company if it freezes your card, or a tour that you want to book is great.
