We've tried nearly every method of making international calls on the road and have put together the best three ways to keep connected while on the road. You may pick only one of these, or a combination of the three. But each serves their purpose quite well and should be considered by all travelers when heading out the door to a foreign destination, whether it be for a few days or a few years.
1) Calling Cards

Where do calling cards struggle? In many destinations the pay phone or public phone are going away almost completely. The places that pay phones are still prevalent are the places that you would likely need a calling card in the first place - airports, train stations, or bus depots to call home and let loved ones know you arrived at your destination safely. All else fails? Hostel and hotels are often more than welcome to let you use the phone at the front desk if the payment is covered under a calling card. (Photo "Card Design" by ilco)
2) Voice Over Internet Protocol (VoIP) Services

Where do VoIP services fail? Well, you need a computer and an internet connection. Mobile apps exist for these programs that will work on smart phones and iPods; however, the internet connection is still required and may be difficult to find depending on where you are.

3) Cell Phones and Smart Phones

What are the downsides to cell phones? There is no question, the price of carrying a phone while traveling is quite expensive if going abroad. Between universal plans, roaming charges, and the need to swap out SIM cards, the phone companies have tricks at every corner to drive up the cost. One wrong move and you may be in for a phone bill significantly higher than you anticipated.
But there are many good things about carrying a smart phone while on the road that you may not consider too. Live blogging is a new one. With international plans and a phone capable of uploading photos, you'll be able to share your experiences with the world within seconds of taking a photo. Meet a friend on the road? There is no excuse for not staying connected if you both have phones. (Photo "Smart Phone Icon" by loraw2000)
Bonus - When All Else Fails, Don't Do It!
Of course, when the above options are impossible for your current situation, don't be too upset! Traveling without having to stay connected with home at every moment is true freedom that everyone should experience. Put the computer away, leave the phone off, and experience the world for all it has to offer without a care otherwise. But if you are wanting to check in now and again, calling home with a calling card or internet service may not be so bad as a small safety net to let everyone know you're okay!
