I've had Vonage for a while, makes it easy for me to communicate with China.
Recently they launched Vonage Extensions. This service is free for Vonage customers and allows you to use WiFi to access your Vonage account and make/receive calls without using your cell phone data.
For those who have Vonage, download it! It's a great service! I was in China all week, and talked with my wife/daughter without paying for a call. I just hooked up to available wifi, launched Vonage on my cell and made the calls. Clear calls!!
I never really push products on here, but for those who travel internationally it's a great service.
