We sure travel a lot and we love apps that can make our live easier.
Here are 3 that can help you while you are away:
mysims2go: This app finds the best carrier to transport outgoing calls and help you minimize roaming fees or international charges.
MeetingWave. This one, unfortunately is just for IPhone users. Besides this sad fact, it is a good app for you to find local networking events, happy hours etc.
Fring.com: Allows you to make and receive video calls for free to or from any smartphone. It also has text chat.
