A recent post by Google Voice gives some information on what they are offering to help those people affected by the earthquake in Haiti.
Info Posted by the Google Voice team.
Google set up a disaster relief page, which includes information and resources for anyone interested in helping out, and the Google Voice team also wanted to respond in our own way.
Particularly in the wake of such a catastrophe, for people in the US who have family in Haiti, it is critical to stay in constant contact with your loved ones, provide moral comfort, and offer daily updates to friends and family in Haiti.
To help those families, we’re offering free calling to Haiti through Google Voice for the next two weeks. To place a call using Google Voice, use the Click2Call button on the website, the Google Voice mobile app, or dial your own Google Voice number and press 2 to place an outbound call.
