Google Voice Invites are difficult to get. But US Military Personnel can get priority Google Voice invites thanks to a new initiative by Google to help them communicate with family and friends.

The most important requirement is that you need a .mil email address, which is proof of being in the US military. Secondly it is necessary to be in the US and have a US phone to sign up for Google Voice. Request an invite at the special military page and Google promises to send you a Google voice invite in 1-2 days. For rest of us, there is the usual Google invite request page.

Google Voice gives you a unique single phone number for all your phones, voicemail becomes as easy as email, and many calling features are free. This video will give you a better idea of how useful your Google number is.

So far, I am not impressed with Google Voice. I understand this is a new service and that this is bascically still in beta but it’s just not what I have come to expect from Google. Don’t get me wrong. I love Google! They make some nice stuff and I use most of them. It’s just that some of the basic features are still in alpha as far as I am concerned. Just check out my Flickr photostream to see what I am talking about.

I’ll post again once I have had more time to play with the service.
