I hate not being included in "everyone".
(Google Voice is not available in your country.)
(Google Voice is not available in your country.)
That having been said, you don't get as much use out of it as if you lived in the US. But I use it for free unlimited SMS (incoming and outgoing) to my friends in the US, and for voicemail with an American number .
If you want a Google-voice like service that works in Europe, then try 3jam (although it's not free).
when I'll get the US number, what should I do next?
