Send/receive SMS (text messages) and place/receive calls from an iPad I'm looking for a solution to receive/place calls and SMS over the cellular network. 
For now, my best solution would be Skype, but i can't receive SMS with it. Is there an equivalent ? 

Thanks. 

Edit: it might be important : I'm in France, not in the US.
Google Hangouts would do it. You'd have to get a Google account, and a Google Voice number, and then you can send/receive calls and texts with it.

If you had an iPhone i think you could also use the iPad to place/receive calls using the iPhone cell connection.  I don't think this is what you mean though
