No VoIP Calls on Google Voice for iPad and iPod Touch
Google Voice now supports iOS devices without cell service. Released today, the updated version of the app supports the iPad and iPod touch, but only to a point. While it allows iPad and iPod touch owners to send and receive text messages or check voicemail from their Google Voice accounts, it won’t allow them to make VoIP calls. That said, it can be used to initiate calls on true phones associated with a Google Voice account, if you ever feel compelled to add another step to the phone call process.
