Just because your old smartphone isn't connected to a carrier, doesn't mean its dumb!  Did you know that you can still make calls from your old smartphone even when it isn't shacked to a mobile phone carrier?  Its true.  

Make A Wifi Phone

So you bought a new phone and now you have this really expensive paperweight sitting in your glovebox.  Your old smartphone may not have data service, but that doesn’t mean you can’t make calls. By using Skype, it’s possible to make calls via a WiFi connection, which will continue to work. Google Voice is also an option.

Whatever you choose to use, your old phone can be used just like a normal one as long as it’s on your WiFi network and the VoIP app you are using is active. The WiFi phone can be used as a backup and/or used as a landline replacement.
