Can you text an iPod from a Samsung smartphone?
They do not both need the texting app, only the iPod needs it. And yes it has to be connected to wifi. Pinger is the one I use
You cannot do this unless both devices have texting apps running on them like Whatsapp. In addition to this, the iPod will ahve to be connected to a Wi-Fi network. This is because iPods do not support , 2G,3G or 4G networks which texting relies on.
