No reason to not have an extra hobby phone or text/voice app.

You can do it with a physical hobby phone or you can use your main phone and just use a secure phone app for voice and/or text (the latter is preferable). Or you could use Skype. Or Google Voice. There are so many options to get yourself another number, securely, that you can use for texting or talking.

Most of the time it will be married guys that will definitely want a hobby number OR a hobby phone (and providers obviously). You really don't need an actual physical phone though to have multiple secure identities.

Let me tell ya something folks. Anyone who thinks having a physical hobby phone vs the many different methods of acquiring a virtual # & secure identity (which is arguably much better & has many security advantages for married men & providers) is mistaken.

I may put together an essay on the technical advantages of virtual vs physical, but that's not the point of this post.
