I got mine from the Verizon store. I downloaded a Dialer app from Google Play and tried to make a call, but still no go. The app brought up a Dialer, but when I punch in a telephone number, and press Send, it just beeps and does nothing. The Sim card was from my 4G LTE phone. I swapped it over.
I was, however, able to make calls using Google Voice & Groove IP. But man, I would just love to be able to make calls just like a phone.

If you see them and can't use them that means the SIM you're using probably doesn't support voice and MMS. They're either there out-of-the-box or they aren't. If they aren't there's not a lot you can do about it.
