It's the 8GB CDMA version that's locked to Verizon.
You won't be able to unlock it or to use it as a phone on any other network. No Micro SD slot.
But you can use it as a WiFi only Android device, like an iPod Touch. It has Android 4.4.2 (KitKat on it.) I have one and it's a handy GPS / messaging / wi-fi voice device. Nice screen - especially for the price.
It's pried at $70 today, but it'll be $50 from 6/1/14 to 6/7/14.)
