You can also choose to use a Raspberry Pi Zero which will save you some $15 from the total price, but for the sake of simplicity of this tutorial, we'll be using the Raspberry Pi 3 Model B. I've only tested these two Raspberry Pi's, but I see no reason why Virtual Modem wouldn't work with any Raspberry Pi. If you have success with the other Raspberry Pi's, feel free to let me know :)
On to the next part!
