How can I access unlock screen?

[d ammit]

I am planning to unlock my Moto G 1st gen. All the instructions for doing so with a purchased unlock code indicate that a sim from a different carrier needs to be installed in order to get the unlock screen. I do not have another sim. Is there any code that one can enter to get the unlock screen?

Nope.
